You can walk up to a 100-foot wall of blue ice just 12 miles from downtown Juneau

It’s closer than you’d think

About 12 miles from downtown Juneau, a glacier the size of a small city sits at the end of a paved road. You don’t need a guide, a permit, or a helicopter.

You just drive out, park, and walk. The Mendenhall Glacier draws about 700,000 visitors a year, and once you see the wall of blue ice rising 100 feet from the lake, you’ll understand why.

But the glacier is only part of what’s out here.

Drive right up to Alaska’s most accessible glacier

Mendenhall sits within the Tongass National Forest, fed by the Juneau Icefield, a frozen plateau covering 1,500 square miles.

That icefield feeds 38 major glaciers, and Mendenhall is the only one in Southeast Alaska you can reach by road year-round. The recreation area covers 5,815 acres managed by the U.S. Forest Service.

In summer, cruise ship passengers pour in by the busload. Come early in the morning or late in the evening and you’ll have a lot more room to move.

The Tlingit name tells the whole story

Long before any road ran out here, the Tlingit people called this glacier Aak’wtaaksit, meaning “the Glacier Behind the Little Lake.” They’ve lived in the Juneau area for thousands of years.

Naturalist John Muir visited in the 1880s and named it Auke Glacier after the local Auk Kwaan band of Tlingit.

It was renamed Mendenhall in the 1890s for Thomas Corwin Mendenhall, a scientist who helped define the Alaska-Canada boundary.

Today, the Central Council of the Tlingit and Haida Indian Tribes of Alaska holds a co-stewardship agreement with the U.S. Forest Service for this area, including cultural work inside the visitor center.

A wall of blue ice, 100 feet tall

The glacier runs about 1.5 miles wide where it meets the valley floor, and the face of it rises more than 100 feet. It drops roughly 4,500 feet in elevation on its journey from the icefield down to the lake.

The ice you’re looking at isn’t new. Scientists estimate it took 200 to 250 years to travel from the icefield to the terminus, meaning the ice at the face formed several hundred years ago.

The blue tint comes from how dense, old ice absorbs and reflects light. On a gray day it almost glows.

Nugget Falls drops 377 feet in two tiers

Just east of the glacier, Nugget Falls splits into two drops, a 99-foot upper tier and a 278-foot lower tier, before landing at the edge of Mendenhall Lake.

Nugget Creek carries meltwater down from Nugget Glacier on the mountainside above. Years ago, the falls poured directly onto the glacier’s surface.

Now the glacier has pulled back far enough that the water lands on a wide sandbar at the lake’s edge, and you can walk right to the base and stand in the spray.

In winter, the falls partially freeze into walls of sculpted ice.

The trail to the falls is easy enough for almost anyone

The Nugget Falls Trail runs about two miles round trip on a mostly flat gravel path starting from the visitor center.

Elevation gain is only about 140 feet, so families and people of varied fitness levels handle it without much trouble. Near the end, the gravel gives way to rocks and then a sandy beach at the base of the falls.

A relaxed pace gets you there in about 45 minutes, though most people hang around once they arrive. During summer cruise ship season, expect plenty of company on this trail.

Shorter trails show you a different side of the glacier

If two miles sounds like a lot, you have options. The Photo Point Trail is about a third of a mile round trip, paved and accessible, with a direct view of the glacier across the lake.

The Trail of Time runs half a mile and uses interpretive signs to show how far the glacier has retreated over the decades.

If you want more elevation and bigger views, the East Glacier Trail is a 3.5-mile loop that climbs about 500 feet through forest before opening up above the treeline.

The Moraine Ecology Trail covers the raw ground the glacier has uncovered as it has pulled back.

Watch bears fish for salmon a few feet away

At Steep Creek, a short boardwalk trail near the visitor center, black bears wade into the water and pull out sockeye and coho salmon while visitors watch from just a few feet above.

The salmon run draws bears to the creek from July through September.

U.S. Forest Service rangers are usually on site during peak season to answer questions and keep things safe.

Researchers have noted that female bears with cubs tend to favor this creek, possibly because the crowd of people keeps larger, more aggressive bears away.

Sections of the trail sometimes close during heavy bear activity.

The lake didn’t exist until 1929

Mendenhall Lake wasn’t here a century ago. The glacier’s retreat first exposed the basin around 1929, and the lake has been growing ever since. The water runs turquoise from glacial silt suspended in the melt.

For decades, blue icebergs calved from the glacier’s face and floated in the lake.

But in late 2025, scientists confirmed the glacier is no longer touching the lake at all, which means calving has slowed significantly.

The lake drains through the Mendenhall River, which runs about six miles to the Inside Passage. Below the surface, it supports salmon, Dolly Varden char and cutthroat trout.

The glacier exposed a 2,350-year-old forest

As the ice has melted back, it has uncovered something no one expected: the remains of an ancient forest buried for more than 1,000 years.

Some stumps still stand upright in their original positions, roots down, bark intact. A University of Alaska Southeast geologist dated the oldest exposed stumps at roughly 2,350 years old.

A layer of gravel four to five feet deep had sealed the trees before the glacier advanced over them and locked them in.

They’re spruce and hemlock, the same species that grow in the Tongass rainforest all around you today.

The numbers behind the glacier’s retreat

The glacier has pulled back more than 1.75 miles since 1929 and over 2.5 miles since the 1500s.

NASA satellite data shows it retreated about a mile and thinned by up to 2,000 feet in some places between 1986 and 2024.

The fastest period of loss came between 2007 and 2011, when the glacier shrank roughly a football field in length every year.

Researchers at the University of Alaska Southeast estimate the glacier may no longer be visible from the visitor center by 2050.

What you see now is different from what visitors saw 10 years ago, and different again from what future visitors will see.

The visitor center has been watching since 1962

The U.S. Forest Service opened the visitor center in 1962 on a hilltop overlooking the glacier and lake.

Inside, exhibits walk you through the glacier’s history, the ecosystem around it, and the Tlingit people who have lived in this region for thousands of years.

A 15-minute film explains how the glacier formed and how it continues to change. Rangers staff the center and lead talks during summer.

Spotting scopes in the indoor viewing areas pull the glacier’s crevassed face right up close, which matters more each year as the ice continues its slow retreat.

Plan for any season, but know the quirks

Summer brings long daylight hours that stretch well into the evening, plenty of wildlife, and the salmon run. Winter drops the crowds and partially freezes Nugget Falls into formations worth the cold hike.

The visitor center runs reduced hours in winter but stays open. You can reach the recreation area from downtown Juneau by car or taxi.

A public bus gets you partway, but adds a 1.5-mile walk from the nearest stop.

One thing worth knowing: glacial outburst flooding from a nearby basin has happened in summer months every year since 2011.

Check current conditions with the U.S. Forest Service before you go, especially in July and August.

Visit Mendenhall Glacier Recreation Area in Alaska

You can get current trail conditions, visitor center hours and admission details through the U.S. Forest Service’s official website before you go.

The recreation area sits at 6000 Glacier Highway, Juneau, Alaska, about 12 miles from downtown. Several trails, including the walk to Nugget Falls, are free.

The visitor center and some trails require a pass during summer season.

Summer hours run longer than winter hours, so check ahead if you’re visiting between October and May. Arrive early to beat the cruise ship crowds and get the trails mostly to yourself.
