The Oak Cove Trail in Calero County Park is a 5.6-mile out-and-back trail open for mountain biking, hiking, and trail running. The trail offers a mix of flat sections and gentle hills, making it accessible for beginners and families. Riders can enjoy scenic views of the reservoir and surrounding landscapes. The trail connects with the Lisa Killough Trail, allowing for extended rides within the park. While the path is mostly flat, there are a few small hills that may require less experienced riders or kids to dismount. The first hill at the beginning (and the last hill on the return) is probably the most challenging.
