Lake Mercer Park Loop offers an enjoyable hiking and bike experience with its combination of paved and gravel paths. You’ll find occasional side trails that lead to the lake by dirt paths, all boasting stunning views. This easy trail features several potential exit points near residential areas. As of 2025, T-Mobile users may experience low but existing cell phone coverage, here. Among the points of interest are a couple of bridges crossing creeks, the lake itself, a large dam, and facilities conveniently located near the parking area. This trail attracts hikers, cyclists, and joggers alike. If you decide to bring your dog, be sure to keep it leashed at all times, as per park regulations, as there are other dogs. This loop is perfect for testing out new gear and for core strength training in preparation for larger trips.

The creek’s banks are often lined with a mix of mature trees, and some interesting rock formations along the water's edge, worn smooth by years of flowing water.

Lake Accotink is a 55-acre reservoir situated along Accotink Creek. There are a bunch of trails around the lake (some paved and some dirt/gravel), and the Cross Country Trail through Lake Accotink Park is perfect for running.
