Lan Sang National Park at a Glance

About Lan Sang National Park

Designated in 1978, Lan Sang National Park covers just over 100 square kilometres of fertile, high-elevation landscapes. It is best known for the Lan Sang Waterfall, a diverse variety of wildlife and its majestic pine forests. Visitors can join wildlife-viewing tours in hope of spotting rare species such as barking deer, flying lizards, wild cats and boar; the most cherished animal here is the elusive serow, a rare mountain goat only the luckiest travellers will glimpse. Birdwatchers have plenty to enjoy as well.

Pha Lad is an enormous slab of rock lying on the bed of Lan Sang creek, massive and striking when viewed through the clear water, with Lan Lieng Ma Waterfall a short walk away. Several other waterfalls lie within the park, the largest being Lan Sang Falls, the main attraction, dropping 40 metres over three levels; others include Pha Te and Pha Phung. All are best viewed between July and November, when it rains regularly.
