Muddy trails are easily damaged by foot, bike or horse traffic. During Colorado’s muddy spring season, Hartman Rocks and Signal Peak trails are sometimes closed to bike and horse traffic. Runners and hikers are still permitted, but are encouraged to use the trails early in the morning when they are still frozen and not muddy yet. Help keep our trails healthy by staying off trails until they are dry! Obey posted signage at trailheads and on roads.

The entire Signal Peak trail system is closed to mountain bikes Jan. 1-April 30. Bikes are not allowed on the trails before 10 a.m. from May 1-15.

The entire Signal Peak trail system is closed to all motorized traffic Jan. 1-May 15.

The northwest part of the Signal Peak trail system is closed to motorized and mechanized traffic from March 15-May 15. Hikers and runners may not use the trails before 10 a.m. during this time.

Closures do not apply to the campus trail system, which includes the following trails: Canal, Contour Connector, west segment of Contour, Old Car, Zig Zag, the exercise trails and the flow track. View the Signal Peak trail map below for more information.
