  • Distance: 5 miles round trip
  • Elevation gain: 700 feet
  • Trail type: Out and Back, Moderate

Hike past waterfalls, along streambeds, and above a glacially carved gorge. This hike ends at a crystal clear alpine lake named after a founder of the national park, Enos Mills. The trail is well marked and well used. Once at Mills Lake, you have the option of continuing up an additional 1.7 strenuous miles to Black Lake.

Note: The Glacier Gorge parking lot is very limited and fills very early in the morning. The park’s free shuttle is here to help! Park at the Park & Ride and take the shuttle to stunning destinations and popular trailheads, all while avoiding the hassle of dealing with traffic and searching for parking.

Weather Warning: Weather in the mountains can turn in an instant! Be prepared for changing weather conditions. Check the forecast before heading out. Lightning can strike anywhere in Rocky. Watch for building storm clouds and return to the trailhead immediately if you hear thunder. As a rule of thumb, try to be back at the trailhead by noon.
