Nui Beach is a reward for a small detour rather than a beach you fall onto from the road, and that is exactly its appeal. It sits in the south of Koh Lanta, off Route 4206, and you reach the sand not by a public path but by a set of steep steps beside the beachfront restaurant that guards the access. That little barrier keeps it quiet. Where the west coast beaches run long and developed, Nui is a secluded green cove, wrapped in headland and jungle, the kind of place where you hear the sea and the birds more than other people.
Let me be plain about what it is and is not. The sand here is brown and grainy rather than the pale powder Lanta is famous for, and the water, while clear and warm, has rocks in the shallows and an open aspect that can turn the sea choppy on the wrong tide. So this is not the island's easiest swim. What it is instead is scenery and seclusion, a wild little bay with a restaurant terrace above it that looks straight out over the water, ideal for a long lunch, a cold drink and a slow afternoon watching the light on the sea. Monkeys are regulars, used to people, so keep your food and bags secured and enjoy them from a distance.
Come prepared and it delivers. The steps are steep, so it is not the pick for young children or anyone with limited mobility, and you should bring water, sun cover and reef safe products since services are limited to the one restaurant and its rinse off shower. Time your swim to a calmer, higher tide, tread carefully over the rocks, and swim within your depth as there is no lifeguard. Treat Nui as a scenic, wild escape rather than a swimming resort and it becomes one of the more memorable corners of Lanta.
Come to Nui for the seclusion and the view, then use Lanta's west coast for the easy swimming. For the island's most photographed southern bay go to Kantiang Bay, for a long relaxed sunset beach try Klong Nin Beach, and for a lively main stretch see Long Beach.

Nui is a secluded cove served by a single beachfront restaurant and bar at the top of the access steps, not a built beach club, and we will not invent one. That one venue is where you eat, drink and rinse off, and it is part of what keeps the bay so quiet. For loungers, spa days and the larger developed venues, look to Lanta's west coast and use the Koh Lanta beach clubs directory.

Come for the seclusion, the greenery and the long view over the water, keep your gear light for the steep steps, and treat lunch and a cold drink as the ritual. For loungers and larger venues, browse the Koh Lanta beach clubs directory and the west coast beaches.
Nui Beach is in the south of Koh Lanta, reached by heading down Route 4206 and turning in at the beachfront restaurant that holds the access. You leave the scooter or car at the top, where parking is usually free, and take a set of steep steps beside the restaurant down to the sand, or ask a songthaew driver for Ao Nui. The steps are the main obstacle, so plan for them rather than expecting a level walk on.
Because services are limited to the one restaurant, bring water, sun cover, reef safe products and anything else you want for the day, and carry it back up. Time your swim to a calmer, higher tide, watch your footing on the rocks, keep food and bags secured against the monkeys, and swim within your depth as there is no lifeguard. The dry season is calmest, while the monsoon brings a bigger sea on this open coast. Conditions are typical rather than guaranteed.

By road down the south of Koh Lanta on Route 4206, then in through a beachfront restaurant that owns the access. You reach the sand by a set of steep steps beside the restaurant, with parking usually free at the top, and a songthaew from elsewhere on the island will drop you if you say Ao Nui. The steps are steep, so it is not the easiest access for young children or anyone with limited mobility.
It is scenic but it is not a flawless swimming beach, and we will be honest about that. There are rocks in the water and the cove is fairly open, so the sea can be choppy and the entry uneven on some tides. Pick a calmer, higher tide, watch where you step, and swim within your depth, since there is no lifeguard and conditions are typical rather than guaranteed.
No, and it is worth knowing before you go. The sand at Nui is more brown and grainy than the pale powder of Lanta's west coast beaches, part of its rugged, natural character rather than the postcard look. People come here for the seclusion, the greenery and the scenery, not for a bright white strand, so set your expectations to wild rather than polished.
No built beach club, and we will not invent one. Service comes from the single beachfront restaurant and bar at the top of the access steps, which also offers a rinse off shower, rather than a row of day beds. For loungers, spa days and larger venues, look to the developed west coast beaches and use the Koh Lanta beach clubs directory.
Yes, monkeys are known to visit the beach and are used to people. Enjoy watching them from a distance, but do not feed them and keep food, bags and shiny items secured, as habituated monkeys can be bold. Give them space, especially around young ones, and they will leave you to your day.
