Diamond Ridge is home to two park areas with trail systems. One is the Homer Demonstration Forest, a preserve on the slopes just below the actual ridge itself.  It contains an arboretum, self-guided nature trails, and is one end of the Homestead Trail which crosses the demonstration forest, climbs up Diamond Ridge and across a deep valley to Crossman Ridge, eventually ending at the Homer Reservoir. In winter months there are extensive groomed trails for cross-country skiing, as well as a snowshoe trail.
The other park in the area is the Diamond Creek State Recreation Area. This is a newer unit of Alaska State Parks and has little development. It is day-use only, camping is not permitted, and the access road is steep and extremely rough in places; vehicles over 25 feet (7.6 m) are not permitted on the lower part of the road. The road leads to several parking areas for access to hiking and biking trails. The bike trails are constructed and maintained by a local cycling club.
