Koh Lanta Beaches Guide: Which Beach to Choose

How Koh Lanta’s beaches work

The island’s swimmable beaches are all on the west coast, running roughly 18km from Saladan in the north to the national park in the south. A single road connects them all, making it easy to sample different beaches by scooter. The further south you go, the less developed and the more scenic the beaches become — at the cost of having fewer amenities and a steeper access road.

North (Klong Dao to Long Beach)

Klong Dao Beach

The main beach — 3km of gentle sand at the northern end of the island, 10 minutes from Saladan pier. The most developed beach on the island: a full range of guesthouses, restaurants, and beach bars behind the sand, sunbed hire available, and reliable facilities. The beach is wide and the swimming is safe in the dry season.

The northern end (closest to Saladan) is sandier and cleaner. The southern end transitions into the next beach (Klong Muang).

Right choice for a first Koh Lanta visit or anyone who wants all facilities within easy reach.

Long Beach (Phra Ae Beach)

4km south of Klong Dao. Slightly narrower than Klong Dao but quieter. A mix of budget bungalows and mid-range guesthouses along the beach road. Good swimming. The 7-Seas diving school and some of the island’s best casual restaurants are here.

Middle (Klong Nin to Nui Bay)

Klong Nin Beach

Roughly halfway down the island. A medium-sized beach with a different atmosphere to the northern beaches — calmer, fewer tourists, and a better position for sunsets. The road behind runs through local village rather than resort strip. Several independent restaurants and a handful of guesthouses. The beach is narrower at high tide.

A good choice for those who want a quieter beach but don’t want to commit to the steep south roads.

Nui Bay (Ao Nui)

A small bay between Klong Nin and Kantiang. The access road has hairpin turns — manageable by scooter, not in a standard car. The beach is short but the water is clear and the setting (limestone formations at each end) is attractive. A single guesthouse on the beach.

South (Kantiang Bay to Bamboo Bay)

Kantiang Bay

Widely considered the most beautiful beach on the island. A curved bay with clear water, limestone formations framing each end, and dense vegetation behind. The access road is steep (6km of switchbacks from the main road). Worth the effort. Two resorts occupy the bay; otherwise the beach is quiet.

The snorkelling at the southern rocky point is some of the best accessible from shore on the island.

Bamboo Bay (Ao Mai Pai)

Just before the national park boundary. A small cove with no facilities beyond one food shack. The access road is very steep and rough in places — best by motorbike, not suitable for most cars. The beach is narrow but the water is exceptionally clear. Completely isolated on weekdays.

Practical swimming notes

• All west coast beaches face the Andaman and are swimmable November to April
• The dry season sea is calm; low season (May–October) brings swell and occasional red flag conditions
• At low tide, some of the northern beaches (Klong Dao) expose sandbar — swim in the deeper central section
• Sunbed hire on Klong Dao: ฿100–150 per bed. The southern beaches have no hire infrastructure — bring your own towel
• Beach vendors operate on Klong Dao and Long Beach; the southern beaches have none
