Mountain Biking Bear River State Park

This is a ladder type network with roughly parallel trails lying low along the river and high atop the mesa with "rungs" connecting. It is mostly novice, but there is some exposure on the lower trail, and a couple of the rungs are steep, with one having launchable features.

    Accesible from Evanston's Bear River State Park, Rio Oso is a network of multi-use, single-track trails for hikers, runners, and mountain bikers. With views of the Uinta Mountains and the Bear River, Rio Oso is one of Evanston's hidden gems. The carefully maintained trails provide something for everyone, from gentle rolling terrain to heart-pumping climbs, technical descents, and even a pump track. A trail map is available through the following link: https://brorayurts.org/rio-oso

    There is some great novice riding to be had here, and some of the trial next to the river is quite nice. There's not a lot of mileage, so you can hit everything in an hour or less, but it may be worth doing extra laps on the funner downhill runs, especially since they're short.
