The Must Do Activities in Koh Lanta
(because this island is way more than a hammock and a coconut)
Koh Lanta is one of those places that tricks you at first glance. You arrive thinking you’re about to spend a week horizontal on a beach and suddenly the island is like SURPRISE! There are actually a million cool things to do. But what should you do while you are on Koh lanta? Here’s your guide to the absolute musts so you don’t accidentally miss out and then spend the flight home wondering why no one told you.
🐠 Snorkeling
Koh Lanta sits near some of Thailand’s most beautiful snorkel sites and the water here is basically a giant open aquarium. Hop on a longtail or speedboat and cruise to places like Koh Rok or Koh Haa where the visibility is so good you’ll see fish judging you before you even get in the water. Expect colorful reefs, gentle currents and every shade of blue your eyes can handle. It’s the perfect activity if you want ocean magic without having to strap 20 kilos of gear to your back.
🤿 Diving
If you are the type who enjoys sinking a little deeper into ocean chaos the diving around Koh Lanta is legendary. Hin Daeng and Hin Muang are the showstoppers with steep walls, schools of fish and the possibility of bumping into a manta ray that looks like it’s about to ask for directions. With calm seas in high season, great visibility and a friendly dive community the island is a dream base for both new and experienced divers. Just be warned once you dive here you’ll start looking up flights back way too often.
🚤 Island hopping
Island hopping from Koh Lanta is like flipping through a catalogue of perfect tropical screensavers except you’re actually in them. The Four Islands Tour takes you through caves, lagoons, beaches and clear water that actually sparkles in the sun. Trips to Koh Rok and Koh Haa usually include snorkeling stops and a beach picnic which makes you feel like you’re starring in a mildly chaotic travel commercial. It’s one of the easiest and most satisfying ways to spend a day.
🛶 Kayaking through the mangroves
If you want to escape the beach crowds and flex your inner nature explorer, grab a kayak and head into the mangroves of Tung Yee Peng. This area is peaceful green and honestly a bit dramatic in the best way. You glide through tree tunnels, spot birds and crabs living their best lives and enjoy a side of Koh Lanta that most people forget exists. It’s calm, quiet and perfect for anyone who wants a break from salt water.
🛵 Scooter exploring
There is nothing more freeing on Koh Lanta than renting a scooter and zooming down the long coastal roads feeling like you’ve been cast in a Southeast Asian version of a road trip movie. You can stop anywhere: cute cafes, hidden beaches, cliff viewpoints or just random spots where you suddenly need a coconut. The island is big enough to feel like an adventure but small enough that you won’t get lost forever which is comforting even if your sense of direction is a tragic mess.
🍜 Eating everything in sight
Koh Lanta is one of the easiest places to accidentally fall into a food coma. Beachfront restaurants serve fresh seafood and spicy curries, local noodle shops offer bowls of joy for pocket change and cafes make you wonder whether you should just become a digital nomad and “work” from here forever. Whatever you do, don’t leave without trying massaman curry at least once. Your future self will thank you. If you don’t know where to eat first, we got you!

🌅 Sunset chasing
If the west coast of Koh Lanta had a LinkedIn profile it would brag about its sunsets. The sky turns into layers of pink, orange and purple while everyone quietly transforms into a professional photographer. Grab a drink, find a beanbag and let the sky do its dramatic thing. Even if you’ve been burnt by too many sunset promises in the past this one delivers. If you’re not sure where to catch the best sunset, just check out our Koh Lanta sunset guide for a little inspiration.
🌴 Visiting Lanta Old Town
Lanta Old Town feels like someone forgot to tell it the rest of the island is busy being beachy. Wooden houses sit on stilts above the water, cute restaurants line the street and shops sell artsy little things you absolutely don’t need but will buy anyway because you’re on holiday and logic has left your body. It’s peaceful, charming and a great way to see a side of Lanta that’s not all bikinis and beachfront smoothies.
Pro Tip: Go in the morning or evening, when the sun is not burning down on oue head.
🦝 Exploring Mu Ko Lanta National Park
At the far south of the island you’ll find a national park straight out of an adventure movie. There are jungle trails, lighthouses, wild beaches and enough monkeys to make you deeply reconsider eating snacks outside. It’s a gorgeous spot to stretch your legs, cool down in the sea and feel like a real explorer.
🧘 Serious beach bum duties
Look, this one is important! You should absolutely spend time doing nothing but reclining on a beach chair, sipping something cold and listening to the waves. Consider it essential cultural immersion. Koh Lanta’s beaches are long, quiet and ridiculously relaxing which makes this the ideal island for perfecting your professional lounging technique.
Final thoughts
Koh Lanta is one of those rare places where every day feels easy in the best possible way. Whether you spend your time exploring jungles, drifting through mangroves, eating your way across the island or perfecting the art of doing absolutely nothing. This place has a way of sneaking into your heart. And while the sunsets and beaches are incredible, the real magic is waiting just offshore where the water is clear and full of life. You don’t have to be a pro to enjoy it. Either an island hopping tour, a simple snorkel tour or a relaxed intro dive is often enough to turn your whole trip into a highlight reel. So come for the island vibes, stay for the ocean and let Koh Lanta show you why so many travelers end up returning again and again.
