Mount Tallac

Mount Tallac is a mountain peak southwest of Lake Tahoe. The peak lies within the Desolation Wilderness on the Eldorado National Forest and is quite visible from Lake Tahoe. A "cross of snow" is clearly visible on the mountain's face during the winter and spring months. Of the several trails leading to the summit, the Mount Tallac trailhead is the most-frequented. This 5-mile one-way trail has an elevation gain of 3,250 feet. The trail takes hikers past Floating Island Lake and Cathedral Lake on their way to the summit. On the southern side, next to Lilly Lake, is Glen Alpine trailhead. While providing a slightly longer route to the summit, (5.7 miles), this trail brings hikers to Gilmore Lake. At approximately 8,300 feet this lake is only 1,400 feet below Tallac's summit. Tallac is a popular backcountry skiing peak.
