Grosvenor Arch, Double natural arch in Grand Staircase-Escalante National Monument, Utah, United States.

Grosvenor Arch is a natural sandstone double arch in Kane County, Utah, located within Grand Staircase-Escalante National Monument. The two openings sit side by side in the same rock face, with the larger arch framing a wide window of sky above the desert floor.

Grosvenor Arch is named for Gilbert Hovey Grosvenor (1875–1966), a president of the National Geographic Society, which published National Geographic Magazine. The sources record the naming but give no date for it.

The arch is named for Gilbert Hovey Grosvenor (1875–1966), president of the National Geographic Society, publisher of National Geographic Magazine. Visitors today reach it by the dirt Cottonwood Canyon Road, which runs through Cottonwood Canyon in the western part of the monument, and stop at the fenced site with its outhouse and cement benches.

A short, flat path leads from the parking area directly to the arch, so no special fitness is needed to reach it. The access road is unpaved and can become difficult after rain, so checking road conditions before setting out is a good idea.

The arch honours Gilbert Hovey Grosvenor (1875–1966), president of the National Geographic Society, publisher of National Geographic Magazine. A concrete sidewalk runs almost to the base of the arch and is wheelchair accessible, and the site has an outhouse restroom and cement benches.
