Go rock climbing with IMCS on Saturday September 24th to stay in shape for the fall rock season. More details on the Upcoming Specials page.


For over 30 years we have been guiding folks and teaching them the skills to be safe and proficient in the mountains. Mount Washington is our training ground, home of the ‘World’s Worst Weather’. And with world class climbing locations such as Cathedral Ledge, Whitehorse Ledge, Frankenstein Cliffs, and Cannon Cliff; we can teach you the skills you need to enjoy the mountains for years to come whether you’re a raw beginner or seasoned expert.

Our guides and instructors grew up on these cliffs; IMCS knows which climb will be the best for you and how to get the most out of your climbing day.
