Bike Your Park Day: Bring your mountain bike and helmet to experience some of the 41 miles of trails at Hobbs State Park during Bike Your Park Day! Most of our trails are for beginners, but none are paved. Even after some rain, our trails are usually not muddy. Stop by the Visitor Center for a map and trail suggestions, and after you’re done check back in, take our survey, and pick up a free prize. Enter the drawing for a free bike jersey and other prizes!
