Koh Lanta's beaches line the west coast of Koh Lanta Yai, and they change from north to south. The north, around Klong Dao and Long Beach, is flatter, busier and easiest for families; the south, from Kantiang Bay to Bamboo Bay, is hillier, quieter and wilder. Every one of them faces west, so every one gets a sunset.
The Tourism Authority of Thailand counts nine sandy beaches on Lanta Yai, an island more than 30 km long and about 6 km wide. A single road runs down the west side, and the farther south you go, the steeper and more winding it gets. That road, more than the sand, is what separates the "easy" beaches from the remote ones.
Which beach suits you depends on three questions: do you want to walk to restaurants, do you have small children, and are you coming in the dry season or the monsoon? The sections below go from north to south.
Lanta's west coast in brief
- North (Klong Dao, Long Beach)
- Flat, long, many hotels and restaurants, closest to Saladan pier
- Middle (Klong Khong, Klong Nin)
- Smaller, mixed rock and sand, a step quieter
- South (Kantiang to Bamboo Bay)
- Bays between headlands, hilly road, few shops
- Smoke-free beaches
- Klong Dao and Phra Ae (Long Beach) were among the 24 beaches where smoking was banned from 2018
- Best sea
- Roughly November to April; the southwest monsoon brings waves and red flags from about May to October
Klong Dao: the easy family beach
Klong Dao (Khlong Dao) is the first long beach south of Saladan, the village where boats arrive. TAT lists Hat Khlong Dao among Lanta's highlights. The sand is wide and the slope into the water is gentle, which makes it one of the more comfortable places to swim with children in the dry season.
It is also the most convenient beach. Saladan's banks, clinics, shops and pier are a short ride away, and there is a full range of hotels and family resorts along the sand. The downside is that Klong Dao feels developed. If you want a lonely beach, this is not it.
Who it suits: families, first-time visitors, short stays and anyone without a scooter.
Long Beach (Phra Ae): the longest stretch and the most choice
Phra Ae, known to most visitors as Long Beach, follows directly south of Klong Dao and is the longest and busiest beach on the island. TAT names Hat Phra Ae as one of Lanta's main beaches. It has the widest choice of places to stay, from simple bungalows to resorts, plus beach bars, restaurants, massage places and the shops along the road behind it.
The beach is long enough that it never feels crowded on the sand, even when the road behind is busy. The northern end is quieter and more resort-like; the middle has the bars that give Lanta its small, low-key nightlife. Nothing here compares with Phi Phi or Patong.
Who it suits: couples and solo travelers who want choice, a few bars and long walks at sunset, and families who want something livelier than Klong Dao.
Klong Khong and Klong Nin: the middle coast
South of Long Beach, the coast becomes rockier. Klong Khong has a mix of sand and rocks, so check the tide before you swim; the water is easier when it is high. It has a relaxed backpacker feel, with simpler bungalows and beach bars.
Klong Nin is one of the nicest swimming beaches in the middle of the island, with soft sand and a small village behind it. It is a good compromise: quieter than the north, still with restaurants and shops within walking distance, and a road across the island to the east coast and the Old Town.
Who it suits: travelers who want a quieter beach without giving up a choice of places to eat, and longer stays where you want a bit of village life.
Kantiang Bay: where the wild south begins
Beyond Klong Nin, the road climbs over headlands and the scenery changes. Kantiang Bay is a deep, curved bay backed by forested hills, with a small village and a handful of resorts. It is widely regarded as one of the most beautiful bays on Lanta, and in the dry season the water is clear and calm.
Life here is quieter and more self-contained. There are restaurants in the village, but for anything more you need transport, and the road north is steep in places. A few smaller coves nearby, such as Ba Kantiang, are reached by short tracks or through resorts.
Who it suits: couples and anyone who wants scenery and peace but still likes a choice of a few restaurants.
Klong Jark and Bamboo Bay: near the end of the road
Klong Jark is a small, quiet beach near the southern end of the island, with a few bungalows. Bamboo Bay (Mai Pai) is the last bay before the national park, a sheltered crescent with a handful of places to stay and the feeling of being at the end of the island, which you nearly are.
These two are the wildest beaches you can reach by road. Forest comes down to the sand, evenings are dark and quiet, and a trip to a supermarket or an ATM is a real outing. The road down is steep and winding; ride it slowly, and not in heavy rain. Our guide to riding a scooter safely in Thailand is worth reading before you rent one here.
