Best Beaches on Koh Lanta: Where to Swim, Relax & Watch Sunset

Koh Lanta has a long coastline with plenty of beaches to explore, and they can feel surprisingly different.

The north is busier and more developed, while the beaches get quieter and more remote as you travel south.

I spent a week exploring Koh Lanta by moped and visited beaches all along the west coast.

Some were great for swimming and spending the day, while others stood out for their sunsets, scenery or peaceful atmosphere.

In this guide, I’ll share the best beaches in Koh Lanta, what you can expect from each one and which I think are actually worth visiting.

Quick Answer: What Are the Best Beaches in Koh Lanta?

If it’s your first time in Koh Lanta, Long Beach is my best overall choice. It’s easy to reach, has plenty nearby and works well for both swimming and sunset.

But the best beach really depends on what you’re looking for.

My tip: If you have your own transport, don’t choose just one. The west coast is easy to explore, and I’d spend at least one day beach-hopping from north to south.

Map of the Best Beaches on Koh Lanta

Most of Koh Lanta’s main beaches run down the west coast, becoming generally quieter and less developed as you travel south.

Use my map below to see where each beach is and plan your own beach-hopping route.

Best Beaches on Koh Lanta’s West Coast

Most of Koh Lanta’s main beaches are along the west coast. The north is more developed and convenient, while the beaches generally become quieter and more natural as you travel south.

Here are the beaches I think are most worth considering, starting with my best overall choice.

Long Beach – Best Overall Beach in Koh Lanta

Long Beach is the beach I’d recommend to most first-time visitors to Koh Lanta.

It’s long, easy to access and has enough restaurants, cafés and accommodation nearby to make it convenient without feeling too busy.

I stayed a short walk inland from Long Beach and found the location really practical. I could walk to the beach, restaurants and shops, then use a scooter when I wanted to explore farther around the island. 

The beach itself is good for swimming and works well for a relaxed afternoon, but I also liked it at sunset.

Because it’s so long, you can usually find a quieter stretch if you don’t want to sit near the busier access points.

My tip: Long Beach is a great choice if you want an easy beach day without giving up convenience. It’s also one of the best bases on the island if you don’t plan to rent a scooter every day.

Klong Dao Beach – Best for Families

Klong Dao is one of the easiest beaches to enjoy in Koh Lanta. It’s close to Saladan Pier, has plenty of restaurants and accommodation nearby, and the beach itself is long and spacious.

One of its biggest advantages is the gently sloping shore, which makes it a good choice for swimming and especially practical for families with children.

The wide sandy beach also gives you plenty of room, and there are trees providing shade along parts of the coast.

Despite being in one of the more developed parts of Koh Lanta, Klong Dao still feels relaxed.

It’s also a lovely place to stay for sunset, with views across the water towards the distant islands and limestone cliffs.

My tip: Klong Dao makes more sense as a beach to stay near and enjoy, rather than somewhere I’d cross the whole island specifically to visit. Its biggest strength is the combination of a good beach and convenience.

Klong Nin Beach – Best for a Quieter Beach Day

Klong Nin is a good choice if you want a quieter beach without heading all the way to the remote south of Koh Lanta.

It has a more relaxed feel than Long Beach or Klong Dao, but you’ll still find restaurants, beach bars and places to stay nearby.

The beach is long enough that it rarely feels cramped, and I particularly liked the balance here.

You can spend a few hours swimming and relaxing, stay for sunset, then easily find somewhere nearby for dinner or a drink.

Its central location is another advantage. If you’re exploring Koh Lanta by scooter or car, Klong Nin is an easy beach to include while travelling between the north and the quieter southern part of the island.

My tip: Stay until sunset. Klong Nin is a nice place to turn a beach afternoon into an evening, as you can watch the sunset and then walk straight to one of the nearby restaurants or beach bars.

Kantiang Bay – Best for Scenery

Kantiang Bay was one of the beaches that stood out to me for its setting.

Located farther south, the bay is surrounded by green hills and feels much more tucked away than the busier beaches in northern Koh Lanta.

It’s a good place to combine swimming and beach time with the drive south. There are still restaurants, bars and accommodation nearby, so it feels peaceful without being completely isolated.

I especially like Kantiang as part of a day exploring southern Koh Lanta.

You can stop here for a few hours before continuing towards Klong Chak, Bamboo Beach and Mu Ko Lanta National Park.

My tip: Don’t visit Kantiang as your only stop in the south. Combine it with Klong Chak, Bamboo Beach or the national park and make a day of the journey down the coast.

Klong Khong Beach – Best for Beach Bars and Nightlife

Klong Khong is one of the livelier beaches on Koh Lanta. The beach is lined with casual bars and restaurants, making it a good choice if you want somewhere social without a huge party scene.

