Koh Libong is the largest island in Trang Province, located in Kantang District. Most of the island is designated as the Libong Archipelago Wildlife Non-Hunting Area, which helps preserve its highly rich and intact ecosystems both on land and in the sea. The island is especially known for its extensive and diverse seagrass beds, which serve as the main food source for dugongs, as well as an important nursery ground for juvenile marine life and a key system for maintaining coastal balance.These seagrass habitats make Koh Libong the last stronghold of dugongs in Thailand, with an estimated population of around 100–200 individuals. Dugongs usually feed in shallow seagrass areas and move slowly and cautiously, making sightings possible only under suitable water conditions.

Beyond its marine ecosystem, Koh Libong features diverse geography. The eastern side is dominated by seagrass areas and dugong viewing points, while the western side offers sandy beaches and beautiful sunset spots. The inner island is home to local communities and rubber plantations.Life on Koh Libong is simple and rooted in a Muslim fishing community. Most residents work in small-scale fishing and rubber tapping, while homestays and community-based tourism are gradually increasing. Visitors can experience a peaceful and friendly local lifestyle.Tourism on the island focuses on slow, nature-based travel. Visitors often use sidecar motorcycles (saleng) or rented motorbikes to explore attractions such as the natural stone bridge, Lang Kao Beach, the dugong observation tower, and freshwater ponds that appear during low tide.

The best time to visit is from November to April, when the weather is pleasant and the sea is calm. During the monsoon season, travel and boat access may be limited in some areas.Koh Libong is therefore an important area for marine biodiversity, dugong conservation, and local cultural heritage, remaining one of Thailand’s most natural and unspoiled island destinations.
