Koh Libong is Thailand's dugong capital — the country's largest dugong population in protected seagrass beds, year-round island access, mangrove forests, and a genuine wildlife experience without the tourist crowds. Our guide covers the top resorts and how to maximise your chances of a dugong encounter.
Koh Libong: Thailand's Dugong Island
Koh Libong is a large island (45 km²) in Trang Province — Thailand's most important dugong habitat and one of the country's least-visited islands. The island has a small Muslim fishing community, rubber plantations, mangrove forests, and the Libong Archipelago Wildlife Reserve, which protects the seagrass beds that support Thailand's largest dugong population.
Unlike the national park islands (Koh Ngai, Koh Kradan, Koh Lipe) which close in monsoon season, Koh Libong is accessible year-round. The accommodation is simple — Libong Beach Resort is the most comfortable option — but the dugong encounters and genuine quiet make it exceptional for wildlife-focused travelers.

Dugong Encounters
Koh Libong has Thailand's largest dugong population — approximately 200 individuals in the surrounding seagrass beds. Dugong boat tours (arranged by the resort) navigate the seagrass areas in the early morning, when dugongs surface to breathe. Sightings are not guaranteed but are frequent — Koh Libong is one of the most reliable dugong destinations in Southeast Asia.
Dugongs are gentle, slow-moving animals — encounters are calm and non-intrusive. Swimming with dugongs is not permitted (they are protected), but boat-based observation is excellent.
Libong Archipelago Wildlife Reserve
The reserve protects the seagrass beds, mangrove forests, and coastal habitats around Koh Libong. Beyond dugongs, the reserve supports:
- Sea turtles: Green and hawksbill turtles in the surrounding waters
- Irrawaddy dolphins: Occasionally seen in the channels between islands
- Shorebirds: The mangroves are important habitat for migratory shorebirds
Getting to Koh Libong
- From Kantang pier: 20-minute longtail boat. Kantang is 20km from Trang town.
- Year-round access: Unlike other Trang islands, Koh Libong has ferry service year-round.
Best Time to Visit
- November–April: Dry season, best beach conditions, calmest seas.
- May–October: Accessible year-round (unlike national park islands), but rougher seas.
- Dugong sightings: Year-round, most reliable November–April.
Frequently Asked Questions
Is Koh Libong good for snorkeling?
Moderate — the reefs around Koh Libong are not as spectacular as the national park islands. The main draw is the dugong encounters and wildlife rather than snorkeling. For snorkeling, combine with a day trip to Koh Ngai or Koh Kradan.
Is Koh Libong open year-round?
Yes — unlike the national park islands (Koh Ngai, Koh Kradan, Koh Lipe) which close May–October, Koh Libong is accessible year-round. This makes it a viable option when other Trang islands are closed.