I’d come here more for the atmosphere, sunset and evening drinks than for the best swimming on the island.

Parts of the beach can become rocky at low tide, so conditions aren’t as consistently good for swimming as at Long Beach or Klong Dao.

Once the sun goes down, the beach bars make Klong Khong one of the better areas for a night out on Koh Lanta.

The atmosphere is generally relaxed rather than full-on, which fits the island well.

My tip: Visit later in the afternoon. You can enjoy the beach, stay for sunset and then have dinner or a drink without needing to go anywhere else.

Nui Beach – Best Small, Secluded Beach

Nui Beach is very different from Koh Lanta’s long, developed beaches. It’s a small bay surrounded by greenery and rocky cliffs, with much less around it than you’ll find at Long Beach or Klong Nin.

The mix of sand, rocks and surrounding nature gives it a more secluded feel. When conditions are good, you can swim here, and there are rocky areas where you may see some marine life while snorkelling.

Just keep in mind that the beach and water can look quite different depending on the tide and sea conditions.

Nui Beach is easy to add to a day exploring southern Koh Lanta, especially if you’re already travelling between Klong Nin and Kantiang Bay.

My tip: Treat Nui Beach as a scenic stop rather than planning your whole beach day around it. Combine it with Kantiang Bay and other beaches farther south.

Klong Chak Beach – Best for a Quiet Southern Stop

Klong Chak Beach is a small, quiet beach in the south of Koh Lanta. It feels much less developed than the beaches farther north, with just a handful of places around the bay.

I wouldn’t necessarily travel all the way south just for this beach, but it’s a lovely stop if you’re already exploring this part of the island.

Spend some time swimming or relaxing here, then continue towards Bamboo Beach and Mu Ko Lanta National Park.

There isn’t much natural shade on the beach, so keep that in mind if you’re visiting around the middle of the day.

My tip: Klong Chak is one of those beaches that makes more sense as part of the journey south. Stop when you get there, see how you like it, and stay longer if the conditions are good.

Bamboo Beach – Best for Scenery and a Remote Feel

Bamboo Beach, also known as Had Mai Phai, is one of the southernmost beaches on Koh Lanta, just before Mu Ko Lanta National Park.

It takes longer to reach than most beaches on the island, but the drive south is part of the experience.

The beach is long, surrounded by greenery and much less developed than Long Beach or Klong Nin.

This is somewhere I’d come for the scenery and peaceful setting, rather than expecting the best swimming on Koh Lanta. There can be rocks underwater, so check the conditions before getting in.

You may also see animals around this part of the island, including monkeys. Enjoy any wildlife from a distance and don’t feed or approach it.

My tip: Combine Bamboo Beach with Kantiang Bay, Klong Chak and Mu Ko Lanta National Park. Together, they make the long drive south much more worthwhile.

Laem Kho Kwang and Hin Ngam – Quiet Beaches in Northern Koh Lanta

Laem Kho Kwang and Hin Ngam are in the north of Koh Lanta, not far from Saladan Pier.

They are much quieter than nearby Klong Dao and can be a nice place for a walk, sunset or simply getting away from the busier beach areas.

This part of the coast feels less developed, with open stretches of beach and greenery around it.

I wouldn’t choose these beaches for the best swimming or spend a whole day here, but they’re worth stopping at if you’re already exploring northern Koh Lanta.

There are fewer restaurants and beach bars than around Klong Dao or Long Beach, although you’ll find some accommodation in the wider area.

My tip: If you only have a few days in Koh Lanta, prioritise Long Beach or Klong Dao instead. Laem Kho Kwang and Hin Ngam make more sense when you have extra time and want to explore beyond the island’s main beaches.

Koh Lanta’s East Coast and Pirate Bay

Most of Koh Lanta’s best-known beaches are on the west coast, but the east coast is still worth exploring.

It feels very different, with mangroves, fishing communities and a wilder shoreline instead of long sandy beaches.

One of the more unusual stops is Pirate Bay, a small beach you can reach on foot

There is some sand here, mixed with a more natural and rugged shoreline, but I’d visit for the setting rather than expecting a classic swimming beach.

For me, the east coast is really about exploring rather than beach-hopping.

The drive itself is part of the experience, with quiet roads, coastal views and small local communities along the way.

My tip: Combine Pirate Bay with Koh Lanta Old Town and other stops along the east coast. My Koh Lanta road trip guide has more ideas for exploring this side of the island.

What Are Koh Lanta Beaches Like for Swimming?

Most of Koh Lanta’s main beaches are along the west coast, and this is where I’d go if swimming and relaxing on the beach are your priorities.

