Krabi 4-Island Sunset & Bioluminescent Plankton Private Long-tail Boat Tour
Board a private long-tail from Ao Nam Mao for a six-hour cruise to Koh Kai, Talay Waek, Koh Poda and Phra Nang. Snorkel coral gardens, watch a tropical sunset on a quiet beach and finish with a swim through glowing bioluminescent plankton.
The Experience
Before You Go
Use reef-safe sunscreen
Apply biodegradable, reef-safe sunscreen before boarding to protect coral and reduce the need for reapplication while snorkeling.
Bring a waterproof case
A waterproof phone case or small camera keeps sunset and plankton photos safe — but avoid bright lights during plankton viewing.
Wear water shoes for beaches
Beaches and shallow reef approaches can have rock or coral rubble; light water shoes make beach walks and entries safer.
Time with the moon
For the brightest plankton display, book around a new moon and choose a calm-sea evening to improve visibility.
Local Knowledge
Hidden Gems
- •Beach walk across the sandbar at low tide near Koh Poda
- •Sunset viewpoint just outside Phra Nang cave for quiet photos away from crowds
Wildlife
- •Parrotfish and wrasse on shallow reefs
- •Occasional long-tailed macaques near Phra Nang’s shoreline (observe from a distance)
Conservation Note
Avoid touching or standing on coral, use reef-safe sun products, and dispose of waste ashore — tourism pressure requires careful behavior to protect reefs and plankton habitats.
The Krabi coastline is defined by limestone karst formed from ancient marine sediments; the caves and stacks have long supported local fishing and small-scale trade communities.

Common Questions
Is the plankton swim safe for non-swimmers?
Yes — the tour provides life jackets and the plankton viewing is in shallow, calm water near the boat or beach; non-swimmers should wear a life jacket and stay close to the crew.
Do I need to bring my own snorkel gear?
Snorkelling equipment is included, but you may prefer to bring your own mask for fit and comfort.
When is the best time to see the bioluminescent plankton?
Plankton are most visible on dark, calm nights (ideally around a new moon) and when the sea is undisturbed by rain or heavy surf.
Is hotel pickup available?
Yes — free pickup and drop-off are typically provided for Ao Nang and nearby areas; confirm your pickup point at booking.
