Death Hollow, Canyon within Canyons of the Escalante, Utah, United States

Death Hollow is an 8-mile (13 km) slot canyon in Grand Staircase–Escalante National Monument, southeast of Boulder in Garfield County, Utah. It is a side canyon of Horse Canyon, which continues on to the Escalante River. The canyon lies east of the Escalante River and is distinct from the longer, deeper Death Hollow upstream near the town of Escalante.

In the late 1800s, mail carriers traveled through this canyon on a route that connected settlements across the region. The Boulder Mail Trail served as a critical communication link between isolated communities.

The canyon lies within Grand Staircase–Escalante National Monument, established in 1996. Its name, Death Hollow, is shared with a longer canyon upstream near Escalante town, so hikers should check which one a route refers to. The side canyon is reached from the town of Boulder.

Visiting this canyon involves a multi-day hike with sections requiring stream crossings and careful footing on uneven terrain. Bring appropriate gear for extended backcountry travel and plan for the possibility of getting wet.

Death Hollow is often confused with the longer, deeper canyon of the same name that lies upstream and directly east of the town of Escalante. This 8-mile (13 km) canyon instead sits southeast of Boulder and drains into Horse Canyon, which continues to the Escalante River.
