The NP is a coastal area with beaches , coral reefs , mangrove swamps , and a rainforest jungle . From the beach at Hat Bang Ben , some of the 20 offshore islands are visible , such as Ko Kam Yai , Ko Kam Noi , Mu Ko Yipun , Ko Khang Khao , and Ko Phayam , while Ko Kam Tok ( alternate Ko Ao Khao Khwai ) and Ko Kam Yai are not visible from this beach . The islands of Piak Nam Yai and Thao are noted for stone-tool usage by long-tailed macaques . In 2002 , the Laemson National Park-Kapoe Estuary-Kra Buri River Estuary area became a designated Ramsar site . Subsequent to the 2004 Indian Ocean earthquake and tsunami , the park headquarters were flattened , and Ao Khao Khwai ( Bull Horn Bay ) was split into two small islands . A consortium of institutional partners are facilitating a mangrove restoration project at Laem Son
