A map of the Crystal Lakes Trail from Mather Memorial Highway. Use of a topographic map of the area is recommended.
Hiking time, round-trip:
Lower Crystal Lake
Upper Crystal Lake
The trailhead is located on SR 410 approximately 4 miles north of Cayuse Pass toward the north park boundary. It is on the east side of the road near Crystal Creek.
The first 1.5 miles of trail climbs through the forest on a series of switchbacks which provide a good look at Mount Rainier until the view is eclipsed by Crystal Peak. The next mile leads to forested Lower Crystal Lake, the smaller of the two lakes. The lovely open basin containing Upper Crystal Lake lies .5 mile beyond the lower lake.
Along the Trail:
By late July and early August the meadows explode with a wide variety of colorful subalpine wildflowers. Watch for elk and mountain goats grazing on the surrounding slopes and ridges anytime throughout the summer and early fall. A side trip to Crystal Peak (five miles round-trip) is well worth the effort. On a clear day five volcanoes can be seen from this 6615 ft. former fire lookout site. Start early in the day if you plan on hiking to the peak as the trail traverses a shadeless south-facing slope which can be very hot and dry during summer.
There are wilderness camps both at Lower and Upper Crystal Lakes. Be sure to camp in designated sites only. Permits are required for camping. Permits and current trail conditions are available park-wide from Wilderness Information Centers, Ranger Stations, Visitor Centers and on our web site. Fires are prohibited. No pets on trails.
