About This Route

The Khao Sok to Koh Samui route connects Thailand's oldest rainforest national park with the Gulf of Thailand's premier island resort. This combo journey takes approximately 4 hours, with an air-conditioned bus from Khao Sok to Donsak Pier followed by a high-speed ferry to Samui. Khao Sok National Park is a must-visit destination known for its ancient rainforest, dramatic limestone karsts, Cheow Lan Lake, and diverse wildlife including gibbons, hornbills, and the rare Rafflesia flower. Many travelers combine a Khao Sok jungle stay with Koh Samui beach time. Lomprayah is the primary operator on this route, with pickups from hotels in Khao Sok town. The bus portion takes about 2 hours to Donsak, then the catamaran crosses to Nathon Pier in about 1.5 hours.
