Surili (Presbytis comata Desmarest) is one of the keystone species with Endangered status in Mount Ciremai National Park (MCNP). Surili is an arboreal primate with a high dependence on vegetation in its habitat. The high proportion of resting behavior of these animals causes the importance of information related to the characteristics of the surili sleeping trees. The purpose of this research was to identify the surili sleeping tree, the position selection behavior of the individual surili of saplings and adults, and the physical character of the location and distribution of sleeping trees. The method used a 10 meters diameter plot with the observation used Visual Encounter Survey (VES) method. The results showed that surili were four species of sleeping trees, including Trema orientale, Anisoptera costata, Castanopsis argentea, and Macaranga rhizinoides. The height of surili sleeping trees ranges from 16 - 36 m, the diameter range from 47.7 - 150 cm, and the tree architecture is diverse. Surili saplings have a higher about 0.30 meters than adult surili's average height of sleeping positions. Surili does not choose the tallest sleeping tree but tends to choose the tree with the largest diameter. During the observations, the locations of the sleeping tree have an average height of 1,622.49 meters above sea level with an average slope of 23.3% and no overlapping of sleeping trees between one surili group and another surili group.
