After passing through the entrance just up the hill from Phu Ruea village and paying a 200 baht fee (for foreigners), visitors climb a steep and narrow road to the main visitor centre. Along with a giant digital thermometer and a display with several types of snakes kept preserved in large jars, a desk with an English-speaking ranger offers good info on the park, including maps and brochures. If you don't have your own wheels, a songthaew can be hired to take you up to the peak.
