Why Climb with MCG?

Small course sizes and guide to client ratio: MCG believes in keeping course and trip sizes small to maximize the learning and experience of our clients. This gives customers more one on one time and enhances the quality of the trip.

Foster the Guide/Mentor relationship with clients: We believe in providing your first climbing experience to show you the “ropes” and will continue to guide you along through your climbing career. MCG takes great pride in facilitating the growth of our client’s knowledge, skills, and experience.

Attention to detail and safety: Our number one goal is to keep clients and ourselves safe. With our accumulated knowledge of the area and awareness of conditions we know where to go and when. All of our guides have been trained and or certified in climber self rescue and posses the necessary medical certifications.

Value and Quality: We keep our rates very competitive and are continually improving the products and services we offer.

Custom climbs and courses: MCG can customize any climbing training, course, or climb you need. If you don’t see what you need, contact us to make arrangements.

Fun, relaxed, supportive, inclusive, low pressure learning environment: Above all else climbing should be fun and enjoyable.
