Spend the day exploring the incredible Koh Surin National Marine Park, one of Thailand’s prime island locations, with this day-long speedboat retreat. This adventure will take you to the park’s two main islands, Koh Surin Nua and Koh Surin Tai, which form the bulk of the land, as well as three smaller islands.

Home to shallow coral sites, this park has some spectacular snorkelling opportunities, with a fringing reef that runs along the entire eastern edge of the islands and numerous boulder sites on the western side. Spend the day exploring the incredible plant and wildlife both on the islands and under the sea, and be sure to mix in some relaxing beach time in your day, before returning to your hotel in the late afternoon.
