Red Pine Lake sits in the Lone Peak Wilderness Area, which boasts of wildflowers in summer and an array of birds to watch throughout the seasons. Red Pine Fork, a drainage on the south side of Little Cottonwood Canyon, contains two high-mountain lakes: Upper and Lower Red Pine Lakes. This trail leads to the lower lake, but you can add on the upper lake as well. Camping is allowed at both lakes as long as you camp 200 feet away from the water’s edge. Campfires are not permitted in this wilderness, so make sure you bring a backpack stove.
Red Pine Dam was built in 1920 and still sits along the west side of the lake. Lake levels vary with runoff, which varies by season, but the area is always an alpine retreat.
The hike to Red Pine Lake begins at White Pine trailhead. The trail descends from the parking area next to the restrooms and follows a paved path down to a footbridge that crosses Little Cottonwood Creek and the official White Pine trailhead. The first 1.0 mile of the trail follows White Pine Canyon through beautiful alpine environs to the White Pine/Red Pine fork, where the trails to White Pine and Red Pine Lakes diverge. Take the trail that cuts behind the trail sign on a singletrack trail. You’ll reach the Red Pine bridge 400 feet past this junction. Cross the bridge and head west over the roots, rocks, and wooden bridges that lead you into Red Pine Canyon.
At 1.4 miles you enter the Lone Peak Wilderness Area. At 1.5 miles the view down Little Cottonwood Canyon opens to the Salt Lake Valley and then quickly, after a few hundred feet, drops back into the trees. This midsection of the trail provides the most challenge as it climbs steadily to the top of Red Pine Canyon.
At 2.7 miles you pass the bridge to Maybird Gulch. A trail sign indicates that you must go straight up the side of the streambed to continue up Red Pine Canyon. This section of the trail makes its way across water running downcanyon; the area is swampy for a short while before the trail becomes a boulder-strewn path at isn’t always defined.
When you reach Lower Red Pine Lake at 3.4 miles, there are plenty of rocks to sit on and enjoy lunch. The dam to the west can be crossed on foot to reach the other side of the lake. If you are planning to camp, remember that all backcountry camps must be set up at least 200 feet from the trail, the lake, and all other water sources. Little Cottonwood Canyon is a watershed area, and no swimming or wading is permitted. No campfires are allowed in this wilderness area.
