Après plusieurs voyages en Afrique (Sénégal et Burkina faso) et en Asie (Inde et Indonésie), je souhaiterais découvrir un autre continent, celui d'Amérique du Sud.
La question est quel pays me conseillez-vous?
Période: Mai 2009
En sachant que j'ai 27 ans et que je pars 3sem, en sac à dos. Je privilégie la nature et les paysages aux villes et capitales. Je cherche un pays accueillant, avec un minimum de sécurité, qui possède plusieurs facettes (plage, jungle, tribus, etc.). Je me déplace en transports locaux, voire en voiture avec chauffeur si nécessaire.
pour ma part, je te conseillerais de voir la bolivie, qui t'offre au nord la foret amazonienne, au sud ouest la cordillère des andes, et surtout l'incroyable salar de uyuni;
en ce sens, tu pourais faire un circuit bolivie-chili-argentine en traversant le salar et ses lagunes (paysage le plus splendide qu'il m'ait été donné de voir), en t'arrétant à san pedro de atacama au chili (super touristique mais on peut y faire des expéditions qui valent vraiment la peine) puis en remontant par le nord de l'argentine en t'arrétant du coté de salta, jujuy, et dans les villages d'une vallée sublime qui rejoint la bolivie, par exemple humahuca, tilcara.. (pour cette boucle, depuis Sucre disons, 7 jour grand minimum puisque 3 pour le salar)
Et le reste de la bolivie vaut vraiment le détour. Les habitants sont très accueillants, les voyageurs en général sont des routars donc les bons plans circulent bien, on peut trouver de toute qualité en hébergement, de l'hotel de passe glauque presque gratuit à la posada charmante et tout confort, pas bien chère non plus au final. les touristes sont tres bien traités puisqu'ils aident au développement local... Pour la sécurité, je pense que c'est comme partout, à conditions d'être vigilent, il n'y a aucun probleme -attention aux bus, ils tombent "souvent" dans les ravins... mieux vaut choisir les meilleures compagnies-
en termes de budget c'est très abordable, on trouve des plans pour "poches percées" partout: tu mange au marché, tu dors dans les petites auberges, suffit de pas avoir écrit "pigeon" sur le front ;-)
pour plus d'infos n'hésite pas à demander (je connais d'autres pays aussi, l'argentine, l'uruguay, le venezuela...).La boucle bolivie-chili-vénézuéla est pour moi la meilleure option pour 3 semaines.
En trois semaines l'Equateur est l'idéal, le pays assez petit par rapport à ses voisins, tu pourras donc te déplacer facilement ( le réseau de bus est bien fait) de la cordillière à l'Amazonie et à a côte avec toutes les différences de paysages que cela comporte.
Pour ce qui est de ce que tu appelles "tribus", tu trouveras tout un réseau de projets de tourisme de proximité mis sur pieds par les communautés indigènes.
N'hésites pas si tu as des questions sur l'Equateur, je rentre tout juste (fin novembre) d'un cinquième voyage là bas.
Merci pour vos réponses. En effet, mon coeur balance entre l'Équateur et la Bolivie...
Mais j'ai lu qu'au mois de mai, il y a en moyenne 16 jours de pluie/mois. Qu'en penses-tu, toi qui y a été si souvent? Est-ce juste? Au vu du climat, quels sont les meilleurs mois pour y aller? Car j'avoue que je ne quitte pas la pluie de la Belgique pour en retrouver une autre.... As-tu été en Bolivie, si oui quels sont les avantages/inconvénients de l'un et de l'autre?
J'aimerais également avoir des infos sur les itinéraires de 3semaines effectués en transports locaux pour l'Equateur et pour la Bolivie. Qui peut m'aider?
Un grand merci, vous êtes toujours d'une grande aide pour le choix et les préparatifs de voyage....
En principe, en Equateur, il commence à faire beau, à partir de la mi-avril. Et d'après mon expérience, en cette période, quand il parlent de jours de pluie, c'est souvent une averse de deux ou trois heures.
Cela fait dix ans que je visite l'Amérique du Sud et je vis depuis deux ans en Equateur et la plupart de mes voyages ont eu lieu en mai-juin avec globalement du bon temps. Toutefois, ces deux dernières années, le climat est un peu fou dans ces régions.
