Cattle grazing is only allowed in parts of the Swell that are not designated as such. The San Rafael Swell is also dotted with sections of land managed by the Utah School and Institutional Trust Lands Administration, as is much of the state of Utah. Goblin Valley State Park is on the southeastern edge of the San Rafael Swell. Recreation The San Rafael Swell attracts hikers, backpackers, horseback riders, trail runners and all-terrain vehicle (ATV) enthusiasts. Many steep, narrow slot canyons popular with technical canyoneers are found in the San Rafael Reef. The Eastern Reef is a possible destination for rock climbers. It is home to some of the longest and sandiest climbing routes in Southeastern Utah, and was, at least by one person, nicknamed the Sandstone Alps.
