Trails Explored

White Rim Trail, Canyonlands, UT, 1998
These are the trails TC and I have tackled over the years. We've run lots of trails in Colorado, where I live, as well as Moab, Utah. Some day I'll venture to other states but there are plenty of four wheel drive trails yet to explore here in Colorado.

Trail Books

If you want to explore the trails above but you don't have Charles Wells' fantastic back country trail books, I highly recommend you check them out. 
They give you all kinds of detail about the trails, how to navigate them and not get lost, you get GPS coordinates, difficulty ratings, off-road driving tips, maps, and more. 
The trails are listed by region, difficulty level, and are also listed alphabetically. 
I've used the two Colorado and one Moab, Utah books for several years now (all first editions).
