The Eagle Cliff Trails is an extensive network of marked trails in the Black Hills National Forest that are popular for biking, hiking and cross-country skiing. Totaling more than 20 miles, the trail system can be used to customize trips of varying distances and difficulties. The terrain covers lots of rolling hills that can provide some challenging rides. There are multiple trailheads and access points so the trip options are abundant. The trail surfaces and conditions will also vary with some possible muddy sections and obstructions along the way. This loop ride covers an intermediate 5-mile loop but for riders exploring a lot more of the area, pay attention to signs and distance covered to ensure you can get back to where you started before wearing yourself out too much.
