Climbing the Flatirons

Location Colorado

Season Spring, Summer, Fall

Difficulty Varies

Duration 1 Day


The Flatirons are known for their famous east face slab routes on sculpted sandstone. Some of the classic east faces have over 1000 feet of climbing. Many climbers consider the Flatirons as a whole to be one of the best beginner resources in the country. Peek around the flanks and back sides of the flatirons and hiding in the woods are hundreds of steep, satisfying climbs. Once you are up in these enchanted forests, it’s easy to forget how close you are to Boulder and Denver.

The Flatirons have a number of routes that we would consider “Grade I.” Grade I Climbs are a series of short routes, a medium length multi-pitch climb, or some similar combination that can be completed in eight hours or less. Routes are chosen based on your ability and goals. Prior climbing experience or prerequisite instruction is required.

For climbers seeking more advanced routes with significant technical approaches and complex descents, or just a longer day of multi-pitch climbing, we offer Grade II Guided Rock Climbs in the Flatirons. Many climbs on Redgarden Wall fall under this designation, as well as other select climbs in the Boulder region. Previous multi-pitch climbing with Jackson Hole Mountain Guides and/or significant previous multi-pitch climbing experience is prerequisite.

Guided Climbs Level I:Price:  $400 private; $275/person for two
Guided Climbs Level II:Price:  $425 private; $300/person for two

Please call for pricing for 3 or more.

Conditions can be favorable for climbing at nearly any point during the year, but for most objectives, better climbing conditions occur in spring, summer, and autumn. Spring has a higher likelihood of precipitation. Summer afternoon temperatures can climb into the 90’s and isolated afternoon thunderstorms are common. In the autumn, climbers tend to find the most reliable conditions. Winter has many spells of great climbing weather, but it is difficult to plan in advance, as the Front Range can also receive full Rocky Mountain snowstorms and cold fronts. Because cliffs are dramatically affected by sun and wind exposure (or lack thereof), please refer to your JHMG guide for route or area recommendations. Suggestions are to provide our guests with the most enjoyable experience.

During summer months, even if the day dawns clear, all climbers should pack a rain jacket for the occasional surprise afternoon thundershower. Synthetic clothing is strongly advised at many times of the year, and is almost always preferable to  cotton. Comfort levels can vary quite a bit depending on where you are climbing within a given climbing area, so please ask us for our clothing recommendations based on your planned climb/class and if you are unfamiliar with the area. It is common for us to suggest an early start to avoid afternoon thunderstorms.

For your safety and comfort, bring synthetic and or natural fiber clothing for insulation. Cotton is NOT recommended and down must be kept dry. Clothing should be able to layer without encumbering your movement.
