This trail has just about everything you'd want in a trail. As you traverse this rolling hillside, expect heart-racing obstacles, off-camber sections, deep ruts, and big rocks. If camping is your thing, Barbour Fork provides top-notch sites with established fire pits. Since it wasn't easy to get past these obstacles, you might have the entire place to yourself. Factor in the vast swaths of Aspen trees; this trail might be your go-to high-country fall leaf-peeping zone. Either bring the tent and stay the night or leave in the morning or even afternoon and still be home in time for dinner. Barbour Fork is one of those trails close to Denver that has it all!