But the beaches aren’t all the same. Long Beach and Klong Dao are among my favourite choices for swimming, while beaches such as Klong Khong can become much rockier at low tide.

Farther south, swimming conditions also depend on the beach, tide and weather.

This is something I noticed while exploring the island: a beach that looks perfect in the morning can feel quite different a few hours later as the tide changes.

If swimming is important to you, don’t judge a beach only by how it looks when you first arrive.

Sea conditions also change throughout the year. During rough weather, even a beach that is normally good for swimming may not be safe.

Always pay attention to the conditions and any local warnings.

My tip: If you’re beach-hopping by scooter or car, stay flexible. If the tide or sea isn’t great at one beach, continue along the coast and try another rather than planning your entire day around one spot.

Where to Stay for the Best Beaches in Koh Lanta

Where you stay matters more in Koh Lanta than you might expect. The island is large and not particularly walkable, so choosing the right beach can save you a lot of travelling every day.

For most first-time visitors, I’d choose Long Beach. You get a good swimming beach, sunsets, restaurants and plenty of accommodation, while still being in a convenient position for exploring the rest of the island.

Klong Dao is another practical choice, particularly for families and shorter stays. If you’d rather be somewhere quieter, look at Klong Nin farther south.

For beautiful scenery and a more secluded atmosphere, Kantiang Bay is one of my favourite options, but you’ll be farther from Saladan and the busier northern part of the island.

If nightlife and beach bars matter more to you, Klong Khong is a better fit, although I wouldn’t choose it purely for swimming.

How to Explore Koh Lanta’s Beaches

Koh Lanta is much larger than islands such as Koh Phi Phi, and you can’t realistically walk between most beaches.

If you’re a confident and properly licensed rider, a scooter gives you the most freedom to stop at different beaches along the coast.

Otherwise, you can rent a car or arrange taxis, tuk-tuk or a private driver.

If you don’t have your own transport, I’d stay around Long Beach or Klong Dao, where you have a beach, restaurants and everyday services close by.

Exploring the quieter beaches in the south will require more planning.

Beaches on Islands Near Koh Lanta

If you have extra time, you can also leave Koh Lanta for a day and explore some of the smaller islands nearby.

I wouldn’t prioritise these over Koh Lanta’s own beaches on a short trip, but they can be a great addition if you’re staying for several days.

Koh Rok – Best for Beaches and Snorkelling

If you want to combine beautiful beaches with a full day of snorkelling, Koh Rok would be my first choice.

The two small islands are part of Mu Ko Lanta National Park and are usually visited on an organised boat trip from Koh Lanta.

Most tours combine several snorkelling stops with time on the beach, so you get both underwater exploring and time to relax.

Koh Rok also makes more sense than travelling to another island simply for another beach.

Snorkelling is a big part of the experience and makes the day feel very different from beach-hopping around Koh Lanta itself.

My tip: Many snorkelling tours combine Koh Rok and Koh Haa, so check the actual itinerary, national park fees and what is included before booking.

Koh Bubu – Best for a Quiet Island Escape

Koh Bubu is a much smaller and less-developed island that you can reach by long-tail boat from Koh Lanta.

The appeal here is the quiet setting rather than a long list of things to do.

You can spend some time on the beach, swim when conditions are suitable and enjoy being somewhere much less developed than Koh Lanta’s main west coast.

Facilities are very limited, so check what you need to bring when arranging your boat.

If you’re comparing islands, here’s how they stack up against the best beaches in Koh Lipe.

Koh Por – Best for a More Local Island Experience

Koh Por is another small island off Koh Lanta’s east coast, but unlike Koh Bubu, it is inhabited.

You can find sandy stretches of coastline here, but I wouldn’t visit purely in search of the “best beach.”

The main reason to include Koh Por is to experience a quieter, more local island and see a different side of the area.

If you’re arranging a private long-tail boat, you may be able to combine Koh Por with Koh Bubu rather than treating them as two separate trips.

Which Nearby Island Should You Choose?

For most first-time visitors, I’d choose Koh Rok. It gives you the strongest combination of beaches and snorkelling and feels different enough from a normal day exploring Koh Lanta.

Choose Koh Bubu if you prefer a quieter and simpler island escape, or consider Koh Por if experiencing a more local island interests you more than having another full snorkelling day.

If you’re looking for kayaking, caves and limestone scenery instead, Koh Talabeng is a better choice—but I wouldn’t choose it specifically for its beaches.

For clearer water and more remote beaches, you can also take a day trip from Koh Lanta.

I cover Koh Talabeng, Koh Rok, Koh Haa and the other main day trips in my Best Things to Do in Koh Lanta guide.