Pense aussi qu'en Amazonie, quel que soit le pays, c'est tout à fait normal d'avoir une bonne averse (En anglais, Rain forest)
L'Equateur te permet d'avopir quasi tous les types de paysages et de populations en parcourant des distances "courtes" par rapport au continent sud-américain. En Bolivie, il y a des très beaux coins aussi mais les distances sont plus longues et les routes plus difficiles.
bonjour.difficile de te conseiller!moi j'ai eu un coup de coeur particulier pour la bolevie, des gens adorables des paysages tres beaux, une vie tres douce.
le seul inconvenient c'est la route car elle est un peu dangereuse.moi j'en ai fait abstraction, et j'ai pas mal bougé sur place.je suis allée en equateur mais je le trouve un peu plus moderne.
apres c'est à toi de faire ton choix.bon courage

Hi everyone,
We're planning a trip to southern Chile in November. Here's our tentative itinerary:
Day 1: Arrival in Santiago, then a flight the next day to Balmaceda where we'll pick up a rental car to reach Coyhaique.
Day 3: Walk in the Coyhaique National Reserve, then continue to Puerto Chacabuco. Return to Coyhaique for the second night.
Day 4: Drive to Villa Cerro Castillo for a hike in the national park. Continue to Puerto Tranquilo and stay there for 3 nights.
Day 5: Boat tour on Laguna San Rafael.
Day 6: Day trip to Monte San Valentin Glacier.
Day 7: Excursion to the Marble Chapels, then drive to Puerto Guadal. We'll stay there for 3 nights.
Day 8: Walk along Lago Carrera and return to Puerto Guadal.
Day 9: Rio Baker Valley and, if possible, a glacier excursion.
Day 10: Drive to Cochrane and hike in Tamango National Reserve. We'll stay 2 nights in Cochrane.
Day 11: Walk in the Chacabuco Valley.
Day 12: Drive to Caleta Tortel. We'll stay there for 2 nights.
Day 13: Cruise in the Rio Baker delta.
Day 14: Return to Cochrane.
Day 15: Return to Balmaceda in two stages.
Day 16: Continue the return journey.
Day 17: Return the rental car and head back to Santiago.
After this, we're also planning to explore northern Santiago. I'll post about that part once I have a clearer idea of the route.
What do you think of this itinerary? Is it doable in 17 days?
Thanks in advance for your tips and recommendations.

Hi everyone! So happy to be back on this forum—it’s packed with such useful info! 🙂 My husband and I are planning a 2.5-week self-drive trip to Colombia at the end of the year, including some domestic flights. My first question is: is it possible, easy, and safe to do a road trip in Colombia?
Below is our draft itinerary (with questions at each stop):
29/11: France → Colombia. Overnight in Bogotá.
30/11: Exploring Bogotá: La Candelaria and Montserrate.
01/12: Gold Museum (closed on Mondays). Drive to Zipaquirá (1.5 hrs) to visit the Salt Cathedral. Then drive to Villa de Leyva (3 hrs). Explore the town. Overnight in Villa de Leyva.
02/12: Return to Bogotá via Laguna de Guatavita (5 hrs). Is it worth the detour? Overnight in Bogotá.
03/12: Flight to Pereira. Drive to Salento. Overnight in Salento.
04/12: Cocora Valley (hike among the wax palms) followed by a drive around the area. Are there any waterfalls or other sights nearby?
05/12: Visit a coffee finca—any recommendations? Then explore the surroundings: Filandia, Manizales, waterfalls? Hot springs? Which ones?
06/12: Flight to Medellín.
07/12: Exploring Medellín: Centro, Plaza Botero, Comuna 13. How do you visit Comuna 13? Is it easy to get around Medellín? Metro? Buses?
08/12: Drive to Guatapé (2 hrs). Visit the town, stroll around the lake, then El Peñol. Overnight in Guatapé.
09/12: Return to Medellín.
10/12: Flight to Santa Marta. Drive to a hotel near Tayrona Park.
11/12: Tayrona—El Zaino entrance.
12/12: Tayrona—Palangana entrance, then Bahia Concha and Santa Marta. What do you think?
13/12: Drive to Minca (45 mins). Can we reach the village by car? Pozo Azul and Marinka waterfalls. Overnight in Minca (or back in Tayrona?).
14/12: Drive to Puerto Nao (5 hrs). Stop in Ciénaga on the way + boat tour in Nueva Venecia and/or Buena Vista? Not enough time? Overnight in Puerto Nao.
