Board a day-and-night boat from Krabi for snorkeling across seven islands, a sunset buffet on Poda, and a surreal night swim among bioluminescent plankton at Koh Raeng. Expect limestone cliffs, sandbars at low tide, and calm-water snorkel spots.

The boat slips away from Ao Nang as late afternoon light gilds sheer limestone cliffs; salt smells of the Andaman press against your skin and the sea dares you to dive in. Over the next seven hours you’ll hop from coral-strewn snorkeling sites to a widening sandbar that links Tup, Mohr and Chicken Islands, watch the sun set behind Poda’s cliffs while a buffet waits, then wade into warm ink-black water to see bioluminescent plankton flare around your hands like captured stars.

The boat slips away from Ao Nang as late afternoon light gilds sheer limestone cliffs; salt smells of the Andaman press against your skin and the sea dares you to dive in.

These limestone islands are fragments of a much older marine landscape carved by tectonic uplift and tropical weathering—karst towers rising from shallow continental shelf. Locals have long fished and rowed between these outcrops; today small charter boats are the practical way to access reefs and sandbanks that appear and vanish with the tide.
Expect coral gardens in shallow reefs, schools of butterflyfish, and a sandbar that’s best explored at low tide. The night swim at Koh Raeng is weather- and plankton-dependent—clear, calm seas and minimal light pollution turn the biolume vivid; windy or choppy nights dim the effect.
Practicalities: the trip is a 7–8 hour shared boat tour with round-trip transfers from Krabi/Ao Nang, life vests, and a buffet dinner on Poda Island. Bring reef-safe sunscreen, a waterproof light, a light jacket for sea breeze, and a dry bag for electronics. Plan on moderate sun exposure and some short swims and wading; photographers should guard gear against spray. If you prioritize safety and stewardship—respecting coral and minimizing plastics—you’ll leave with memories of bright reef life by day and a glowing, otherworldly sea by night.
easy.
7–8 hours.
Suitable for most people who can swim short distances and climb laddered boat entry points; minimal sustained exertion required.
The excursion lasts about 7–8 hours and typically stops at seven island locations including Ko Ya Wa Sam, Ko Mor, Tup, Chicken, Poda, Ko Ma Tang Ming, and Koh Raeng for the plankton swim.
Yes—life vests are provided and guides supervise the plankton swim; non-swimmers should wear a vest and stay near the boat or shallower water.
Calm, warm nights with little moonlight and minimal boat lighting provide the strongest bioluminescent displays; windy or choppy nights reduce visibility.
The tour includes snorkel masks, life vests, and complimentary round-trip transfers from Krabi Town and Ao Nang; bringing personal masks and fins is optional.
These islands are part of the Andaman shelf; their karst cliffs formed from uplifted marine limestone and supported coastal fishing communities for generations.
Coral reefs here are sensitive—avoid touching or standing on coral, use reef-safe sunscreen, and pack out all plastics to minimize impact.
