Koh Lanta beaches line almost the whole west coast of Lanta Yai, one after another from Saladan in the north to the national park in the south. They all face the sunset, but each has its own character: long and flat, busy with bars, rocky and quiet, or tucked into a jungle cove. Choosing the right one matters, because on Lanta your beach is usually also where you stay.
This guide ranks the best Koh Lanta beaches from north to south, with notes on swimming, crowds, facilities and who each one suits.
Top picks: Klong Dao for families, Long Beach for restaurants and bars, Klong Khong for sunsets, Klong Nin for calm, and Kantiang Bay or Bamboo Bay for scenery.

All Koh Lanta beaches are free and public. Sea conditions change with the season: from May to October, waves and currents can make swimming unsafe, so follow local flags and advice.
Klong Dao
The first long beach south of Saladan. It is wide, flat and very gently sloping, with calm water in the dry season. Resorts line the sand and restaurants are close by. Among Koh Lanta beaches, it is the easiest for families with small children.
Long Beach (Phra Ae)
The island’s busiest beach, several kilometres long, with the most restaurants, bars and bungalows. Swimming is good, the sand is soft and sunsets draw everyone to the water. It is lively but not wild.
Klong Khong
South of Long Beach, Klong Khong has a backpacker feel, beach bars with cushions on the sand and some of the best sunsets on the island. At low tide the rocks are exposed, so swimming is better at high tide.
Klong Nin
A long, quiet beach with a mix of resorts and small local restaurants. It is popular with couples and longer stays, and swimming is good when the tide is in.
Kantiang Bay
A sheltered bay in the south framed by green hills, with soft sand and clear water in the dry season. It is quieter and more scenic than the northern Koh Lanta beaches, and home to a few upscale resorts and a small village.
Bamboo Bay, Klong Jak and the Far South
Further south, Klong Jak hides behind a jungle road, Bamboo Bay is a small, peaceful cove near the national park, and the park’s own beach sits below the lighthouse. Roads here are steep; go by taxi if you are not a confident rider.
What About the East Coast?
The east coast faces the mainland and is lined with mangroves and fishing villages, including Old Town. It is fascinating for kayaking and culture but has no swimming beaches to compare with the west. See things to do in Koh Lanta.
Choosing a Hotel on Your Beach
Because the beaches are spread out, your hotel decides where you swim most days. Read where to stay in Koh Lanta for hotels by beach.

Koh Lanta Beaches by Type of Traveller
| You are… | Go to |

Most Koh Lanta beaches are a short taxi or scooter ride apart, so you can sample several in a few days even if you stay in one place.
Koh Lanta Beaches by Season
From November to April, the sea is usually calm and clear, and all Koh Lanta beaches are pleasant for swimming. From May to October, the south-west monsoon brings waves, rip currents and more rubbish washed ashore; swimming can be dangerous and many beach bars close. Southern bays like Kantiang are more sheltered but still affected. Always check the flags and ask your hotel about conditions.
Tides Make a Difference
Tides shape the beaches more than visitors expect. At low tide, Klong Khong and parts of Klong Nin reveal rocks and pools that make swimming awkward but are fun to explore; at high tide the water comes close to the sand and swimming is easy. Klong Dao and Long Beach are flatter and less affected. Check a tide app before planning a swim on the rockier Koh Lanta beaches.
Beach Safety
- Swim between flags where they exist and avoid swimming alone.
- Watch out for rip currents in the monsoon season.
- Jellyfish can appear at certain times; ask locally and use vinegar for minor stings.
- Keep valuables out of sight on quiet beaches.
- Do not ride a scooter on the steep southern roads if you are inexperienced.
A Beach-Hopping Day
Rent a scooter or hire a taxi for the day and work south: morning swim at Klong Dao, lunch on Long Beach, an afternoon at Kantiang Bay, then back north for sunset at Klong Khong. It is a simple way to see the best Koh Lanta beaches in one go.
Facilities
The busier beaches have sunbeds, restaurants, massage huts and minimarts. Quieter ones may have one restaurant or nothing at all, so bring water and shade.
Beaches Beyond the Main Island
Some of the most beautiful sand near Lanta is offshore. Koh Rok has powdery white beaches and reef right off the shore; Koh Ngai, to the south-east, has a long beach backed by forest; and the islands of the Trang coast, visited on the 4 Islands tour, include Koh Kradan with its clear shallows. These are day trips rather than places to swim every day, but they are worth adding to your list of Koh Lanta beaches.
Respecting the Beaches
- Take your rubbish with you; bins are scarce on quiet beaches.
- Avoid single-use plastic and straws at beach bars.
- Do not remove shells or coral.
- Keep music low on quiet coves.
Many hotels and local groups organise beach clean-ups, especially after the monsoon. Joining one for an hour is a good way to give back to the island.
Best Koh Lanta Beaches for Photos
For sunset photos, Klong Khong and Long Beach are the classic spots, with longtails and silhouettes against the sky. For turquoise water and green hills, try Kantiang Bay from the viewpoint on the road above it. The rocky headland at the national park makes a dramatic subject in the late afternoon. Bring a polarising filter to cut glare on the water, and visit in the dry season when the sky is clearest.
Getting Between the Beaches
There is one main road down the west coast. Taxis and motorbike sidecars can be arranged through hotels, and scooters are rented everywhere. Agree taxi prices in advance, especially for the far south.
