Sangay can and has been climbed. It was first ascended in 1929 by Robert T. Moore, prior to its current eruption beginning in 1934. However, the volcano's current active state presents dangers to mountaineers in the form of falling ejecta; in 1976, two members of an expedition on the volcano were struck and killed by falling debris. In addition, the volcano is located in a remote region with poor roads and is difficult to access, and periods of heavy rainfall can flood rivers and cause landslides, rendering the mountain routes impassable. Nonetheless, the Instituto Ecuatoriano Forestal y de Areas Naturales, which maintains an office near the mountain, facilitate such activities by providing local guides and rooms for rent to visitors. Ascension takes between 7 and 10 days from Quito. Conditions on the volcano are usually very wet and foggy, which may impair visibility significantly during the ascent.
