🧱 Direct East Face – First Flatiron
This classic route is both long and sustained, requiring diverse techniques from face climbing to cracks. The exposure can be intense, but the beauty and flow of the climb make it a must-do for experienced adventurers.
🪨 Advanced Bouldering at Flagstaff
Flagstaff Mountain also offers some of the hardest bouldering problems in the area. These climbs are short but powerful, often requiring precise movements, body tension, and a lot of trial and error. For many climbers, the challenge is addictive.
What Gear You’ll Need
Climbing is safer and more fun when you have the right equipment. If you’re just starting out, here’s a quick checklist of essentials:
Climbing shoes – Choose a pair that fits snugly and gives you good contact with the rock.
Harness – Make sure it’s comfortable and rated for the type of climbing you plan to do.
Helmet – Always wear one outdoors—it protects you from falling rocks and unexpected bumps.
Belay device + locking carabiner – For climbing with a partner and managing the rope safely.
Chalk and chalk bag – To keep your hands dry and your grip strong.
Rope – If you’re lead climbing or doing multi-pitch routes, you’ll need a dynamic rope rated for the climb.
Clothing – Lightweight, flexible layers work best, especially in Colorado’s changing weather.
