More ways to explore the area's outdoor wonders
The day begins before the sun climbs fully above the Andaman — you step onto Saladan Pier as a low hum of engines and seagulls sets the rhythm. A modern speedboat cuts through glassy water, leaving Koh Lanta’s palms behind and steering toward a ring of limestone and coral: Koh Haa’s lagoon first, then the twin beaches of Koh Rok.

History
These islands sit along long-standing Andaman Sea trade routes; local communities on Koh Lanta blend Malay-Muslim and Moken influences with fishing traditions.
Conservation
Mu Ko Lanta National Park limits development and enforces no-anchoring zones; visitors should use reef-safe products and avoid contact with coral to minimize impact.

Bring a snug mask or rent one
A well-fitting mask reduces fogging and lets you stay in the water longer; rentals are available but bring your own if you have one.
Use reef-safe sunscreen
Apply mineral-based sunscreen before boarding to protect coral reefs and avoid reapplying in the water.
Mind the currents
Snorkel close to the guide in channels where currents can pick up; ask for short laps if you’re less confident in open water.
Protect photos with a case
Bring a waterproof case or GoPro—underwater visibility rewards cameras, but saltwater is unforgiving to electronics.
Snorkel mask (fit-tested)
Reduces fogging and improves visibility during multiple snorkel stops.
Reef-safe sunscreen
Protects skin and fragile coral ecosystems under tropical sun.
Waterproof camera or case
Captures reef life and island vistas without risking your phone.
Light water shoes
Useful for rocky shores, quick hikes to viewpoints, and beach walks between sand and reef.
