Climbing the Flatirons

Location Colorado

Season Year-round

Difficulty Varies

Duration 1 Day


Jackson Hole Moutain Guides takes pride in offering guided climbs of the Flatirons. Nestled into the hillsides south of Boulder, CO, these angled plates are known for famous east-facing slab routes on sculpted, red sandstone. With over 1,000 feet of moderate climbing, the Flatirons host the longest and best beginner multi-pitch climbs in the country! In addition to the moderately angled east faces, hundreds of steep and unique climbs hide among the trees on the flanks and backsides of these behemoth rocks.  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 different routes, although most are medium-length, traditionally protected multi-pitch climbs. In general, trips last eight hours, and routes are chosen based on your ability and goals. Prior multi-pitch climbing experience or instruction is required to participate in our Group Climbs.

Every Monday throughout the fall.

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.
