Practical Info
Suggested Duration5-7 hours
Best TimeDue to high-alpine snowpacks pack blocking the upper corries, this legendary 9.7-mile wilderness trek is viable only from mid-July through early September. Setting out by 7:30 AM is ideal; hike through the alpine valleys of the Many Glacier region before arriving at the lake by 11:30 AM, when the high overhead sun beautifully catches colossal teal icebergs floating directly out of the emerald-colored glacial waters.
Getting ThereTucked inside the isolated northeastern Many Glacier valley, detached from the main highway corridor. Drivers take US-89 to the border outpost of Babb, turn west onto the unpaved spans of Many Glacier Road, and ride it for 12 miles to the Swiftcurrent Motor Inn parking lot. As this backcountry valley is a premier grizzly bear habitat, carrying active bear spray is strictly mandated; no mass transit runs here.
Travel Tips
- The 4.8-mile one-way alpine hike passes through steep, semi-enclosed scree basins heavily frequented by grizzlies; solo hiking without accessible bear spray is highly dangerous.
- Shaded by the massive walls of Mt. Wilbur, the lake basin stays chilled; large ice floes linger even into August, making open swimming an immediate risk for hypothermia.
- The trailhead begins behind Swiftcurrent Motor Inn in Many Glacier; unticketed vehicles must clear the Many Glacier park entrance checkpoint before 06:00 to avoid being turned back.
Reviews
Positive
- A top-tier hiking route that truly lives up to its fame! The trail ends at a glacial lake beneath 3,000-foot sheer amphitheater cliffs, with massive icebergs floating in August.
- The 4.8-mile one-way trail is scientifically planned with a gentle, steady elevation gain; it traverses thick woods, alpine meadows, and waterfalls with well-kept gravel tracks.
- A pristine wildlife paradise for spotting black bears, grizzlies, and bighorn sheep; the park service deploys rangers to patrol the trail and offer real-time safety guidance.
- No extra trail fee required, returning immense value. Sitting on rocks at the lake listening to icebergs cracking in emerald water offers a pure, quiet vibe you'll never forget.
Heads up
- The round-trip spans nearly 10 miles (16 km), demanding high physical stamina and endurance; it takes 4-6 hours and is completely unfeasible for untrained guests or toddlers.
- The trailhead sits in the hyper-popular Many Glacier core area where public parking is severely inadequate; drivers arriving after 8 AM face a total absence of open spaces.
- Being a core grizzly bear habitat, trail closures are triggered frequently when bears forage nearby; weather and wildlife unpredictability mean you might drive far only to face a closed sign.
- The miles of mountain trail feature zero restrooms or trash cans (only pit toilets at the trailhead lot) and lack multilingual signs, requiring international guests to pack out all waste.
