Devil’s Gate Interpretive Site

For a good view of the Martin’s Cove visitor center, the former Sun Ranch headquarters and the reconstructed Fort Seminoe, visit the Bureau of Land Management’s interpretive Devil’s Gate turnout near mile marker 57 on Wyoming Highway 220, about 60 miles southwest of Casper or 12 miles northeast of Muddy Gap. The turnout, on the north side of the highway 5.8 miles southwest of Independence Rock, offers a magnificent view of the Sweetwater Valley and a paved walking trail with interpretive panels about the vivid and well-documented history of the area. Emigrant trail ruts are visible from the pathway.

Due to a quirk of topography, however, Devil’s Gate itself is not visible from the turnout. To see the gate—or to climb it and view the many carved pioneer inscriptions, especially on the east side of the gate—ask for directions at the Martin’s Cove visitor center. Devil’s Gate is located on Wyoming state land and is always open to the public.
