7–8 hours
Moderately fit: able to walk on uneven icy terrain for several hours and handle short steep sections.
Drive the Glenn Highway to stand on one of the largest car-accessible glaciers in the U.S. This full-day winter hike combines hands-on crampon time, geology lessons from experienced guides, and striking blue-ice photo opportunities.
You step off the van with your breath fogging, the Glenn Highway already slipping behind you like a ribbon of black. Ahead, the glacier waits—an enormous river of blue and white that pushes through the valley, not static but alive, cracking and sighing as snowpack and pressure reshape its surface. A guide checks your crampons, points to a crevasse rim a few dozen yards away, and for a few heartbeats the landscape feels both brutal and intimate: raw ice underfoot, wind that seems to test your intent, wide skies that make everything feel immediate.

Bring a breathable base layer, insulating mid-layer, and a waterproof outer shell—temperatures and wind can change quickly on the ice.
Use UV-blocking sunglasses and high-SPF sunscreen—the ice reflects light intensely even in low winter sun.
Waterproof, insulated boots with stiff soles are required for crampon fit and warmth on the glacier.
Store batteries and phones in an inner pocket to prevent rapid discharge in cold conditions.
Matanuska has long been part of Athabascan territory and later attracted miners and scientists; its movements store climate history in ice layers.
Groups are limited and guided to reduce impact; follow Leave No Trace principles and avoid disturbing ice formations or depositing litter on the glacier.
Keeps feet warm and provides a stiff sole for crampons.