Just beyond Bamboo Bay are the park headquarters, Ta Nod beach and the lighthouse; see our guide to Mu Ko Lanta National Park.
Who it suits: people who want to switch off completely, with their own transport.
| Beach | Area | Feel | Families | Walk to restaurants |
|---|---|---|---|---|
| Klong Dao | North | Developed, calm | Very good | Yes |
| Long Beach (Phra Ae) | North | Busiest, a few bars | Good | Yes |
| Klong Khong | Middle | Laid-back, rocky | Fair | Some |
| Klong Nin | Middle | Village, quieter | Good | Yes |
| Kantiang Bay | South | Scenic, peaceful | Good in the dry season | A few |
| Klong Jark | South | Remote, small | Fair | Few |
| Bamboo Bay (Mai Pai) | South | End of the road | Fair | Few |
Sunsets: every beach, but some do it better
Because the whole coast faces west across the Andaman Sea, you can watch the sun go down from any of these beaches between roughly November and April, when skies are clearest. Long Beach is the classic choice for a sunset walk, with bars at the water's edge. Kantiang Bay and the headlands to the south add hills and islands to the view. The lighthouse viewpoint at Laem Tanot is another, but the park day ends at about 16:30, so you see the light rather than the sunset itself there.
Swimming in the low season
Lanta changes in the southwest monsoon. Rainfall at nearby Krabi is highest from May to October, peaking in September and October, according to the Thai Meteorological Department's 1991–2020 averages. Onshore wind brings waves and strong currents to the west-facing beaches, and the UK Foreign Office warns that people have drowned in riptides in Thailand, especially in the monsoon.
- Follow the flags. A red flag means no swimming. Lifeguards are not on every beach.
- Choose sheltered spots. Bays between headlands can be calmer than long open stretches, but no beach is safe in a storm swell.
- Watch for stingers. On 5 June 2026, park staff found Portuguese man-of-war washed up at Laem Tanot and banned swimming there.
- Expect fewer services. Boat trips to the outer islands of the national park stop for the monsoon; check that your hotel and the restaurants you want are open.
Monsoon surf hits Lanta's west-facing beaches head-on. On rough days between May and October, the waves come straight onto the beach. If locals and lifeguards are not swimming, do not swim either, however inviting the water looks.
Our guides to rip currents and beach flags and jellyfish in Thailand explain what to do. For the trade-offs of traveling in the wet months, see the page on Thailand's rainy season, and the best time for the Thai islands compares the Andaman and Gulf coasts.
Beyond the beaches: the east coast
The east coast faces the mainland and has mangroves rather than swimming beaches. It is worth a half-day trip for Lanta Old Town (Baan Si Raya), the island's administrative center, with wooden houses on stilts and the post office, and for the Sea Gypsy (Urak Lawoi) village of Baan Sangka U, both listed by TAT. Our Koh Lanta guide covers the rest of the island.
Still getting there? Our guide to Krabi to Koh Lanta compares the road route and the boats; all boats land at Saladan, a short ride from Klong Dao. For day trips from Lanta, the guide to the Trang islands covers Koh Ngai, Koh Mook and Koh Kradan. If you are still choosing between islands, our guide to which Thai island suits you puts Lanta next to the others, and the Phi Phi guide shows what a busier island next door is like.
Frequently asked questions
What is the best beach on Koh Lanta for families?
Klong Dao is the usual choice. The sand is wide, the water shelves gently, and it is close to Saladan's shops and clinics. Long Beach and Klong Nin also work well. In the dry season, Kantiang Bay is calm and very pretty, but more remote.
Which part of Koh Lanta is the quietest?
The south, from Kantiang Bay to Klong Jark and Bamboo Bay. The road is hilly, there are few shops, and nights are dark and quiet. You will want a scooter or car, because there is little within walking distance.
Can you swim on Koh Lanta in the rainy season?
Sometimes. On calm days the sea is fine, but from about May to October the west coast often has waves and strong currents. Swim only where there is no red flag, preferably near lifeguards, and stay out of the water in rough weather.
Is Long Beach on Koh Lanta a party beach?
Not in the Phi Phi or Koh Phangan sense. Long Beach has the island's liveliest bars, but most evenings are relaxed, and you can easily find quiet stretches along the sand.
Is smoking allowed on Koh Lanta's beaches?
Klong Dao and Phra Ae (Long Beach) were on the 2017 list of 24 Thai beaches where smoking was banned, with designated smoking areas behind the beach. Penalties are heavy, so use those areas and do not leave cigarette butts in the sand.
