Khao Kho is made up of mountain ranges to northwest of town
about 1,174 metres above mean sea level covered in the main
by deciduous plants. Very cold during November-February, it
once was the base room which communist insurgents conducted
their struggles against the authorities during 1968-1982.
Today it is accessible via two routes; off Highway No. 12
(Phitsanulok - Lom Sak) at Ban Camp Son with a further distance
of 30 kilometres of off highway No. 21 at Ban Na Ngua, about
13 kilometres from town with a further distance of 30 kilometres.
Both routes wind through considerably steep terrain. Interesting
places include various viewing points, remains of communist
bases and buildings, war memorial, arms museum, a Chedi containing
Holy Relic and the Si Dit waterfall.
Nam Nao National Park is localted in Nam Nao
District at Km. 49-50 from Lom Sak to Chum Phae on Highway
no.12, conneting the northern and northeastern regions. It
covers the area of around 966 square kilometers or 603, 750
rais in Lom Sak, Lom Kao in Phetchabun and Korn Sarn in Chaiyaphum.
THe park seems to be the border between the North and the
Northeast of Thailand, especially when you go across Pho Khun
Pha Muang Bridge, or Huay Tong Bridge, which is the highest
Bridge in Thailand. Next to that part, there is a cliff with
red stone layers, which is called Pha Daeng, or Red Cliff.
The highest peak is called Phu Pha Jit, which is the origin
of Pasak, Pong, Loey and Cheee River and the shelter for several
kinds of animals.
