Climbing Trips & Classic Climbs in Eldorado Canyon State Park

Eldorado Canyon State Park, or "Eldo" as it's commonly referred to, needs little introduction. This world class rock climbing destination is the crown jewel of Boulder and Denver. Thousands of single and multipitch climbing routes grace the canyon walls and hold a unique challenge for every climber. Tiny edges, intermittent cracks, and delicate footwork make for some of the best rock climbing in the world. Eldorado Canyon is jam packed with tremendous amounts of both single and multipitch rock climbing on beautiful, bullet hard Fountain sandstone.

No other destination in Colorado is so steeped in climbing history. Climbers began flocking here in the 1950's to explore the towering canyon walls and natural weaknesses that wind their way up the cliffs. Many famous climbers such as Layton Kor, Pat Ament, and Christian Griffith left their mark on the Boulder climbing scene with test pieces such as the Naked Edge, Supremacy Crack, and Paris Girl. Some of the countries hardest rock climbs were at one time established on the stunning multicolored canyon walls. Today, Eldo holds a challenge for beginner and expert climbers alike.

Climbing here in the canyon takes a little getting used to. Eldo grades can feel tough. The in-obvious traverses, tiny feet, and sometimes run-out nature of the climbing give into the reputation of being "sandbagged". Give it a few pitches though and you'll never want to climb anywhere else! Short approaches, incredible climbing, and a huge diversity in climbing grades make Eldorado Canyon one of the best places to climb on the Front Range and we can show you the classics, or the adventurous "off the beaten path" routes.


This is a great destination for both half and full day climbing trips. Many of the bigger, classic routes are considered full days. Half days are great for cragging, or shorter multipitch routes on the Wind Tower or Whales Tail. It's not uncommon to walk away from a day of climbing here with at least ten pitches under your belt. We guide many of the classics such as the Yellow Spur, Bastille Crack, and Rewritten. We also guide many other routes in the canyon. Contact Us if you've got another objective in mind and we'll make it happen.
