Guidebooks:
The official guidebook published by the Colorado Mountain Club is:
Colorado Trail: The Official Guidebook (7th Ed.)
Most hikers carry the much smaller databook, which contains information about camping, water sources, and trail distances:
The Colorado Trail Databook (4th Ed.)
Maps:
The official guidebook contains basic maps, but the quality is poor. If you leave the trail, these maps won't help you find it again. There are two choices for higher quality maps:
National Geographic Trails Illustrated
The Colorado Trail 2008 Map Book
Options for Resupplying:
1. Hitchhiking into towns
Most thru hikers resupply by hitchhiking into town to buy food or pick up their mail drops. Paul Magnanti's website has a detailed description of resupply locations and the best way to reach them.
2. Leaving food caches
An alternative approach for the Colorado Trail is to plan and leave food caches ahead of time. We packed eight bear cans with food and supplies, and left these in four locations, spaced about six hiking days apart. There are pros and cons to this method. It saves you from spending days hitchhiking, but it requires more planning, many bear cans, and hundreds of miles in the car. If you take this method, please note that it is not okay to leave a bunch of flimsy Rubbermade bins in the forest. Bears will find your food and eat it. All.
