As a courtesy GORC provides the general community with easy-to-read printable maps of all the GORC-maintained trails in our area. We have performed trail design, construction or maintenance on almost all the trail systems listed. We use GPS mapping equipment and software which we then translate into a graphics editing program. We release maps and subsequent updates as they become available. Check back often for revisions.

Latest Trail Conditions

Lost Valley (St. Charles Area)
From JTP44: trail was +/-50% rideable IMO. Many places in phase two had standing water due to leaf litter not allowing trail to drain. Mud and ruts were present. needs days of sun and high winds to be worth riding. Gravel in the area was much better.
Castlewood State Park (St. Louis Area)
From OffRoadAddict: Everything north of Kiefer Creek Rd was amazingly dry with just a few soft/muddy spots where water hadn't drained off the trail. Did not ride south of road, it looked like it needed another day to dry
Greensfelder (St. Louis Area)
