"Central Park is in Khon Kaen Zoo. This crag is on your right, 1.6 km from the front gate. You will see the metal gate (normally open) to the dirt road. Require high clearance truck to get on the dirt road. Boulders are close and some can be seen from the dirt road. We have noe put a trail head sign on the metal gate"
When you arrive at the gate of the zoo area, you will be asked to pay an entry fee ฿150 (~5€). Besides bouldering, this fee gives access to all the great amenities the zoo has to offer including restrooms, restaurants, accommodation, campground, water park and the zoo itself of course!"
