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.
The development and trail maintaince cannot happen without the help and support of our local community.  Please considering helping us by volunteering at one our trail day events or by making a donation by following the paypal link below.  Any amount helps us keep the trails in riding shape and allows for us to develop new trails.
