The trail system is open to all user groups, with the exception of horseback riding. However, the trails located within the Erie Singletrack trails at Sunset Open Space were specifically designed for downhill bike usage. Hiking and trail running are highly discouraged in these areas as bikes are often traveling at high speeds and can quickly approach any other users and pose safety hazards. Bikers have the right of way at all times on these trails. The trails located at Sunset West Trails (located to the west of the singletrack trails) are better suited for trail running, hiking, and dog walking.
