Koh Lanta for Two
Quiet Andaman Sunset Beaches, Kantiang/Klong Nin Resorts & Old Town Seafood

This is Koh Lanta's most classic honeymoon. Kantiang Bay, in the far south, is a curved sandy beach ringed by green hills, the quietest and most private on the island. It has beachfront resorts like Pimalai Resort & Spa, set across a hillside above the beach, with rooms and villas that have their own pool and a sea view. Klong Nin Beach, in the middle of the island, has adults-focused resorts like Layana Resort that lean into calm for couples. Wake up to a quiet beach and the Andaman Sea right there, a swim for two with no one to share it with — a setting you will not find on a busier island, and ideal for a honeymoon or a special celebration.

For the loveliest sunset over the sea on the island, head to Klong Nin Beach in the middle of Koh Lanta — a long, west-facing beach that is still quiet and wide. In the evening, several beach bars put chairs and cushions right out on the sand, light candles and lanterns, and you can sit with a cold drink, listen to the waves, and watch the sun slowly drop into the Andaman Sea. Standing or sitting hand in hand for the last light of the day on this beach is the romantic spot Koh Lanta regulars love. There is no entry fee and no crowd to fight — just order a drink and let the evening be yours. Many couples carry straight on into a feet-in-the-sand dinner at the same spot.

The far south of Koh Lanta has small, quiet beaches that couples fall for. Kantiang Bay is a curved sandy beach ringed by green hills on two sides, with clear water, a calm feel, and only a handful of restaurants and resorts — a place to sit all day and go nowhere. Nui Bay is a small hidden cove tucked between the headlands, reached through a resort or down a small path, with clear water that is lovely for a quiet swim for two. Both sit where the southern road climbs and winds over the hills, so they stay quiet and feel very private. They are ideal for couples who want to escape the bustle and just be with the sea and each other. Ride a scooter down carefully, as the road is steep, or take a songthaew.

The sweetest date-night dinner on Koh Lanta is seafood in an old wooden stilt house over the water in Lanta Old Town, on the east side of the island — a single seaside lane lined with the old timber houses of the Chinese and sea-gypsy community, many of them now seafood restaurants built out over the sea. Sit over fresh prawns, shellfish, crab and fish under lantern light, with the sound of the water under the floorboards. Pick the catch and have it grilled or stir-fried, and do not miss the southern dishes like grilled prawns, grilled squid and a punchy southern curry, then finish with a chilled fresh coconut. After dinner, stroll the quiet old lane along the sea, which has real character. It is a slow, warm evening you only get on Koh Lanta.

For a moment more special than a beach chair, hire a longtail boat out to watch the sunset from the water for two. A local boatman takes you out to drift just off the shore in the evening, watching the sun drop into the Andaman Sea with nothing in the way — a quiet, very private spot. The other half of a honeymoon many couples love most is the couples spa. Many beachfront resorts have a spa looking onto the sea or tucked into a green garden, where you lie side by side for a massage with the waves in the background, and some have an outdoor massage cabana by the beach for the sea breeze. Book the couples treatment ahead, as evening slots fill fast, and choose a couples package, which often comes with a soak or herbal tea afterwards — a soft way to close the day for two.

For your clearest-water day, take a Four Islands day trip. A boat takes you out to snorkel at Koh Kai, Koh Mor and Koh Tup, where the water is clear over the coral and the fish. The highlight is the white sandbar that surfaces to link Koh Tup and Koh Mor at low tide, so you can walk across the sea for two — and it photographs beautifully. The trip finishes at the Emerald Cave (Tham Morakot) on Koh Mook, where you swim through a dark cave tunnel to reach a hidden emerald-green lagoon in the middle of the island, a thrill you do together. The trip runs as both longtail and speedboat from Koh Lanta. It is the best day for swimming and couples photos on the trip — take a morning departure to skip the crowds and get the clearest water.

If you are a couple who loves a clear sea, add a trip to Koh Rok and Koh Haa, south of Koh Lanta. Both have the clearest water and best coral in the Lanta area. Koh Rok has fine white-sand beaches and turquoise water, great for snorkelling over the coral and colourful fish, while Koh Haa is a cluster of five limestone islands with clear lagoons and small caves that divers love. The trip is usually a full-day speedboat from Koh Lanta. It is ideal for couples who want a postcard sea and do not mind a longer boat ride. One important thing to know: Koh Rok and Koh Haa are inside a national park that usually closes in the monsoon (around May to October) because of rough seas, so they can only be visited in the dry season — check that they are open before you plan.

The key thing couples often miss — Koh Lanta's beaches run in a line down the west coast, so it is better to pick one and settle into it than to keep moving. For couples there are three broad choices. Klong Dao and Long Beach (Phra Ae) in the north are closest to Saladan Pier and the restaurants, with a good swimming beach — handy, and ideal for a first visit. Klong Nin Beach in the middle is long and quiet, with lovely sunsets and beach bars to walk to — ideal if you want quiet but still want somewhere to go. And Kantiang Bay and Nui Bay in the far south are the quietest and most private, ringed by hills, but far from the pier and the town's restaurants. Pick the one that fits the trip you want.

Not every romantic moment has to cost something — an evening walk on the beach at golden hour is the most free-of-charge romance on Koh Lanta. The lovely thing about this island is that the whole west coast faces the sunset, so wherever you stay you can walk out from your resort and watch the sun slip into the Andaman Sea. Walk hand in hand by the water, listen to the waves, and watch the sky turn orange and pink. Klong Nin and Long Beach are long enough for a proper walk, while Kantiang Bay is so quiet it feels like a private beach. Many couples love a stroll along the sand after dinner, listening to the waves under the stars — a quiet stretch of being together with nothing to plan.

Timing matters a lot for a beach trip for two. November to April is the dry season and Koh Lanta's best window — bright skies, clear water and little rain, ideal for beach walks, a boat out to the islands and sunsets, with the resorts and ferries all running fully. May to October is the Andaman monsoon, with frequent rain and rough seas at times, when some resorts and restaurants close and some ferries cut back or stop; the offshore island trips like Koh Rok and Koh Haa usually close because they are inside a national park. The upside of the monsoon is that it is quiet and much cheaper — if you come then, choose a resort that stays open and check the ferry schedule first. Late April brings Songkran, which is lively on the island. For clear skies, a lovely sea and everything running, the dry season is the best value.
