This trail starts from the intersection with Stripe Rock Loop, climbs along the creek part way, before splitting of and ending at a junction with North Fork Springs Loop Trail.
This is a nice and wide dirt singletrack trail that offers access to the many climbing routes of the City of Rocks preserve via side trails. The North Fork Circle Creek Trail is well-signed so keeping on track should be easy.
This trail can be linked with others in the park to make for an all-day excursion. There are abundant and beautiful views throughout the park, and if you're interested in watching rock climbers, just take a seat and look up.
