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.

Lost Valley (St. Charles Area) (Weather)
From redline9k: Been said, but definitly not green as posted 7/4. 10-15 mudholes on the upper singletrack thar are being bypassed and widening the trail, greasy in sections elsewhere, id call it 80% good. Please be careful about trail damage around the mudholes.
Katy Trail (Gravel Routes) (Weather)
From mhayes: It's 5 feet from going under but totally dry. Just don't stop or the mosquitos will carry you off. If you would get a flat, just throw the bike in the ditch and run.
Hamburg Trail (Gravel Routes) (Weather)
From mhayes: It's dry and good to go
