Jump on the ecotourism bandwagon and go ‘green’ for a day. Combining mountain and sea adventures, this full-day nature tour brings you a full-on expedition into the wilderness of Khao Sam Roi Yod National Park, about 30 minutes south of Hua Hin town. Literally meaning ‘300 peaks’, Sam Roi Yod is famous for its dense forest cover, limestone caves with dramatic light shafts, petrified waterfall and dangling stone tentacles.
