The main social activity centers around Sai Kaew Beach and the town of Na Dan, particularly in the evenings.

3. Beach Hopping by Scooter
Explore Koh Samet's diverse array of beaches and bays, ranging from the bustling Sai Kaew and Ao Phai to the more secluded Ao Prao, Ao Noi Na, Ao Nuan, and Ao Wai. Renting a scooter provides the flexibility to discover hidden coves, enjoy different atmospheres at various beaches, and find your own peaceful spot. The island is small enough to navigate easily.

4. Explore the Koh Samet Nature Trail and Southern Viewpoints
Hike along the designated nature trail that traverses the island's interior, offering a chance to observe the local forest environment, plants, and possibly some wildlife.

5. Try Water Sports (Jet Skiing or Kayaking)
Engage in a variety of water sports available on the island's popular beaches. For an adrenaline rush, jet skiing is offered at vibrant spots like Sai Kaew Beach. If a more serene exploration is preferred, kayaking and canoeing provide an eco-friendly way to paddle along the coastline, discover quieter bays, and enjoy the pristine waters at your own pace.
