Completed in 1966, Kaeng Krachan Dam blocks the Phetchaburi River, creating a huge lake covering 45 sq. k ms, complete with small wooded islands. The lake is home to many fish and bird species, and is a popular spot to sail or picnic on the bank. Boat trips can be organised at the park office. A Thai restaurant overlooks the reservoir.

Get back to nature and small the flowers at Thailand's largest national park (2,915 sq. k ms.) where a rich rainforest covers rugged mountains along the border with Myanmar. Besides the wide variety of flora and fauna, Kaeng Krachan is heaven for birdwatchers with over 400 species identified. Hire a guide to show you the elephants, tigers, leopards, bears and other animals in residence.
