Natural Features

The cabin sits near the shores of Crystal Lake. The beautiful lake spans 45 acres at an elevation of 5,700 feet. With a maximum depth of 15 feet, the lake seeps fresh water through a porous limestone bottom. The lake generally freezes in the winter.

The Big Snowy Mountains, lush with mixed conifers, rise up from the lake, providing spectacular views. The highest peaks in the mountain range reach 8,600 feet.

Nearby Attractions

Crystal Lake, Ice Caves


The Ice Caves Trail leads hikers to the ridgetop of the Big Snowy Mountains, where it intersects with the Crystal Cascades Trail Bypass. The Lake Loop Trail trailhead, located at the north end of the Crystal Lake Campground, takes hikers to Grand View Trail Junction and additional ridgetop views. Both the Ice Caves Trail and Grand View Trail may be impacted by winter snow as late as the first part of July.

The lake freezes over and ice fishing is possible if the ice is thin enough for fish to survive. In summer months, the lake is stocked with rainbow trout. Kayaking and canoeing is popular.
