Khao Yai National Park is only about 205 kilometers from Bangkok. There are 2 ways of getting there; from the 56 kilometer marker of Mitraparp Highway, turn onto Thanarat Road and proceed for approximately 23 kilometers or at Hin Kong intersection, turn onto Highway No. 33 (Nakhon Nayok-Prachin Buri) and proceed to the Noen Hom intersection and take Highway No. 3077 to the park. The second route is rather steep and is more suitable for the return trip.

If traveling by bus, get off at Amphoe Pak Chong and continue on a mini-bus up to the gate of Khao Yai National Park. The fare is 15 baht and services are provided between 6 a.m. and 5 p.m. From there, visitors should flag a passing car to the park office or rent a car directly from Pak Chong. The park fee for an adult foreigner is 200 bahts and a foreign child is 100 bahts. The fee for each car is 50 bahts.
