Where in Colorado are you from? There are a bunch I really cant recommend just one. There are a few that I do in the winter to bring some challenge to the trail. Here is a forest website that has them broken down by ranger districts. I am near the canyon lakes ranger district. Did the old flowers road this last weekend. It took all day but didnt camp just was a day trip. That bunce trail is cool. Like the other fella said. It has an old plane crash that you can walk around in and see it just sprawled out there. Around red feather. You get alot of atv traffic on those trails being so close to town but you can normally get away from them the higher you go. The ones around idaho springs and central city are cool too. You come across alot of mining history