15/12: Exploring Cartagena: Centro, Getsemaní, the walls + La Boquilla if we have time.
16/12: La Boquilla (is it really worth it?) if we didn’t have time yesterday, then back to the beach.
17/12: Return to France.
So, what do you think? Is this doable, or should we tweak it? Thanks in advance for your invaluable feedback and tips! 🙂
Hi there, I’ll be in Brazil from December 10th to the end of February.
I’ve sketched out a rough itinerary but I’m not sure how to arrange it—considering the climate, year-end holidays, and Carnival.
Basically, I’m thinking of the Amazon, the Northeast coast with Lençóis Maranhenses National Park (but skipping Chapada Diamantina),
Ouro Preto, Paraty, and Ilha Grande—but no Rio visit.
Is this doable in 3 months?
Which direction should I take for this itinerary?
Thanks in advance!
Hi everyone, does anyone know the agency Ventura Travel Agency (not ventura travel)? After lots of research and quotes, it’s the only one offering Uyuni at a reasonable price while meeting all the criteria: transfer to the border, private-room accommodation, and a very fair rate. Other agencies or guides either offer shared rooms, no border transfer, or prices that are way too high. But I’d love to hear some reviews about this agency. Thanks in advance!
Hi everyone,
We're planning a trip to Chile to visit the Atacama Desert and then head toward Putre, Lauca, Salar de Surire, etc.
Which would be the better time to go, April or November?
Is an SUV enough?
Looking forward to your tips!
Hi everyone, French travelers in Chile—what credit cards do you use for your various car rentals in the country? I’m traveling in September and was planning to switch my regular debit card (a VISA PREMIER in deferred debit mode) for the deposit guarantee.
My rentals are with Figal in Punta Arenas, Econautos in Arica, and Chilean Rent a Car in Temuco, and all of them want the deposit on a credit card. For me, deferred debit *should* work, but I’ve read comments saying the opposite.
How’s it actually working on the ground with these rental companies right now? Will a deferred debit card work, or not at all?
In France, banks don’t issue credit cards, right—or am I mistaken?
Hi everyone, is it still possible to travel in Ecuador outside the Amazon region? If so, do you have a reliable agency to recommend? All your recent experiences from the past few months would be greatly appreciated. Thanks so much
Hi,
We’re heading to Buenos Aires for 3 days in November and would like to do a guided tour of a few neighborhoods. There are "free" tours, but none in French. Does anyone have a guide to recommend so we can really get to know the city beyond just the architecture?
Thanks
Hi there,
I’m desperately looking for info on the schedules and routes of (shared) boats to visit the islands of Lake Titicaca.
From what I’ve found, there’s a *combi* (bus) that leaves from Puno to go to Llachon. Where do you catch it? What are the schedules and frequency? Does it take about 1 hour?
Then in Llachon, you can take a boat to Amantani (45 min). Same question—where do you check for frequency and schedule?
After that, from Amantani, boats go to Taquile and then Uros. Do you have enough time to visit the islands between two boats? Frequency and schedule?
The goal is to do this tour independently (no agency) over 2 days. Thanks for any tips you might have!
I just got back from a trip to Bolivia and wow—what a wake-up call. It’s not the easiest country, but it’s absolutely stunning.
I started with Isla del Sol, perfect for easing into the altitude at a relaxed pace. Try to stay in the northern part of the island—it’s quieter and the views are insane. And the trout there? Unreal. Quick tip: bring cash in small bills; they almost never have change, and cards are rarely accepted.
Next up, La Paz. The city’s pretty wild, built in every direction. I did a few hikes in the area, including the famous Charquini Lagoon (the blue lake) at over 5,000 m—let’s just say I struggled 😅 but it was so beautiful it was totally worth it.
After that, I headed to Sajama. It’s cool, especially for the hot springs, and I stayed in Tomarapi. But honestly, if you’re short on time, you can skip it without too many regrets.
The highlight of the trip: the Salar. I did it starting from Tupiza, and I *highly* recommend going Tupiza → Uyuni. Way less crowded at the start and the landscapes are super varied. For the tour, I used SplitYourGuide to find a group, and it worked out great. Super handy for splitting costs and meeting people.
I wrapped up in Sucre—this city is gorgeous, all white, with such a chill vibe. And the salteñas + ice cream? Next level 😋
Bottom line: Bolivia’s a bit rough around the edges, sometimes exhausting (shoutout to the altitude), but it’s 1000% worth it.
