Herbert Glacier is a remote Alaska tidewater glacier near Juneau, drawing visitors with its sweeping ice fields, dramatic mountain scenery, and rich wildlife.
Herbert Glacier flows from the vast Juneau Icefield, one of the largest temperate ice masses in North America, and has carved a broad U-shaped valley over thousands of years. The glacier has retreated measurably over the past century, leaving behind polished bedrock, kettle ponds, and a braided river system that geologists use to study glacial dynamics in real time.
The Herbert Glacier Trail runs roughly five miles round trip from the Glacier Highway trailhead, climbing gently through old-growth Tongass forest before emerging onto an open gravel outwash plain. The final stretch brings you face-to-face with the glacier terminus, where seracs of milky blue ice calve into a shallow meltwater lake. Interpretive signs along the route explain the ecology of the surrounding forest and the glacier's movement over time.
Wildlife is a consistent presence throughout the valley. Bald eagles perch in the canopy above the river, Dolly Varden trout hold in the cold pools, and black bears are regularly spotted on the slopes above the tree line. The Tongass old-growth adds its own drama, with massive Sitka spruce draped in moss creating a cathedral-like approach to the ice.
Nearby, Mendenhall Glacier offers a complementary glacier experience with visitor center facilities, making the two a natural pairing for a full day of exploration in the Juneau area. Herbert Glacier remains the quieter, wilder alternative, and that contrast is precisely what makes it worth seeking out.
Visit in late May or June when snowmelt keeps the trail accessible and wildflowers line the forest path.
Wear waterproof boots, as creek crossings along the Herbert Glacier trail can be ankle-deep even in summer.
Bring binoculars to spot black bears foraging on the valley slopes, especially in early morning.
Start the hike before 9 a.m. to have the gravel bar and glacier views largely to yourself.
Pack layers regardless of the forecast, since temperatures near the glacier face drop noticeably even on warm Juneau days.
