The monkeys, also known as crab-eating macaques, are considered sacred according to the Hindu principle of Tri Hata Karana, which seeks harmonious relationships between humans, the natural environment, and God. This sanctuary strives to create peace and harmony for visitors from all around the world, and to conserve rare plants and animals used in Hindu rituals. There is also ongoing research for educational institutions into the interaction of the park's monkeys with one another and with the park's natural environment.

Visitors can wander paved paths through a swath of preserved jungle among many monkeys of varying dispositions. Some may clamor for your attention (and beg you to buy a banana from a nearby hawker), some may be disinterested, and some may fight amongst themselves. Follow the park’s posted guidelines (also found in helpful brochures) to avoid any monkey trouble. The well-trained staff will happily handle any issues that may arise.

and the grounds are quite beautiful. Between the monkeys, temples, and pavilions there are many photo opportunities. The temples date back to approximately 1350 AD. In the southwest corner is Pura Dalem Agung, the Great Temple of Death, used to worship the God Shiva. In the northwestern park is a "Holy Spring" bathing temple, Pura Deji. Pura Prajapati, in the northeastern corner, is used to receive the deceased in preparation for cremation.

Before you arrive, there are a few important details to keep in mind. There’s a small entrance fee of 25,000 IDR. Sacred areas of the temples are closed to tourists, but you can enter some areas while wearing Balinese prayer attire (sarongs with sashes). The monkeys have been known to steal belongings so take care — it’s best to stow away loose items and be extra careful with your phone and camera.
