Although Khao Kho is situated in Petchaboon, many tourists rather go via highway No. 12 (Pitsa Nulok – Lomsak). This is because of breath-taking views and a number of tourism locations along the road to stop at for both natural beauty and enjoyment. Keep driving until you reach the 100th milestone (Khaem Son – Khao Kho junction) which is considered the green route to Khao Kho with amazing sceneries and attractions.
