Family Friendly When taken as an overnight, the one way distance is trimmed to just over 6 miles, which makes this a great first backpacking or overnight camping experience .


From the cerulean blue waters of Cracker Lake to the absolutely massive rock face of Siyeh Peak the hike into Cracker Lake is worth the work it takes to visit. The only drawback is the popularity of the route to horses which tend to leave a fair amount of dung along the trail that hikers must avoid.


Start in the Many Glacier area of the Park and begin the relatively easy hike about six miles into the Glacier backcountry. This is an excellent distance for an overnighter and the camping at the head of the basin is sublime.

Follow Allen Creek up the gorgeous, glacial mountain valley under the peaks of Allen and Wynn Mountains. Here, you'll enjoy the sight of snow on the high peaks well into the late summer months, and see the cascading waterfalls from the high cliffs as that snow melts.

Upon reaching your destination at the head of the basin, you are treated to the north face of Siyeh Peak. This is considered by some to be the tallest vertical rock face on the continent - including the imposing faces of California's Yosemite.

The intrepid alpine lake swimmer may choose to brave the frigid waters of Cracker Lake. Don't be fooled by its deep blue tropical-looking color - it is extremely cold!
