Cracker Lake

Overview

Cracker Lake sits at the head of a steep-walled canyon in the Many Glacier area, a classic glacial cirque framed by peaks like Mount Siyeh, Cracker Peak, and Allen Mountain. What makes it unforgettable is the milky-turquoise water—colored by fine glacial silt—set against towering red and gray cliffs.

The Hike

You’ll start near the south end of the parking area above Many Glacier Hotel and follow an out-and-back trail roughly 12.6–13.2 miles round trip with 1,100–1,900 feet of gain. Most hikers take 6–8 hours. It’s one of the area’s standout day hikes, typically less crowded than Grinnell Glacier or Iceberg Lake if you get an early start. Expect panoramic walls, streams, wildflower meadows, and that jaw-dropping lake color when you crest the basin.

What Makes It Unique

The lake’s vivid turquoise hue comes from rock flour suspended in the water, washed down from glacial sources. The cirque is dramatic—cliffs rise thousands of feet right from the shore. You’ll also find historic mining relics near the lake, a surprising bit of human history in such a wild setting.

Wildlife

This valley is prime grizzly bear country. Encounters are possible, so carry bear spray, hike in groups, and make noise. You might also spot mountain goats, bighorn sheep, marmots, and various birds along the way.

Amenities & Camping

At the far end of the lake there’s a designated backcountry campground (permit required) and a pit toilet. There’s no potable water or food service—plan to filter from streams or the lake and pack everything you need. No picnic tables or other developed facilities.

Conditions to Expect

Winds can whip across the basin, making it chilly even on fair days. Bugs can be pesky in early summer. The first stretch of trail can be muddy and uneven after wet periods. Parking at the shared Many Glacier Hotel area fills early—getting there before 7 a.m. helps.

Best Time to Visit

Late June through mid-September offers the most reliable conditions. Aim for an early start on summer weekdays to beat crowds and secure parking. For photos, early or late-day light brings out the lake’s color and adds texture to the cirque walls. If you’re tempted by a dip, remember the water stays very cold, especially earlier in the season.

Preparation Tips

Check current trail status for snow or wildlife-related closures. Bring layers for wind, a proper map or GPS, plenty of food and water (or a filter), sun protection, and bug spray. If camping, secure a backcountry permit in advance and follow strict food storage protocols.