If you’ve got questions or need tips, I’m happy to help!

I was planning to go to Réunion and stay in half-board accommodation with non-professionals, but it seems that’s not really the custom there—or maybe my budget isn’t big enough.
So, since I’ve already traveled around Ecuador and Peru, I’m now looking at Argentina, especially for its mountains (like the ones in Réunion that tempted me, even though—frustratingly—I could only admire them from below).
I plan to get around by bus and don’t know in advance where I’ll sleep, so I won’t book ahead. If I like a place, I might stay for several days.
I know that in Chile, it’s easy to find half-board accommodation, but what about in Argentina?
I’d like to stay with locals in half-board without it being a professional setup. I’m not sure if this is common practice there. It’s up to me to find someone willing to host me.
What do you think?
What would be a fair price (keeping in mind that 40 to 50 € is the max I can spend on accommodation, breakfast, and dinner)?
Hi everyone,
We’re heading to Patagonia for three weeks in November, starting from Coyhaique in Chile.
We won’t have a car, and I’m struggling to find information about transportation options for a few parts of the itinerary we’d like to do:
1) From Perito Moreno (the town, near Los Antiguos), we’d like to travel down Ruta 40 to visit Perito Moreno National Park and then cross into Chile via the Paso Roballos (at the latitude of Bajo Caracoles) to reach the road to Cochrane. Without a car, it seems we’ll need to use private agencies to get to the national park—do you have any recommendations or suggestions? Also, does anyone know if it’s possible to cross into Chile via Paso Roballos (from Bajo Caracoles) without a rental car? That is, without having to go all the way down to El Chaltén or back up toward Perito Moreno/Los Antiguos, etc.?
2) The second stretch that seems a bit tricky (though still easier, in theory) is from Caleta Tortel to Villa O’Higgins on the Chilean side. Do we have to go back through Cochrane, or are there ways to get directly from Tortel to Villa O’Higgins?
3) Finally, we’d like to hike into Argentina (El Chaltén) from O’Higgins. Any recommendations for this? Do we need to go through an agency? What’s the estimated duration of the trek?
As you’ve probably gathered, we want to visit some off-the-beaten-path spots but don’t have a car, so we’re looking for the best possible compromises.
Thanks so much in advance for all your suggestions!

Hi,
we’re planning a round trip from San Pedro de Atacama, Chile, to Salta, Argentina, in two months. On the way there, we’ll take the northern route via Susques, Route 27, then 52. But for the return, we were thinking of taking the southern route via San Antonio de los Cobres, Route 51, then 23. Is it similar to the northern route in terms of road surface? How busy is it, and are there gas stations? Basically, should we be worried about doing it in an SUV that’s supposedly 4x4 but has regular road tires and no second spare wheel, obviously...
I’ve seen that we can stop over in San Antonio de los Cobres.
Thanks for your feedback.

Hi,
we’ll be in Calama at the end of March 2026, and I’m looking for a reliable car rental there for a 7-day road trip to Salta, Argentina. But I’m struggling with the car rental agencies in Calama because the reviews can be scary. I saw Gyg, which has great ratings, but I’m a bit wary (5/5 from 59 reviews—either the guy’s amazing or it’s fake...), but I can’t find any recent reviews on VF in general.
For Punta Arenas, I booked with Dachelet and didn’t have any issues with email exchanges.
Thanks in advance.
Raf.
I’m planning the trip of my dreams for next November—Chile!
I’d love to get your thoughts on my potential itinerary. I know it’s a big investment in terms of both time and money, so every bit of feedback, suggestion, or info helps immensely. Thank you in advance!!
1-Flight to Santiago
2-Explore Santiago
3-Explore Santiago
4-Bus from STG to Valpo (2h) + visit Valparaíso + night in Viña

7-(Very early) Valle del Arcoíris + Laguna Cejar + Valle de la Luna
Good evening,
We’d love to go in November to enjoy some beautiful beaches for about two weeks, preferably around Bahia, as November/December seems like a great time.
We’ve already traveled to Brazil several times and know the south of Rio as well as the region between São Luís and Fortaleza, and Chapada Diamantina...
What advice would you give us: the south with Itaparica, Morro de São Paulo, Boipeba, Barra Grande—or all four? Or maybe the north?
Thanks in advance for your help

Hi,
During an upcoming trip to Peru, we’ll have one day to explore around Arequipa (excluding Colca Canyon) with a car and driver.
