Chaloem Rattanakosin National Park

Chaloem Rattanakosin National Park is a protected mountain area in Kanchanaburi Province featuring mountains, caves, and waterfalls, with the Khao Kamphaeng peak rising to about 1,260 meters. The terrain offers multiple pathways to explore, ranging from easy walks to more challenging mountain routes.

The area was designated as Thailand's 17th national park in 1980 and has been a protected nature reserve since then. Archaeological findings from the late Ayutthaya period show that the region experienced long human settlement.

The park's name honors King Rama I. and links Thailand's natural heritage to the founding of the Rattanakosin dynasty. This royal connection gives the place cultural meaning for people visiting from across the country.

The park sits roughly 100 kilometers north of Kanchanaburi and is accessible throughout the year, with visitors able to hike trails, explore caves, and observe wildlife. Bring sturdy shoes and plenty of water, as paths can be steep and the jungle is dense.

The park is home to the rare barking tree frog, whose call sounds like a dog's bark and is something most visitors do not expect to hear. The Than Thong waterfall drops in roughly 15 successive tiers, creating a distinctive natural feature.
