By public transport, take a train from Bangkok’s Krung Thep Aphiwat terminal or a bus or minivan from Mo Chit to Pak Chong, on the main line and highway to the north-east; either takes two and a half to three and a half hours. From Pak Chong, songthaews run along Thanarat Road as far as the northern park gate during the day, but not beyond it: the visitor centre is another 14 km uphill.
That last stretch is why most visitors come with a tour or a private car, or stay at a guesthouse that includes transport in its wildlife trips. Self-drivers will find the roads good; the southern gate, in Prachinburi province, is the nearer one for Haew Narok.

Getting around Khao Yai
Inside the park distances are long — it is over 40 km from the northern to the southern gate — and there are no buses. Options are a guided tour vehicle, a rented car or scooter from Pak Chong, or cycling for the fit: the road is quiet but climbs steeply. Drive slowly, especially at dawn and dusk, and give animals priority.
