Ratchaburi is the province where a single valley became western Thailand's camping capital. Nearly every pitch sits along the Suan Phueng–Ban Kha corridor, following the Phachi river and the Tenasserim foothills on the Myanmar border — mountain atmosphere about two and a half hours from Bangkok, no drive north required.
Prices are among the friendliest anywhere — mostly ฿100–200 per person per night — with everything from bare pitches to made-up tents with an on-site cafe, so it serves both budget and comfort trips.

Suan Phueng is the livelier side — cafes, restaurants and daytime landmarks, with many neatly laid-out grounds. Ban Kha, deeper south, is quieter and darker, with clearer stars; campers after the rawer feel tend to continue there. The two sides hold near-equal numbers of camps, so pick by temperament.
Late rains into winter is this valley's peak: November to January brings cool nights and frequent morning mist — book ahead for Saturdays and long weekends. Hot-season days are hot but mountain air keeps nights tolerable; in the rains the valley turns deep green and the Phachi runs strong, so favour pitches set back from the bank.
Valley roads mix climbs and bends; sedans reach nearly every camp, but allow time and avoid night driving if you're new to it. The last big fuel stop is around Suan Phueng town — fill up before continuing into Ban Kha.
Mostly ฿100–200 per person per night; made-up tent packages step up with the comfort level.
Nights get genuinely cool to cold in December–January — bring a sleeping bag and a warm layer.
Yes — many grounds on both sides rent tents and bedding; check each camp's listing on this page.
