Here’s the thing: ever since Sumatra, I’ve become picky.
I don’t want the grey-green of the North Sea anymore. I want turquoise, crystal-clear waters—so clear you can see the coral 10 meters down. You see it, right?
I don’t want those "equatorial greenhouses" you visit politely in well-maintained park alleys. I want wild, humid, buzzing jungle—hostile yet captivating at the same time.
I don’t want wheat that becomes flour that becomes bread that dips into soup. I want jade-green rice terraces rippling in the wind through distant valleys, where you can enjoy a nasi goreng.
I want more! I want coconut trees in sight, fine sand underfoot, smiles in the streets, and the world’s largest volcanic lake with a charming little island inside. Simple, really!
Here’s the 26-day itinerary across this island:
LAKE TOBA: 4 days
It’s the story of a volcanic island at the bottom of a lake at the bottom of a volcano.
The lake is Toba. The island is Samosir.
Time here is for pausing. Time is for savoring lobsters, swimming in calm waters, enjoying the mild climate without the tourist crowds. And when time isn’t for pausing, it’s for wandering at a leisurely pace—walking, canoeing, or scootering. You’ll discover lush jungle landscapes, Batak villages (a Christian ethnic group) with surprising architecture, small inner lakes, and breathtaking views from the summit.
Tuk Tuk, the main village on Samosir, offers plenty of charming restaurants and accommodations. But you can also venture into lost villages and find a peaceful haven with locals... and never want to leave. If you want to know more and see all the photos, it’s here: Lake Toba.

BERASTAGI: 2 days
We’re in the heart of Sumatra’s volcanoes. Berastagi is the starting point for climbing the smoking, sulfurous mountains nearby. The town itself isn’t interesting, but you’ll find everything you need (markets, lodging, warungs, restaurants...).
For the volcanoes, the most accessible is Gunung Sibayak. No guide needed—the hike only takes a few hours (depending on where you start). All accommodations provide clear directions. The summit is only 2,095 meters high.
Oh, this volcano isn’t all that impressive. But it’s really nice to feel the earth’s warmth in this lunar, ochre-yellow landscape, through the hissing fumaroles escaping the rocks.
The place is stunning on a clear day, or even better if you’re lucky enough to rise above the clouds.
Across from it, you’ll see the splendid view of a more turbulent neighboring volcano: Mount Sinabung and its dramas.

The jungle KETAMBE: 4 days
This is the real jungle. Not the Hollywood studio kind or the city zoo version. No: the jungle. Teeming, dense, humid, and noisy.
With the help of a specialized guide, we spotted plenty of insects and birds, long-tailed macaques, "Thomas leaf monkeys," and the much-anticipated orangutan...
Ketambe is less touristy than Bukit Lawang. The animals are completely wild, not "semi-tame." This part of Gunung Leuser National Park is also harder to access, but the experience remains authentic even as tourism grows.
In these times of deforestation advancing like a terrestrial cancer, experiencing the jungle is a unique, moving, essential moment: it’s "For the wild beauty of the last primary forests" (Le Monde, November 13, 2013).
Leech socks and a small backpack: you’re ready for a multi-day trek? Off you go for muddy slopes, liters of sweat, hot rivers, endless green... and primates!
Sleeping at least one night is a memorable adventure: the sounds of the jungle in total darkness deliver their dose of sensations, chills, and lifelong memories. If you want to know more and see all the photos, it’s here: the Ketambe jungle.

PULAU WEH: 5 days
It’s all here: turquoise waters, fishing villages, thrilling scuba diving, lush jungle, coconut trees, warungs, and fresh fish on abandoned beaches with seashells and crustaceans.
A small island north of Sumatra (50 minutes by ferry), Pulau Weh is slowly recovering from the 2004 tsunami. For now, the place isn’t overrun by tourists. But the infrastructure is more pleasant than in the rest of Sumatra. You’ll find some charming bungalows right on the water. Rent a scooter, and you can easily find yourself alone on a paradise-like cove for a romantic sunset.
For the party scene, uh... it’s pretty quiet! People come here mainly for scuba diving with its colorful corals (though some have bleached) and lively marine life. Snorkeling also reveals beautiful sights. If you’re not here to swim, there’s always lazing on the beach in a hammock, sipping while gazing at the turquoise waves. That’s great too! If you want to know more and see all the photos, it’s here: Pulau Weh.

LAKE MANINJAU: 2 days
The mist yawns slowly over the waters at dawn. When it finally lifts, you discover a blue treasure at the bottom of the old volcano’s caldera. In central-west Sumatra, Lake Maninjau is home to the Minang Kabau people. Less touristy than Lake Toba, it still offers equally beautiful landscapes.
By scooter, a full day is enough to circle the lake (40 km) through villages, jungle, and rice terraces: it’s very pleasant, especially the southern part where traffic is light.
You’ll find bungalows by the water, mainly near the village of Maninjau (yes, same name as the lake). From the crater’s heights, you can admire the whole of Maninjau (the lake!). To get there, you can navigate the 44 hairpin turns (!) by motorized vehicle from Maninjau (the village!) or tackle the path climbing from Bayur to Puncak Lawang, where the view is... top (yes, same name as the village).

