Get in
Khao Yai is along the way from Bangkok to Nakhon Ratchasima (Korat). The nearest town to the north entrance is Pak Chong, which can be reached either via train or buses running between Bangkok and Korat. From here taxis, songthaews or motorbike hire can take you onto Khao Yai. The south entrance is about 13 km north of Prachinburi- Head north on the roundabout on Rt 3077. A road runs through the length of the park from the Pak Chong side to the Prachin Buri side. The park is an easy drive from Bangkok.
Buses regularly leave from Bangkok's Mo Chit bus station to Pak Chong (terminating in Korat)- the journey takes about 3-4 hours and costs 150 baht each way (March 2014). Minibuses to Pak Chong can be caught from Bangkok's Victory Monument.
Nearly all trains from Bangkok to Korat/Ubon go via Pak Chong, however this is much slower than the bus. This route also goes via Ayutthaya, which is halfway between Pak Chong and Bangkok and about a 3 hour journey (53 Baht, 3rd class no aircon, March 2014). When disembarking at Pak Chong follow the road to the high street and turn left to get to the centre of town.
