SSC is one of the best organizations that I have had the pleasure of working with. I can confidently say that they are incredible at making climbing and climbing education more inclusive and accessible to all in a very unique way. Their guides are super knowledgable in the techniques and skills they teach, but also work beyond these aspects to foster a safe and supportive environment to optimize learning, safety, and fun. If you’re looking for the space to find education, support, reflection, respect, and a kickass time, any SSC event is the place!

A holistic approach to climbing, including insightful conversations around improving mental game, manage fear, and nourishing our bodies. I love the She Sends community. It’s been such a safe, supportive space to learn and grow as a climber.

All I can say is WOW!!!! Meg was such an amazing teacher/guide and was able to manage a group of 3 well enough where it made it feel like a 1 on 1 experience. I would definitely recommend this course if you are looking to expand your knowledge!

I had such a fun time climbing with our She Sends Collective guide, Chelsea! We hired her for two half-days of climbing while on vacation, and it was one of the highlights of our trip to Colorado. She was patient, flexible, and took the time to understand our needs in addition to being knowledgeable about what climbing would fit us in the area. She was also willing to set up routes for us that we side-eyed leading, which unlocked some more difficult yet fun new climbs. Added bonus is that Chelsea is a lovely human being, so we had a great time together.

In addition to this awesome experience, She Sends Collective’s commitment to inclusion was obvious in all interactions with Chelsea. There’s sometimes a bit of anxiety going into experiences like these as a member of the LGBTQ+ community, but that was absolutely not the case with this organization or Chelsea. The whole experience was top notch, and I couldn’t recommend She Sends Collective more!

      • An experienced, local rock climbing guide with extensive knowledge of the area
      • Full day of rock climbing in the Flatirons (6-8 hours) depending on your chosen itinerary

    What’s not included:

      • Transportation to the trailhead
      • Accommodations
      • Lunch
      • Guide gratuities — optional
  • If you can climb a ladder, you’re good to go. Being in good shape is always a plus but far from necessary. Rock climbing is all about using good movement technique rather than muscling up a cliff using brute strength. To ensure you have a fun day, your guide will choose routes that best suit your skill and fitness level—whether you’re a complete beginner, want to make a transition from indoor climbing, or have some experience and want to become a better climber.

    If you’re a climber with more experience looking for a challenge (including climbing multi-pitch routes), check out this all-women weekend climbing camp in Colorado.

  • No prior experience is necessary. Whether you’ve never donned a harness or you’re a seasoned climber, a guide will help you meet your individual objectives. Above all, your instructor’s number one priority is your safety. As long as you listen to the given instructions, you’ll succeed in making some progress—or completing a route.

    Flatirons boast plenty of options for beginner climbers. Whether you’ve never climbed before or are transitioning from the gym to outdoor climbing, your guide will customize the day to suit your skill level and objectives. With a guide by your side, you’ll learn something new, stay safe on the rocks, and most importantly, have fun!

    If you’re an intermediate climber, your guide will discuss your objectives and customize the day to your goals. Let your guide plan the day so you can focus on developing your skills while climbing some classic routes in the Flatirons.

      • Ropes

      • Climbing hardware (quickdraws, cam devices, stoppers, etc.)

    Once you and your guide agree on the details of your itinerary, your Flatirons rock climbing guide will suggest the best time (some time in the morning) and place to meet, whether that’s at the guide shop in Boulder or a predetermined location near the climbing routes. The guide will choose the appropriate terrain dependent on conditions and the ability of the group.
