Length: 6 miles out and back
Description: Lake Blanche is a very photogenic landmark in the Twin Peaks Wilderness Area. The trailhead is in Big Cottonwood Canyon, at the bottom of the prominent S-curve.
Impressive Sundial Peak rises above the lake. Two other small lakes (Florence and Lillian) are found in the area and can be visited by hiking short, signed spur trails.
Mill B Trailhead
Several trails begin at the Mill B Trailhead, which is about 4.4 miles up Big Cottonwood Canyon. The Lake Blanche trail is signed and easy to find. Look for it on the east end of the lower parking lot.
Follow the signed trail east from the trailhead. It soon crosses a bridge over a stream and then continues up the mountainside. It is a wide, well-marked trail that leads right to the lake. After spending time enjoying the lake, return the way you came in.
We recommend you hike directly to Lake Blanch. Then, if you have enough time and energy, we strongly encourage you to take the short spur trails to explore lakes Florence and Lillian.
Lake Blanch is the highest of the three lakes. As you hike, watch for paths leading around the other lakes.
Sundial Peak towers over the lakes, and makes a very impressive background for photographs.
