Khao Laem Ya-Muko Samet National Park, Rayong

Khao Laem Ya-Muko Samet National Park protects both coastal headlands and the pristine islands of Ko Samet archipelago, creating Thailand’s unique marine-terrestrial national park experience. Rocky cliffs plunge into turquoise waters while tropical forests blanket the mainland hills, offering visitors a rare combination of hiking trails and island exploration just two hours from Bangkok. The park’s dual nature means you can trek through dense woodland in the morning and snorkel among coral reefs in the afternoon.

Mainland trails wind through dipterocarp forests where hornbills call overhead and monitor lizards rustle through undergrowth thick with the scent of flowering trees. The Khao Laem Ya headland trail rewards hikers with panoramic views across the Gulf of Thailand, while the shorter nature walks reveal pitcher plants and rare orchids clinging to limestone outcrops. Ko Samet’s white sand beaches provide excellent snorkeling opportunities, particularly around the northern and eastern shores where colorful reef fish dart between staghorn corals. Several smaller islands in the archipelago remain largely untouched, accessible only by longtail boat for those seeking complete solitude.

Peace defines the park experience, broken only by waves lapping against rocky shores and the distant calls of sea eagles circling offshore islands. Early morning mist clings to forested hills while fishing boats dot the horizon, creating an almost meditative quality that contrasts sharply with Thailand’s busier tourist destinations. The combination of forest sounds and ocean rhythms creates a natural soundtrack that slows your pace and clears your mind.

Visit during the cool season (November to February) for the most comfortable hiking conditions and clearest waters for snorkeling. Regular buses connect Bangkok to Rayong town, followed by songthaews to the park entrance. Entry fees are 200 baht for foreign adults and 100 baht for children, significantly higher than the Thai national rates. Bring hiking shoes, swimwear, and plenty of water – camping is available with advance booking for those wanting to experience the park’s nocturnal wildlife activity.
