10 Best Beaches in Koh Lanta (2026 Guide + Insider Tips)
The beaches of Koh Lanta are truly unique, making this beautiful island in Thailand an ideal vacation paradise for beach lovers and those seeking peace and quiet. We’ve already visited three times and explored countless swimming spots. What surprised us most: despite being a relatively laid-back island, Koh Lanta offers a wide variety of truly stunning beaches that are perfect for swimming, snorkeling, and relaxing. The long bays in the north are ideal for extended beach walks, while the spectacular beaches in the south are real eye-catchers and still relatively untouched. It’s no surprise that backpackers and independent travelers love this charming island. The laid-back hippie vibe and the picturesque beaches are exactly why we keep coming back.
In this travel guide, we’ll show you the most beautiful beaches on Koh Lanta, starting from the north of the island all the way down to the south. This article is based on our weeks-long stays on Koh Lanta and our personal experiences exploring its beaches. We’ll also share stunning photos, real hidden gems, the best swimming spots, and tips for great places to stay in Koh Lanta.
Long Beach (Phra Ae Beach)
Long Beach, also known as Phra Ae Beach, is the most famous and, at 5 kilometers, the longest beach on Koh Lanta. Especially if it’s your first time on the island, this beach is a great choice. We’ve stayed here several times, as it offers a wide range of accommodation, from simple budget bungalows to quality hotels. There are also plenty of beach bars and restaurants lining the coast.
In our experience, this beach is excellent for swimming at both low and high tide. Even though Long Beach is very popular, it never feels crowded, probably thanks to its size, even during high season. Another great bonus is the pine trees along the shore, which provide pleasant shade on hot days.
Tip: Sun Long Beach Resort offers beautiful bungalows in a great location right by Long Beach. The balcony hammocks are perfect for relaxing, and the beach is just a short walk away.
Relax Beach
Relax Beach, often also called Relax Bay, is definitely one of the best beaches on Koh Lanta and still a real hidden gem for a peaceful and beautiful stay. We spent three days here but would definitely stay longer next time. The rustic beach bars create a true hippie vibe, and it’s the perfect place to unwind and enjoy the stunning surroundings with a cold drink. The small bay feels somewhat secluded from the rest of the island, creating a very special atmosphere. During the day, it’s usually very quiet, making it an ideal spot for relaxing.
Tip: There are a few really nice bungalows right on the beach. An insider tip is the Lanta Casa Blanca, a wonderful beach hotel with a beautiful pool and a fantastic location by the sea.
Klong Khong Beach
Klong Khong Beach is a beautiful 3-kilometer stretch of especially soft sand located in the middle of Koh Lanta’s coastline. Its central location makes it a great base for exploring the island and visiting its main attractions. However, one thing we noticed: at low tide, the beach can be quite rocky, which makes swimming a bit more difficult—water shoes are definitely helpful here. At high tide, though, this section becomes much more enjoyable, with the water reaching almost up to the charming little beachfront bars. This beach is also popular with backpackers, as there are still several affordable accommodation options available.
Tip: A real insider tip is The Lazy Lodge, a beautifully designed resort in a great location directly on the beach, with stylish bungalows and excellent breakfast.
Kantiang Bay
Kantiang Beach is an absolute holiday dream on Koh Lanta and, to be honest, one of our personal favorites. The setting is incredibly beautiful, and it’s no coincidence that this gem is regularly listed among the best beaches in Thailand. The white sandy beach stretches for about 2 kilometers, and the color of the sea has impressed us every single time we’ve visited. What we especially love is that you won’t find large crowds here, meaning you can often enjoy this beach almost entirely to yourself. Another highlight is the restaurants along the coastal road heading south, where you can enjoy breathtaking views over Kantiang Beach while dining.
Tip: You can also find great accommodations on Kantiang Beach, such as the luxurious and fantastically beautiful Pimalai Resort, one of the best hotels on the island.
