Laem Son National Park, National park and wetland reserve on the Andaman Sea coast, Thailand
Laem Son National Park is a coastal protected area on the Andaman Sea featuring mangrove forests, coral reefs, and white sand beaches spread across a long line of bays. The terrain includes several islands and inlets where salt marshes transition into shallow waters, and the landscape constantly shifts between land and sea.
The area was officially designated as a national park in 1983 to protect its delicate coastal ecosystems and marine environments. This decision marked a turning point in recognizing the importance of these waters and habitats for long-term preservation.
Fishing traditions shape daily life in nearby villages, and you can see traditional boats anchored in the bays. Local families continue these practices alongside tourism, making their routines visible to visitors who explore the waterfront areas.
The best time to visit is between November and April when the weather is dry and conditions are favorable for activities. Reach the park from Ranong, and plan time for boat trips between the islands and bays since these are the main way to explore different locations.
Macaques on the islands of Piak Nam Yai and Thao show remarkable intelligence by using stones to crack open shellfish. This behavior is rare in wildlife and makes the islands a special spot to watch this visible difference among the primates.
