Khao Sok to Koh Samui by Bus + High-Speed Catamaran

If you are exploring Khao Sok National Park and want to continue your journey to Koh Samui, Boonsiri Sealine provides a convenient combined land and sea travel option.

The Khao Sok to Koh Samui route operates as a Joint Ticket, connecting a land transfer from Khao Sok with a High-Speed Catamaran service to Koh Samui. This makes it easier to plan your journey from the rainforest of Khao Sok to the islands of the Gulf of Thailand.

The schedule and fare above are reference information for services available in September 2026. Always check the latest schedule and fare before booking, as operating times may change.

How to Travel from Khao Sok to Koh Samui

There is no ferry directly from Khao Sok because Khao Sok is located on the mainland. The journey therefore combines a land transfer with a high-speed ferry.

The general journey works as follows:

1. Meet the transfer service at the designated pickup point in Khao Sok.
2. Travel by road toward the Donsak area.
3. Connect with the ferry service.
4. Board the Boonsiri High-Speed Catamaran.
5. Continue by sea to Koh Samui.

With a Joint Ticket, travelers can plan the Khao Sok → Koh Samui journey as one connected trip instead of arranging separate road and ferry tickets themselves.

This makes it possible to combine two very different experiences in one trip: rainforest adventure in Khao Sok followed by a beach holiday in Koh Samui.
