Thailand's largest national park sits on the rugged Tanaosri mountain range
which separates Thailand from Myanmar, 115 km south of Bangkok and some 60 km
from Petchburi off Highway 3175.
The immense, 2,915-square-km park is known for its "Swiss Lake," wildlife, thick
rainforest, savannah grasslands, impressive waterfalls, and treks starting
from park headquarters at Kaeng Krachan Lake. One of the better hikes begins
at Km 30 and proceeds uphill to the summit of Mt. Panernthung, some 1,207 me
ters above sea level. Guides can be hired at park headquarters, three km
beyond the dam at the end of the road. Rafting tours on the Petchburi River
are also organized by park authorities. Another highlight is the falls, best
experienced during or shortly after the rainy season July-November. Pala-U is
an 11-tiered falls noted for the distinctive butterflies which claim different
levels: blue-green butterflies on the first level, brown ones on the second,
golden butterflies near the top falls. The 18-level Ha Thip Falls is five km
from Panernthung Peak, while Nam Yod Clif is on the banks of the Petchburi
River.
