Cut between karst islands, swim at Poda, cross the Tup sandbar, and relax on Railay Beach on a brisk five-hour speedboat loop from Krabi. This half-day tour mixes snorkeling, beach time and a short cave visit for a compact taste of the Andaman coast.
More ways to explore the area's outdoor wonders
The morning air tastes of salt and diesel as the speedboat cuts a bright line across the Andaman Sea. Limestone cliffs loom, their faces scored by monsoon rain and the slow work of coral, while small islands sit like cut gemstones in the turquoise water. You hop out for a swim at Poda, tread the shifting sandbar at Tup Island, and watch Chicken Island’s jutting roost of rock change color with the sun.

History
The karst coastline formed over millions of years from uplifted limestone and ancient coral; local communities historically relied on fishing and small-scale agriculture before tourism expanded.
Conservation
Reefs around the islands are sensitive—avoid touching coral, use reef-safe products, and minimize single-use plastics to reduce impact.

Bring reef-safe sunscreen
Coral here is fragile—use biodegradable, reef-safe sunscreen and reapply in shade to reduce runoff into the water.
Secure motion-sickness remedies
Open-water crossing can be choppy; take pills or wristbands before boarding if you’re prone to seasickness.
Protect your feet for sandbars
Tup Island’s sandbar is shallow and hot; water shoes or light sandals protect against sun-heated sand and sharp shells.
Follow snorkel safety briefings
Stick with the group, avoid touching coral, and surface slowly to conserve energy for the return ride.
Snorkel mask (or set)
A well-fitting mask improves underwater visibility and comfort during short snorkel stops.
Reef-safe sunscreen
Protects skin and prevents harmful chemicals from damaging coral ecosystems.
Light windbreaker or rashguard
Shields against spray and wind on the open crossing and doubles as sun protection.
Water shoes
Useful for walking sandbars and rocky shorelines without cutting feet.
