Koh Libong sits in Koh Libong subdistrict, Kantang district, Trang province, and it's the largest island in the Trang sea, covering roughly 25,000 rai (about 40 sq km) of mountains, flatland, mangrove forest, and beaches. Most islanders are Muslim fishing families who've lived here for generations, making a living from fishing and guiding visitors. What matters most is what's around the island: the widest seagrass beds in the country, which makes it a feeding ground and home for the dugong herd. The whole island has been declared a non-hunting area to protect the dugongs and migratory birds.
Libong's charm is its unpolished, natural feel. It hasn't been overrun the way Koh Kradan or Koh Mook have. If you love quiet, watching wildlife, and seeing how a community really lives, you'll love it here. But if you're coming for pretty cafes or postcard-clear water, Libong might not be your thing — we'll be straight with you up front.
Dugongs and seagrass: why come to Libong to see them
The dugong (called duyong in the local dialect) is a marine mammal that lives mainly on seagrass. Libong is home to a real herd numbering in the hundreds — the largest in Thai waters. The reason is the seagrass meadows around the island, which are remarkably rich, especially off Juhoy Cape and Tochai Cape. At low tide the seagrass surfaces into a wide green flat stretching as far as you can see.
There are two ways to watch dugongs here: sit and wait at the dugong-watching tower out on the pier walkway, or charter a local boat and cruise the spots where dugongs like to come up and feed. The honest truth is that dugongs are wild animals — nobody can guarantee you'll see one on the day you go. Some people catch a whole group surfacing for air; others sit all morning and see nothing. It comes down to the tide, the wind, and luck. If you're coming purely for the dugongs, leave a little room in your heart for disappointment.
The golden hours for dugong watching
Dugongs usually come up to feed on the rising tide, and they're easiest to spot from morning to midday when the water is calm and the wind is still. Check the tide table for your travel day with your homestay in advance, and have them schedule the boat to match the good tide window — it raises your chances a lot.

