I'm looking for my first stop fairly close to Bangkok (ideally a max of 2 hours' travel time), somewhere relaxing—maybe Samut Sakhon?
(...)
Want some nature, to visit one or two parks... which one...
I only know Samut Sakhon from its train station and the street you take to get to the ferry port—I didn’t realize it had any other appeal.
For a relaxing town within 2 hours max from Bangkok’s northern minivan* bus station or the train station, the city that’s generally—and rightly—recommended is Ayutthaya, which also has a lot to see. Plan to stay there for 2 to 3 nights.
From there, after a "short" train ride, you could head to Pak Chong to visit Khao Yai National Park in a day with a wildlife guide. Kids are welcome (and usually love it), and it’s easy to organize through the accommodations around the park. Plan for 2 nights at this stop.
Then, for example, about 2.5 hours by minivan* to Bangkok’s northern minivan station, and from there another 2.5–3 hours by minivan* to Kanchanaburi, a town with recent historical interest. In this province, you could spend a week visiting Erawan National Park, the temple whose name I always forget (a few km southeast of the town—see the 3 photos below). During this week, you could spend 1 or 2 nights in peaceful Thong Pha Phum, which will give you a sense of being at the end of the world (there are several spots to stop for an hour or two between Kanchanaburi and Thong Pha Phum). Then, of course, a 3rd stop in charming, peaceful Sangkhlaburi for 3–4 nights.
All these towns or villages offer accommodations and public transport to get there.
After Sangkhlaburi, take a bus** or direct minivan back to Kanchanaburi during the day, followed by a 55-minute air-conditioned bus 81 (every 20 minutes) in the late afternoon to Ban Pong, where you can catch an overnight train to any major southern station. Alternatively, if you spend one last night in Kanchanaburi and get up early***, you can take the Special Express DRC No. 43 daytime train to Prachuap Khiri Khan.
From the south, I only know the non-beach sites in Trang, Phatthalung, and Nakhon Si Thammarat.
For beach destinations, it’s best to wait for other members to chime in once you have specific questions.
*These minivans run frequently, every 2–3 hours. On minivans, luggage goes on your lap or you can pay for an extra seat (4–5 € per person for these routes) to put it there.
**There are 4–5 buses per day—these are regular buses, so the trip takes 5–6 hours.
***The Express DRC 43 leaves Ban Pong at 8:42 AM. It’s a 10–12 minute walk from the bus stop in Kanchanaburi to the train station.
If you have any links to help me visualize the routes (trains, ferries, flights), that would help me plan my itinerary—I’m struggling to find all this info.
For possible train routes, there’s no site that’s both comprehensive and available in English or French. Once you know your departure and arrival cities, you can use the official Thai train booking site: https://dticket.railway.co.th/DTicketPublicWeb/home/Home (change the language in the top right corner).
For ferries, search by destination. You should also find this info in the Lonely Planet guide.
Flights: This site https://www.airasia.com/en/gb covers most airlines. For Nok Air, go here: https://www.nokair.com/
Be careful in Bangkok—there are two airports: BKK (the main one, where you’ll arrive) and DMK. They’re not close to each other.
