Takasakiyama Monkey Park is located at the base of Mount Takasaki, a 628-meter-high (2,060-foot) mountain along the coast between Beppu and Oita City. The park is home to 1,500 wild macaques, which clamber down to an area in the park to play with the swings, slides and ladders—and, of course, to get fed. Visitors can get close to the monkeys, though not touch or feed them, and avoiding eye contact is recommended. A mini-monorail carries guests to the top of the mountain for an extra fee, and the Umitamago Aquarium, with penguins, dolphins, seals and otters, is also nearby.
