The Wolverine Creek Trail is part of a series of mixed-use trails in the Kelly Canyon area. This is a narrow doubletrack that does see ATV use during the summer. The trail is primarily all hard-pack dirt that can get dusty during the dry season. The trails have banked corners, as well as lots of ATV speed bumps which are great on a mountain bike.
The best access from this trail would be to incorporate it into a larger loop utilizing the other trails in the area. But an up and back off of the River Road makes for a great leg burner up, with an even greater downhill run.
