Rio Oso
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.
