Haew Narok sits within Khao Yai National Park, one of Thailand's oldest and most-visited national parks, and is notable for its series of cascades plunging through evergreen forest. The name Haew Narok can be translated as 'Hell's waterfall', a reference to the steep cliffs and roaring torrents.
Access to the main viewpoints involves a maintained trail and a set of steps, with several lookout platforms offering different perspectives of the falls and surrounding valley. The area around the fall is typical of Khao Yai's evergreen and mixed deciduous forest, home to birds, macaques and other wildlife often seen from the paths.
