Two fee zones — which one do you pay?
Khao Sok is in DNP rate group 2. The main park HQ area (Phanom District) uses the standard rate of 200 THB for foreign adults. The Ratchaprapha Dam / Cheow Lan Lake zone has been a designated special-fee area since 1 May 2024, so most lake visitors pay 300 THB for adults (150 THB for children). Both zones charge the national park entrance fee separately from boats, raft houses and tours.
- ▪ Park HQ & jungle trails (Phanom) — 200 / 100 THB for foreign visitors
- ▪ Cheow Lan Lake / Ratchaprapha Dam (Ban Ta Khun) — 300 / 150 THB for foreign visitors
- ▪ Thai nationals — 40 / 20 THB in either zone
