About Koh Ngai (Koh Hai)

- Activity
- Snorkeling from the beach.
- How you get into the water
- Yes, along parts of the east coast and at the southern beaches such as Paradise Beach.
- Under water
- Coral blocks and a variety of reef fish. Not the whole main beach is equally interesting.
- Good to know

- Access now
- No separate, current guarantee of access was found; check local access and conditions on the spot.
