Your guide will accompany you on the longtail boat, where you’ll enjoy the gentle, sometimes bumpy, sail across the waters.

Koh Chueak Island: Snorkeling and Sea Caves

After about 45 minutes, you’ll arrive at Koh Chueak, a diamond-shaped island famed for its sea caves and clear waters. The caves are a highlight—swimming through dark tunnels to emerge into a hidden lagoon, as many reviewers experienced. One reviewer, Kate, described the guides as “lovely and attentive,” with guides often snorkeling alongside guests to point out interesting marine life.

The snorkeling here is a mixed experience, with some noting the small coral reefs and murky water as less than ideal. As Jamie pointed out, the visibility can be poor with some reefs only offering limited marine life. However, the thrill of swimming through caves and exploring the underwater scenery still makes it worthwhile.

Koh Mook and the Emerald Cave

Next is the famous Emerald Cave on Koh Mook. Swimmers prepare to enter pitch-dark tunnels, swimming several meters to emerge into a lush, green lagoon with a sandy beach. It’s a surreal experience, and reviewers like Michaela highlight the caves as astonishing. Be prepared to get wet—this involves swimming through water tunnels, sometimes with waves, so a waterproof bag and water shoes are recommended.

The Emerald Cave attracts many because of its unique combination of adventure and natural beauty. You’ll likely share this spot with other tour groups, but the sense of discovery makes up for the crowds. Once inside, the lagoon feels like a secret world—a well-preserved highlight praised by many.

Koh Ngai: Beachside Lunch and Relaxation

After the cave adventure, the boat cruises to Koh Ngai for a Thai buffet lunch served on a picturesque beach. The meal includes rice, fried vegetables, massaman chicken curry, and fresh fruit, and reviews mention the unexpectedly good quality of the food—a pleasant surprise considering the remote location.

The beach here boasts white sands and clear waters, perfect for relaxing, sunbathing, or strolling along the shoreline. One reviewer, Hannah, noted she felt really comfortable and enjoyed the views—a perfect spot to recharge before more water fun.