We’ve got a few options:
- Toro Muerto petroglyphs and dinosaur footprints at Querulpa
- Ruta del Sillar and Quebrada de Culebrillas
We’re a group of 6 friends with an average age of 70, all mobile, and we’re planning a trip to Peru in September/October 2026. Below is an idea of what we’re looking for: a French-speaking guide, accommodation in 3-star hotels or homestays with comfort.
Duration: 16 to 20 days on-site.
Visit the main sites with immersion in the culture and way of life.
Which francophone agency in Peru would you recommend? Thanks
Hi there!
I’m putting together my itinerary for Brazil, looking for beautiful natural spots with wildlife, flora, and great hikes...
I’ve come across the Cananeia / Super Agui / Ilha do Mel region and the PETAR / Intervales / Alto Ribeira area.
Has anyone here been to these places? If so, do you have any recommendations for accommodations and activities?
Thanks in advance!
Best,
Olivier 🌍
I’ll be in ARICA in northern Chile at the end of May 2026 and want to get to TACNA.
Are there taxis, buses, or collectivos that run the border crossing route?
After that, bus to AREQUIPA (Peru): any bus company you’d recommend?
Hi there,
We’re spending 3 weeks in Brazil, arriving in São Paulo—a couple plus a teen—and we’ll have a rental car.
We especially love nature: hiking, wildlife watching, birds, etc.
We’re planning to wrap up with a week around Paraty and Ilha Grande.
We’re not really into visiting big cities like São Paulo or Rio unless you think we’d be missing out big time.
So we’ve got 2 weeks to explore the south/southwest region of São Paulo.
What do you recommend?
National parks? Off-the-beaten-path nature spots? Iguazu Falls?
Hi there,
Do you have any recommendations for comfortable accommodation in Leyva and Barichara? We're also looking for a guide to explore the areas around these two towns (parks, waterfalls, etc.).
Thanks for your tips!
I visited Colombia in January 2016 and I’m heading back from August 6th to 17th with the same airline to see how things have changed. Starting August 18th, I’ll continue with independent exploration. I prefer slow travel and enjoying places at my own pace.
Any tips—especially for getting around or must-see spots—are welcome!

Hi there,
Three years ago during a trip to Java (no, I didn’t post in the wrong forum!), I came across the address of former miners who had switched to “tourism” and organized nighttime ascents of the Kawah Ijen volcano and descents into the crater.
So I was thinking—maybe there are miners on the salt flats too, either former or still active, who do the same thing. If you’ve had an experience like this, I’d love any tips you can share.
Thanks in advance.
Hi there, since there isn’t much recent info on how to get to MP, I’d love to know if there have been any improvements to the "route" to Hydroelectrica. Is it feasible to drive there in February? And is it still possible to walk all the way to Aguas Calientes? I think I read somewhere that it’s no longer allowed??
Do you think I can buy Machu Picchu entrance tickets last-minute at that time of year, given the weather?
A group of friends and I are heading to Brazil in March 2019 and we’d love to attend the Carnival parade. I could really use your help because I’m struggling to find reviews for online ticket sellers for Carnival.
I came across rio-carnival—is this a reliable agency?
Do you have other agencies to recommend or experiences to share?
Any advice is welcome.
Everything You Need to Know About Argentina’s Currency Exchange Maze (2026 Edition)
Hi fellow travelers,
Packing your bags for Buenos Aires? Watch out—here, money is a science almost as complex as the dance steps in a tango!
As of March 2026, the situation has shifted dramatically: the "Blue" (parallel) rate is now neck-and-neck with the official rate. To save you from losing your hard-earned euros in bureaucratic mazes or "disastrous" exchange rates, I’ve laced up my reporter boots and hit the famous Calle Florida for you.
In my latest video (and the accompanying article), I take you behind the scenes of currency exchange:
Arbolitos and Cuevas: Who are they, and can you still trust them?
The Rate Showdown: Why Banco Nación is currently the worst place for your savings.
Western Union: Why it’s often your best ally right now.
Cash or Card? The little secret to getting an instant 10–15% discount at restaurants or hotels.
The Bill Trap: Why your 500 € notes or stained dollars might stay in your wallet.
Argentina changes fast—*very* fast (by the end of March, today’s advice might already be old news!). So don’t leave without checking the market’s pulse.