Klong Nin Beach
Klong Nin Beach is a long, beautiful sandy beach and certainly one of the most popular beaches on Koh Lanta. We especially loved the atmosphere in the late afternoon, when the colorful beach bars and restaurants start to fill up and people gather to watch the sunset. Thanks to its central location, Klong Nin Beach is also an excellent base for exploring the island’s highlights and other beautiful beaches. You’ll find plenty of accommodation options here, mostly in the more affordable price range, as well as several great restaurants that invite you to linger and enjoy.
Tip: Highly recommended is at the Klong Nin Beach the Andalay Boutique Resort, a beautiful small hotel, with lovely bungalows and top beach location!
Klong Jark Beach
Klong Jark Beach is truly a fantastic beach tip for Koh Lanta and a great choice if you love quiet, peaceful beaches. The overall atmosphere here is very relaxed and cozy, making it especially popular with independent travelers. You can also go snorkeling here, as the turquoise water is wonderfully clear. If you’re planning to stay at this dream beach, you’ll find a few simple accommodations and charming bungalows. Nearby, you can also visit the Klong Jark Waterfall, which can be reached via an exciting jungle hike.
Tip: Directly on the beach is the charming Anda Lanta Resort, with a nice pool and in a wonderful location. Perfect for a quiet beach vacation on the island of Koh Lanta.
Nui Beach
Nui Beach is a small, beautiful bay in the southern part of Koh Lanta, and we experienced real “wow” moments here during our very first visit. The water is crystal clear and shines in the most stunning shades of turquoise. Surrounded by lush green vegetation, this beach feels like something straight out of a travel magazine. Despite its beauty, we were always able to find quiet spots for swimming and relaxing. You’ll get an incredible view from Diamond Cliff Beach Resort, where a path also leads down to the beach. Nui Beach is also a fantastic photo spot and stands out clearly from the long sandy beaches in the north, making it one of the most beautiful beaches on Koh Lanta.
Nui Bay
Nui Bay, not to be confused with Nui Beach mentioned above, is a small bay located further south on Koh Lanta. Here, you’ll find a secluded beach with stunning sea colors and an incredibly peaceful atmosphere. To this day, there are no accommodations here, and only one small hippie-style beach bar provides hammocks and a bit of shade. We instantly fell in love with this little spot and enjoyed the scenery from there. This beach is still considered a hidden gem on Koh Lanta, and its untouched nature makes it one of the island’s highlights.
Bamboo Bay
Bamboo Bay is located at the very southern end of the island and is the last beach before entering the national park. For us, this beach is a true favorite, especially when it comes to nature and tranquility. This bay remains largely untouched, offering a beautiful, natural white sandy beach surrounded by dense jungle. If you’re looking for peace and solitude, you’ll definitely experience unforgettable days here. At this far end of the island, it almost feels remote, and it’s especially loved by those seeking complete relaxation.
Tip: Really charming is the Lalaanta Hideaway, a perfect accommodation to relax at Bamboo Bay. Guests love the secluded location and the wonderful pool.
Ta Naoad Beach (Koh Lanta Lighthouse)
At the southern tip of the island lies the picturesque Ta Naoad Beach, right next to the famous Koh Lanta lighthouse. This stunning beach is part of Mu Ko Lanta National Park, making it very clean and wonderfully unspoiled. The sea shines in breathtaking shades of turquoise, creating a picture-perfect setting together with the lighthouse. If you visit the national park, you should definitely take some time to swim and relax here. With a bit of luck, you might even spot a few monkeys that occasionally visit the beach.
Conclusion
The beaches of Koh Lanta never fail to impress us time and time again. If you’re visiting for the first time, you shouldn’t miss well-known highlights like Long Beach or Kantiang Bay. At the same time, it’s definitely worth venturing off the beaten path and exploring the coastline on your own—especially places like Nui Beach, Nui Bay, and Bamboo Bay, where we discovered some of our most beautiful and peaceful favorite spots.
