Overview
Red Pine Lake is the premier alpine lake hike in Little Cottonwood Canyon, offering comparable scenery to the more famous Lake Blanche Trail in Big Cottonwood Canyon with slightly less total elevation gain. The 6.6-mile out-and-back climbs 1,900 feet to a glacial lake at 9,646 feet beneath the dramatic white granite face of White Baldy (11,321 feet). The Wasatch National Forest and its portion of the Wasatch Range provide this remarkably accessible alpine experience just 25 miles from downtown Salt Lake City.
The trail shares its lower mile with the White Pine Lake Trail before diverging right toward Red Pine. Both lakes are worthy destinations; Red Pine is slightly lower and larger, White Pine sits in a more austere cirque higher up. Most hikers pick one; strong hikers sometimes do both in a single long day.
Watershed rules: Little Cottonwood Canyon is a protected drinking water watershed. No dogs. No swimming. No body contact with water sources.
The Route
Miles 0 to 1: Lower trail. The trail starts in a cottonwood grove and climbs steadily through mixed forest. The White Pine junction comes at about mile 1; stay right for Red Pine.
Miles 1 to 2.5: Mid-trail switchbacks. The grade steepens as the trail climbs through open terrain with views back down the canyon. The granite walls of the Wasatch become more prominent.
Miles 2.5 to 3.3: Lake basin. The trail levels as it enters the Red Pine Lake cirque. The lake reflects White Baldy on calm mornings. An upper bench holds a smaller seasonal tarn.
When to Visit
Late June through October. The canyon gets heavy weekend traffic in July and August; arrive before 8 AM for parking. Fall is quieter and the aspen groves turn gold in late September.
Practical Details
Fee parking at the trailhead (as of 2026). Flush toilet facilities at the lot. The Alta Ski Area and the town of Alta are nearby. For related Wasatch hiking, see the Cecret Lake Trail and the forest guide.
Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
