About the Park
Travelers on Interstate 80 near Grantsville can pull off at the Grassy Mountain eastbound rest area, which includes a fenced off-leash dog spot. The enclosed area lets dogs stretch and run safely away from highway traffic, with a bench for owners and a waste station to keep things tidy. It is open 24 hours, so it works for late-night or early-morning stops crossing western Utah. This is a highway rest-area amenity rather than a destination park, best used as a quick break on a long drive across the Great Salt Lake Desert. The surrounding terrain is dry and exposed, so bring water for your dog, especially in summer when there is little shade nearby.
