Pay your admission fee at the entrance of the park and follow the marked path, which will lead you up the side of the mountain. The climb is very steep, and it takes approximately 15 to 20 minutes to reach the top.
Heed the warning signs along the path. You may encounter some members of the wild macaque monkey troupe living in the park (there are more than 170 of them). Don't carry food in the open, don't get too close to the monkeys and don't engage them in any way. Don't even make eye contact, which some monkeys may perceive as a threat.
Make your way to the little cabin at the top of the mountain. Inside the cabin, you'll be able to purchase food to feed to the monkeys, which you can do through the wired windows. This is the only safe way to feed the monkeys and interact with them. Do not take the food outside.
