Grosvenor Arch

Grosvenor Arch is a remarkable sight, a massive sandstone formation standing more than 150 feet high and spanning 92 feet across. The natural double arch is located within Grand Staircase Escalante National Monument, about ten miles southeast of Kodachrome Basin State Park.

The arch was named by photographers of the National Geographic Society during a 1949 expedition, in honor of the group’s president Gilbert Hovey Grosvenor. Often backlit by clear blue skies, the arch is one of the most photographed formations within the monument boundaries, and a testament to the powers of erosion.

Grosvenor Arch is poised at the end of a remote Henrieville sandstone ridge, yet still accessible. From Cannonville, head south for about nine miles to Kodachrome Basin State Park. Continue for another ten miles along a graded, unpaved section of Cottonwood Canyon Road to the turn-off for Grosvenor Arch.

A paved path leads from the parking lot about halfway to the arch for perfect viewing; a short hike along a dirt path leads to the base. A campground with basic amenities (restroom, shower, and picnic area) provides a respite beneath this rugged natural wonder.
