Dusk paints the limestone towers gold as a longtail boat slips out of Nopparat Thara Pier, the engine’s thrum blending with seabirds and the distant call of local fishermen. You glide past limestone cliffs and clear shallows, stopping at shallow coral gardens where the water is warm and the reef life is bold enough to inspect your mask.

Dusk paints the limestone towers gold as a longtail boat slips out of Nopparat Thara Pier, the engine’s thrum blending with seabirds and the distant call of local fishermen. You glide past limestone cliffs and clear shallows, stopping at shallow coral gardens where the water is warm and the reef life is bold enough to inspect your mask.
This stretch of the Andaman Sea is defined by karst geology — vertical limestone cliffs carved over millennia — and small sandstone and coral islets like Koh Kai (Chicken Island), Koh Tub, Tup Islets and Poda. The islands sit close to communities that have fished and guided visitors for generations, and the longtail boat itself is a cultural icon, hand-built and tuned for these waters.
Expect a mix of shallow snorkeling over sandy flats and coral patches, a low-tide sandbar walk between Tup and Mor that feels like crossing the sea on a ribbon of sand, and a beachfront buffet at Poda Island as the sun lowers. After dinner, the boat takes you to seek the faint blue of bioluminescent plankton — brief, magical flashes against black water.
Practicalities: meet at Nopparat Thara Pier at least 30 minutes early; the tour runs about seven hours. Snorkel gear and life jackets are provided, but bring reef-safe sunscreen, a waterproof bag, water shoes for the sandbar, and a light cover-up for the evening breeze. The monsoon (roughly May–October) brings rougher seas and more jellyfish; guides may change the route for safety. Stay aware of tide timing for the sandbar walk and follow crew instructions during night snorkeling.

Local fishing communities and sea gypsies have used longtail boats for generations; the karst islands have long guided mariners and supported small coastal settlements.
The Andaman reef systems are sensitive to anchors and sunscreen chemicals; choose operators who use mooring buoys and encourage reef-safe practices to minimize impact.
