13 Best Things to Do in Koh Lanta: Beaches, Attractions & Island Activities

Koh Lanta is the laid-back island of Krabi province. It has long quiet beaches, jungle waterfalls, caves, an old fishing town on stilts and some of the best snorkelling day trips in the Andaman Sea.

It's also a comfortable choice for Malaysian travellers, since most locals are Muslim and halal food is easy to find. Here are 13 of the best things to do on Koh Lanta, each with prices and a map link.

1Relax on Klong Dao Beach

Klong Dao is about 3 km from Saladan pier and the most popular beach on Koh Lanta. The water is calm and shallow, which makes it ideal for families with young children.

There are plenty of hotels, restaurants and beach bars along the sand. When the waves are good, you can even try surfing.

2Walk the sands of Long Beach (Phra Ae)

Long Beach stretches for nearly 4 km of fine sand, about 7 km from Saladan pier. It has the widest swimming strip on the island and the biggest choice of restaurants.

It's a good base if you want beach time and easy dining in one place.

3Watch the sunset at Kantiang Bay

Kantiang Bay is a crescent-shaped bay about 25 km from the pier, in the quieter south. It's large, sandy and calm. It's also known for its sunsets.

The road down is steep, so ride carefully if you're on a scooter.

4Find peace at Bamboo Bay

Bamboo Bay (Ao Mai Pai) is a wild, jungle-backed beach near the southern tip. One travel writer counted fewer than 10 people there. It's the place to go when you want a beach almost to yourself.

As a rule, the further you get from the port, the quieter the beaches become.
