Big Four Ice Caves Trail

OutAndBack • 2 mi • 200 ft

The nearly level trail, smooth and well maintained, crosses a series of water-spanning bridges and marsh-spanning planked walkways before arriving at the ice caves in the snowfields at the base of the 4,000-foot north face of Big Four Mountain. Hike to a stopping point beneath the tall, wide cirque headwall, dappled with snow patches and waterfalls. The ice caves are formed when the undersides of avalanche snowbanks melt from the action of water and wind. They vary in size and shape from year to year. They do not open until midsummer and are never safe to enter — ceilings have been known to collapse.

For some how is just recovery from knee surgery, this was not a difficult hike. I will say thought that you have to walk 2 mile to get to the trail head because the road is snowed over. Then the trails have 3 feet of snow...that's really cool. Once you get to the top however, the Ice Cave has been covered by and avalanche...DOH! I really want to go back once all that snow is gone.


Packed snow covered the trail the entire way... Made for slower going that expected, but not at all uncomfortable in 50 degree temps. The destination is well worth the trek, even with two young kids in tow.
