Cracker Lake Trail

Overview

Cracker Lake is a big-day payoff hike: a long, steady climb to a milky teal-blue alpine lake tucked beneath dramatic walls and the remnant ice above. Expect roughly 12.5–12.8 miles total (out-and-back) with about 1,100–1,600 feet of gain. Most hikers take 5–7 hours. The grade is forgiving for the distance, but the length makes it feel moderately strenuous.

Route Highlights

Start from the Piegan Pass/Cracker Lake trailhead at the Many Glacier Hotel parking area. The first 1.5–2 miles share corridor with the horse trail—often muddy with churned tread and manure if it’s been wet. Stay right at the horse-loop junctions to remain on the main trail. After the second junction, the climb begins in earnest via switchbacks toward meadows and a high basin. Along the way you’ll pass brushy stretches, wildflower-filled openings, and several small creek crossings on logs/footbridges. Many people pause at the first overlook, but continuing down to the shoreline (roughly an extra mile round-trip) delivers that “turquoise-at-your-feet” view—and a frigid dip if you’re brave. It’s often breezy at the lake.

What Makes It Special

The lake’s vivid color comes from fine glacial silt washing down from above, giving it that striking milky-turquoise hue that pops against the cirque walls. The approach mixes forest, meadows, red rock, and big alpine scenery—less nonstop drama than some nearby classics, but the finale is among the most memorable in the park.

Logistics and Facilities

Parking is in the same lot used by Many Glacier Hotel, so it fills early—arrive before 7 a.m. if you can. Cell service is unreliable; download an offline map and bring plenty of water and calories. A designated wilderness campground sits by the lake with a pit toilet (permit required). Note that fishing is not allowed at Cracker Lake, and dogs are not permitted on this trail. In summer, a vehicle reservation system may be in effect for the area; policies change, so check current park guidance before you go.

Conditions, Season, and Timing

Snow can linger into early summer, and early miles may be muddy. Buggy, brushy stretches are possible after rains, especially near the horse sections. The most reliable window is July through early September. Start early for easier parking, cooler temps, and a quieter trail; the length helps spread people out later in the day.

Wildlife and Safety

This is prime bear country with regular grizzly activity and occasional moose sightings near the trail corridor. Hike in a group if possible, make noise, carry bear spray and know how to use it, and give all wildlife plenty of space. Yield to stock, step off on the downhill side of the trail, and wait for riders’ directions at passing. Expect small creek crossings and watch footing on muddy or slick sections.

Is It Right for You?

If you want a long day with a jaw-dropping lake as your reward, this is it. If you prefer constant big views from the get-go, hikers often find nearby Many Glacier staples like Grinnell Glacier or Iceberg Lake feel more open en route—Cracker’s drama is concentrated at the end.