Spots on Koh Libong you shouldn't miss
Dugong-Watching Tower (Marine Life Observation Tower)
A wooden walkway runs about 1 km out into the sea, ending in a tall multi-level tower. Climb up to sit and wait for dugongs while taking in the full view of the island around you. This is the main spot everyone who comes to Libong has to do. Go in the morning on a rising tide for the best chance of spotting a dugong.
Juhoy Cape
The cape on the eastern tip of the island, a sunrise spot and a huge seagrass bed. At low tide you can walk out onto the seagrass flat and find fiddler crabs, shells, and small creatures from the seagrass ecosystem everywhere you look.
Thung Ya Kha Beach
A quiet beach on the far side of the hill, with a long stretch of white sand and few people — perfect for sitting back and catching the breeze without anyone bothering you. It's one of the spots migratory birds like to land in the cool season.
Batu Pute Hill (Hilltop Dugong Viewpoint)
Another dugong-watching spot besides the tower, with a fairly easy stairway up. Climb to the top and look down on the seagrass meadows and dugongs from above — a much wider view than the tower gives you.
Tochai Cape
A beach and rocky cape on the other side of the island, with clearer water than the seagrass side — good for a swim and photos. Island-tour boats often stop here on their loop around the island.
Mangroves and Channels Around the Island
Paddle a kayak or take a small boat through the mangroves to see the mangrove ecosystem, egrets, and the crab-eating macaques that come out along the channel banks. It's a relaxed late-morning or afternoon activity.
Night Squid Fishing
Head out with the locals in the evening to jig for squid in the bay. Whatever you catch, you bring back for the homestay to cook up fresh. It's a popular activity that's fun and gets you the freshest seafood imaginable.
The Fishing Village and Morning Market
Wander through the Muslim fishing village to see real daily life — longtail boats lined up along the shore, and a morning market selling fresh fish just back from the sea. It's a chance to talk with locals and understand the island better.
A note on island etiquette
Libong is a Muslim community, so dress modestly when walking through the village — don't stroll past people's homes in a bikini. Alcohol is hard to find on the island and most places don't sell it, so if you want a drink you'll need to bring your own, and you should drink it at your own accommodation.
How to get to Koh Libong
There's only one way to Libong: catch a boat at Hat Yao Pier in Kantang district. From Trang town it's about a 40-50 minute drive or ride to Hat Yao Pier. If you come by train, get off at Kantang station and take a connecting ride to the pier. From Hat Yao Pier, the longtail boat crossing to the island takes only about 15 minutes.
- Shared longtail boat — around 40-50 THB per person, running throughout the day from roughly 07:00-17:30; departs once there are enough passengers
- Boat charter — if you don't want to wait, or you're a group, charter a whole boat for around 400-500 THB and go straight over with no waiting
- Getting to the pier from Trang town — rent a car and drive yourself, or charter a van/songthaew to drop you at Hat Yao Pier; allow time to catch a boat departure
- On the island — get around by the locals' motorbike taxis, or have your homestay arrange a vehicle to take you sightseeing; there's no city-style public transport
Check before you set off
Longtail boats depend on the weather and the swell. During monsoon season (roughly May-October) the swell can be strong and boats may not run on some days, so call your accommodation to check before you travel. And if you're coming seriously to watch dugongs, the dry season (November-April) has calmer seas and easier sightings.
Where to stay on Koh Libong
Accommodation on Libong is mainly local homestays and small resorts, most of them right on the water, serving fresh seafood and often including boat tours. Prices are low and the atmosphere is friendly. Don't expect a luxury hotel — think of it as staying at the home of a sea-gypsy friend, and you'll be happier for it.
Rabieng Lay Koh Libong Homestay
A beachfront homestay with a warm, homey atmosphere, serving fresh seafood and barbecue, plus boat tours and squid-fishing trips. Great for anyone who wants the full sea-gypsy experience.
Baan Khon Hua Laem Koh Libong
Sea in front, mountain behind — two kinds of view in one place. Quiet and peaceful, ideal for genuine rest and relaxation.

A beachfront resort with more amenities than the typical homestay. Good for anyone who wants a bit more comfort while still being right on the water.

When to go and how to prepare
The best time is the dry season, November to April: the sea is calm, boats run easily, dugongs are easier to see, and it's exactly when the migratory birds arrive. The monsoon season, May to October, brings strong swells and heavy rain, and boats are cancelled on some days. If you do come during this period, you'll need to check the weather and stay flexible with your plans.
- Book accommodation ahead — there aren't many places on the island, and they fill up fast in high season
- Bring cash — ATMs are hard to find on the island, and most shops take cash only
- Sunscreen and water shoes — you'll be walking on seagrass and rock at low tide, so wear shoes that can get wet
- A zoom camera or binoculars — dugongs and birds are far off, so these help a lot
- Keep an open mind about dugongs — they're wild animals, and whether you see one comes down to the day; come mainly for the atmosphere and the nature and you won't be disappointed
Watching dugongs without disturbing them
When a boat gets near a dugong, the driver should slow the engine and keep a distance — don't chase, herd, or crowd them. Dugongs spook easily and can be injured by boat propellers. Choose a local boat guide who knows the rules of conservation-minded viewing; it helps keep the dugongs around for the long run.
Combining Libong with other islands in the Trang sea
Libong is part of the Trang island group, which is easy to island-hop. Many people build an island-hopping trip pairing Libong with nearby islands. If you have several days, try slotting Libong in as your quiet nature day, then follow it with an island that has clearer water for swimming and snorkeling.
Koh Kradan
The white-sand, clear-water island that Trang visitors love most. A great follow-on from Libong for swimming and snorkeling.
SnorkelingKoh Cheuk
A snorkeling spot for coral and fish in the Trang sea, usually included on island-hopping trips.
Sea CaveEmerald Cave, Koh Mook
Swim through a dark cave to a hidden beach in the middle of the island — the highlight of the Trang sea.
