Klaeng, Coastal district in Rayong, Thailand.
Klaeng is a district along Thailand's eastern coast in Rayong province, covering several hundred square kilometers of farmland and seaside settlements. The area divides into 15 sub-districts with around 146 villages, with the main administrative center in Mueang Klaeng near the Prasae River.
The district became strategically important during the Ayutthaya Kingdom period as a gathering place for military forces in ancient Siam. This position made it a key location within the wider regional network of that era.
The name Klaeng comes from the Chong language word Ka-laeng, referring to the walking catfish that inhabits local waters. This connection shows how the district's identity ties directly to what people find in the sea and use for their livelihoods.
The area sits at low elevation with direct access to coastal beaches like Mae Phim Beach and Rim Pae Beach along the Gulf of Thailand. Plan for humid weather and visit during drier months for the most comfortable experience exploring the district.
The district is home to two popular beaches that attract local families and visitors seeking quieter seaside weekends away from crowded resort areas. These stretches of sand offer a less commercialized feel compared to busier beach destinations elsewhere in Thailand.
