Trail to End of Root Glacier

Overview

If you want a true Alaska glacier experience without a mountaineering resume, this is the move. Starting in the historic mill town of Kennecott, the Root Glacier Trail rolls out easy-to-moderate singletrack before dropping through rocky moraine to the glacier’s toe. Count on roughly 4.0 miles round-trip to reach the ice and return; many hikers extend to 5–6 miles total if they wander on the glacier. Plan around 2.5–4 hours depending on pace and on-ice time.

Getting There

Reaching Kennecott is part of the adventure: drive the 60-mile unpaved McCarthy Road to the park footbridge and park for a fee. Private vehicles don’t continue past the bridge. From the footbridge, shuttle, bike, or walk about 5 miles up to Kennecott. The trailhead sits about 0.5 miles through the mill town. Cell service is spotty—download maps.

Route Snapshot

The path winds through brush and forest with occasional views. Around 0.4 miles, you’ll hit a junction with a pit toilet—continue straight for Root Glacier. At roughly 1.3 miles there’s a pretty waterfall (filter before drinking). Around 1.5 miles, the scenery blows open: big views toward Mt. Blackburn, Regal, Donoho, and the Stairway Icefall. From the signed “Glacier Access” turn, descend a short but steeper, loose section of moraine to the glacier’s edge. This final bit is the crux and takes extra time.

On the Ice

You’re allowed to step onto Root Glacier on your own. Do it only with traction (microspikes or crampons) and ideally poles—plain boots aren’t enough. Stay well back from the edges where ice is undercut by cold, swift meltwater. Expect low-angle exploring near the toe with sculpted runs, blue pools, crevasses, and the constant murmur of water under debris. Go with a partner, give any holes or moulins a wide berth, and turn around if surfaces look thin or fractured. Guided trips are available in town if you want instruction and gear.

Camp, Wildlife, and Trail Feel

Free, walk-in camping spots sit near the access just before the descent to the ice, with additional primitive camping farther along at Jumbo Creek. Bears frequent the area; travel in groups, make noise, and carry bear spray. You may also spot moose, Dall sheep, eagles, or even a lynx in the broader area. The trail itself is well trodden and popular in season, but the scale of the glacier keeps it feeling wild once you step onto the ice.

Best Time to Hike

June to early September is the sweet spot: roads and services are up, and the glacier surface is generally friendlier. Start early for cooler temps on the approach and softer light on the ice. After rain or hot spells, expect higher meltwater and a more dynamic (read: trickier) toe. Weekdays see fewer people than weekends.

Tips and Tricks

• Traction is non-negotiable for on-ice travel; poles help on the loose moraine.
• A small filter lets you top up at the waterfall around 1.3 miles.
• Check conditions at the visitor center or a guide shop in Kennecott before stepping onto the ice.
• Dogs are allowed on leash on the trail, but leave them off the glacier—too slick and crevassed for paws.
