Overview

The Crystal Lake Group Campground is located in the beautiful Big Snowies south of Lewistown, Montana, at 5,700 feet. Home to the Crystal Lake recreation area, visitors enjoy hiking and fishing in the Snowies.

Recreation

The lake provides opportunities for swimming, fishing and canoeing. The various trails that stem from the Crystal Lake complex provide excellent views and interesting photo opportunities. One trail displays old hieroglyphs in a cave allowing visitors a glimpse of the past.

Facilities

Water is available via a spring faucet and is just down from the camping site. An outhouse is provided next to the parking area for the group site. There is room for parking behind the gate in a parking area or to have two (up to 35’) campers parked there as well. Asphalt walkways and tent pads are present but room in the adjacent meadow can be used for bigger tents. Two large picnic tables are on site and a metal fire ring.

Natural Features

Settled in the basin of Crystal Lake, the group site offers great access to trails and ta short drive or walk to the lake. Some trees are around the campsite but may not offer much shade.

Nearby Attractions

Ice Caves Trail, Cascade Trails and the lake are all located in the complex.
