Mammoth Climbing Guides is a small guide service located in the Eastern Sierra Nevada Mountains of California. Our focus is unparalleled customer experience, education, training, custom trips, fast and light ascents, and climbs that can be accomplished in one day.

Why Climb with MCG?

Intimate knowledge of the area: MCG guides live, work, and play in the Sierra Nevada. We have climbed all the routes we guide and know the range very well.

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.

Highest level of guide certification and training: All MCG guides have been trained and or have passed rigorous guide assessments that are nationally recognized adhering to the highest levels of industry standards, safety, and best practices.

Dedication to providing unparalleled customer experience: MCG believes in sharing our passion, experience, and knowledge of climbing while being in the mountains. We want our clients to have the best experience possible and our goal is 100% customer satisfaction.

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. The atmosphere we provide enhances the client experience, learning, and over all outcome at the end of the day. After all we want you to have the best time on the rock and come back for more!
