Erawan National Park
65 kilometres from Kanchanaburi along Route 3199, this 550-square-kilometres national park is the site of the 7-tiered Erawan Waterfall, widely regarded as being one of Thailand's loveliest cascades. A mountainside forest setting incmudes dense bamboo groves which support numerous bird species. The park's other major attractions is the spectacular Phra That Cave which contains monumental stalagmites. Bungalow accomodation and camping facilities are available.
Sri Nakharin Dam
69 kilometres from kanchanaburi, and just 4 kilometres north of the Erawan National Park, this massive structure marks the southermost extremity of an extensive reservoir, which is part of yet another national park.
Sri Nakharin National Park
This park covers 1532 square kilometres. Park headquaeters are 105 kilometres from Kanchanaburi. Major park attractions include the lovely 7-tiered Huai Mae Klamin Waterfall, boats trips on the scenic reservoir, and encroaching deciduous forests and bamboo groves where kingfishers, parrots, bee-eaters, hornbills, thrushes, wood peckers, babblers and numerous other bird species are readily seen. Larger, more elusive animals within the park's remoter areas include deer, elephants and tigers. Phra and Niramit Caves near the park headquarters compromise other attractions. Bungalow accommodation is available.
The park's relative inaccessibillity necessitates either a punishing 40-kilometre drive along a dry weather track, and negotiable onlt by motorcycle, pick-up trucks or 4-weel-drive vehicles, or a 45-75 minute boat ride from the Ta Kradan Pier 24 kilometres north of the Sri Nakharin Dam.