HARAU VALLEY: 3 days
Magnificent rice terraces surrounded by towering cliffs and cascading waterfalls. That’s what awaits the adventurer—happy like Ulysses after a long journey to the fertile Harau Valley. It’s peaceful, off the beaten path, and rejuvenating.
Few tourists here, and few accommodations. The well-known Abdi Homestay offers quiet bungalows, slightly set back from the main road, in a stunning setting.
Again, renting a scooter is a great idea, but here, "happiness is in the fields"—well, the rice terraces. So, park your two wheels and venture along the paths crisscrossing the terraces, following small streams, brushing past villages lost in the valley. If you want to know more and see all the photos, it’s here: Harau Valley.

BEACHES SOUTH of PADANG: 4 days
20 km south of Padang lies Bungus Beach. But that’s not it yet... You’ll need to take a fisherman’s boat for 40 minutes south to land on a peninsula inaccessible by car. That’s the minimum to reach this little paradise, nestled between jungle and sea, far from Padang’s pollution and hustle. An Eden on an isolated beach, with nothing but small bungalows and possible excursions to the nearby islands. The only way to get around: by boat and on foot... Pure bliss, toes in the water. And on the blog "Un tour dans le sac", nothing is spared—especially not the description to make your mouth water (Indian Ocean water, that is): sublime turquoise waters, postcard-perfect coconut trees, lazing in your favorite hammock.

For the practical side, here’s some info:
Sumatra Travel: Itinerary Summary
My thoughts
Sumatra is a magnificent Indonesian island and still relatively untouched. Tourists mainly flock to Java and Bali. It’s especially suited for nature lovers who’ll appreciate its volcanoes, paradise islands, jungle, and rice terraces. Sumatra is huge: in 3 weeks, we only visited the northern half of the island... And even then, we barely scratched the surface of this stunning part of Sumatra. That said, this itinerary offers an exceptional variety of landscapes: beaches, volcanoes, rice terraces, jungle—the winning combo!
Overall, Sumatra is still lacking in infrastructure, and maybe that’s a good thing: it’s far from Bali’s rampant "hotel urbanization." That said, you’ll have to accept spartan comfort: Sumatra, as beautiful as it is, is only for backpackers, adventurers, and travelers who can do without cozy 3-star hotels. In short, Sumatra is earned, but the effort is well worth it, and the warm welcome from the locals will make you forget the minor travel inconveniences.
A disappointment? The food isn’t as good as Bali’s (check out our article on the subject (link)). The stop in Berastagi is nice but not essential, especially if you’ve already seen Java’s impressive volcanoes.
A favorite? There were so many! But if I had to choose, I’d pick the Ketambe jungle. It was my first experience in a natural environment I didn’t know: a primary forest and memories that’ll last!
Would I do the Sumatra trip again? I regret not going to the Mentawai Islands. This archipelago, off Sumatra’s west coast, has long remained isolated: some inhabitants still live traditionally. These "flower men" live in harmony with nature. Unfortunately, their way of life is threatened by modern influences, and their fragile, unique culture risks disappearing. I would’ve loved to spend time with this incredible ethnic group. But it takes time: a week seems necessary. I would’ve had to skip some stops in our itinerary—maybe the peninsula south of Bungus and Berastagi?
Budget:
It’s really cheap, especially the food, which, let’s be honest, isn’t amazing. Backpackers who can settle for spartan comfort (small bungalows without AC or hot water) and local food in warungs can easily get by on 20 € per day for two people (food + lodging). The cost of flights from Europe to Sumatra remains high. For our part, we found great deals on Paris-Hong Kong tickets (350 € round trip). Then you just need to reach Medan by low-cost airline.
No mandatory tipping in restaurants or accommodations. However, it’s more common to tip guides or taxi drivers.
Like many places in Indonesia, everything is negotiable. If you’re new to this, it’s not easy at first... Especially when dealing with a population poorer than us, "rich Westerners." But bargaining is part of the local culture! And you’ll get used to it—it even becomes fun. Plus, you don’t want to be that tourist paying the "tourist price" they’ll likely quote first, right?
To negotiate, be firm, respect your counterpart, smile, stay polite... Clearly show it’s too expensive or that the deal is done (by shaking hands, for example). Typing the numbers on your phone helps communicate the price. Learning a few words in the local language ("It’s too expensive," "How much?") is appreciated! Okay, it’s a rough tip, but here’s a base: dividing the first price by 2 gets you close to a fair negotiation.
Currently, 15,000 Indonesian rupiahs are worth about 1 €.
Accommodation
Infrastructure is underdeveloped in Sumatra. You’ll find fewer "charming lodgings" than in Bali. Still, there are some very pleasant places. If you read our Sumatra articles, we recommend Abdi Homestay in Harau Valley and Silimalumbo at Lake Toba. In Pulau Weh, the choice is wider, but we suggest trying the seafood pasta at Bixio Café!
Health
We didn’t get sick in Sumatra. By following a few simple rules (avoiding tap water, not swimming in stagnant freshwater), you’ll avoid the main issues. Hygiene is improving anyway. Anti-malaria treatment is still recommended, but cases are rare.
Also, keep in mind that Sumatra has a hot, humid climate—adjust your behavior accordingly (stay hydrated, protect yourself from the sun, etc.).
