Topography
Erawan National Park was designated in June 1975, as Thailand's 12th National Park. It covers an area of 550 Km² of high mountains and attractive valleys. The eastern mountains rise to 996m. with shear limestone cliffs. These mountains protect the park from the eastern monsoon resulting in a low average rainfall.

Climate
These mountains protect the park from the eastern monsoon resulting in a low average rainfall. In summer the weather is sweltering but it is wonderfully between November-February cool.

Flora and Fauna
The main feature of the Park is the stunning Erawan waterfall created by a profusion of small streams joining together before tumbling down the precipitous cliffs. Deciduous forest covers about 78 % of the park with Pterocorpus macrocarpus, Hopea adorata, Afzelia xylocarpa and Spondias pinnata being some of the dominant tree species. There is also dipterocarp, dry evergreen and bamboo forest. Wildlife surveys of mammals, reptiles, birds and amphibians have been carried out. It you are lucky you may catch a glimpse of elephants, gibbons, Siamese hare, flying squirrels, eagles, white-eyes, king cobras or pythons. Fish, crabs and insect are abundant in the many streams.
