Perimeter Trail

This easy ~9 mile loop circles the entirety of the the reservoir.  The road across the top of the dam (Crest Trail) is open to hikers and bicycles, but not to horses. Horseback riders can use the lower trail below the dam. The Crest Trail is closed completely on waterfowl hunting days (Wednesdays and Saturdays from October through February). Visitors are ​not allowed on the dam face or on any irrigation control structure. Bicycles and horses are permitted on the main trails, but not on the boardwalks. Bicyclists are encouraged to use bikes with thorn-proof tires because the trails are not paved and thorns are prevalent. Dogs are not allowed in the refuge and they must be on a leash in all other parts of the park. No motorized vehicles are permitted on the trails. All trails are closed from 10 p.m. to 5 a.m
