Ream National Park is a coastal protected area in Kampot province on the Gulf of Thailand in southern Cambodia, covering mangroves, islands, beaches and lowland forest. The park conserves both marine and terrestrial habitats and supports a range of coastal biodiversity.

Key features include extensive mangrove stands, offshore islets and sandy beaches, and interior lowland rainforest with freshwater streams. Visitors use boat trips to reach islands and coastal viewpoints and can encounter shorebirds, marine life and forested trails depending on season and tide.

The park was established as a protected area to conserve coastal ecosystems and is managed within Kampot province; it lies near the urban centers of Sihanoukville and Kampot and is reachable by road and by boat from coastal communities.

The landscape is principally flat coastal terrain with tidal channels, intertidal zones and small offshore islands forming the park’s marine boundary.

  • Area: The park covers a coastal area of roughly 21,000 hectares and combines mangroves, beaches, islands and evergreen forest in Kampot province on Cambodia's Gulf coast.
  • Access: Access is primarily by road to park entrances and by boat for island and coastal visits, with local operators offering guided tours and boat trips from nearby Sihanoukville and Kampot.

What to See #

  • Mangrove zone: Coastal mangrove forests that fringe the shorelines and provide habitat for juvenile fish, crustaceans and shorebirds within tidal channels.
  • Islands and beaches: Offshore islands and sandy beaches that are part of the park and offer coral and shallow-water marine habitats accessible by boat.
  • Rainforest interior: Interior lowland evergreen forest and secondary woodland that support terrestrial wildlife and connect to freshwater streams entering the coastal zone.

How to Get to Ream National Park #

Ream National Park sits just outside Sihanoukville (Kampong Som). From Sihanoukville town drive or take a taxi/tuk‑tuk on the local coastal roads toward Prey Nop; the park is roughly 15-20 km from Sihanoukville town (about a 20-40 minute drive depending on traffic).

If coming from Phnom Penh, take National Road 4 to Sihanoukville (by long‑distance bus or car) and then continue by local road/taxi to the park entrance.

Tips for Visiting Ream National Park #

  • Access the park from Sihanoukville - many boat tours and licensed guides depart there for Ream's mangroves and nearby islands, so book a boat through a reputable operator rather than attempting to navigate the tidal channels alone.
  • Plan wildlife-spotting for early morning when birds and estuarine wildlife are most active and boat traffic is lighter, and ask your guide to take the narrower mangrove channels where shorebirds and kingfishers are easiest to see.
  • Bring insect repellent and quick-dry layers and confirm with a ranger or guide about tide and weather conditions before entering mangrove channels - parts of the park are remote and services are limited, so rely on a local operator for logistics.
