We conduct our courses at a variety of different areas including Cathedral Ledge, Whitehorse Ledge, Cannon Cliff, Frankenstein Cliff, Mount Willard, and Mount Webster. We specialize in winter ascents of Mount Washington, including routes in Tuckerman Ravine and Huntington Ravine.

Synnott Mountain Guides has several highly qualified guides, so whether you're looking for a sunny day of multi pitch rock climbing at Cathedral Ledge, a day of ice climbing in Crawford Notch, or an introduction to mountaineering on Mount Washington, we have the expertise and local knowledge for your mountain adventure.

Spring in the White Mountains

Spring is a time of transition in the White Mountains. We still have great conditions on Mount Washington for backcountry skiing, mountaineering, and even some remaining ice climbing opportunities. Off the mountain, we have opportunities to rock climb as well. Check out our featured courses/trips below or visit the full range of Mountaineering, Ice & Mixed Climbing, Backcountry Skiing & Ski Mountaineering, and Rock Climbing options. You can book online directly on the course/trip pages or contact us via phone or email to start your adventure.
