This is one of our favorite lake views in all of Utah. Though challenging, (the trail is mostly uphill the whole time), the lake and mountain backdrop views are well worth it.
Parking at the trailhead lot is most often full, but you will see parked cars starting to line the sides of the main road. Be prepared for a bit of a walk from your car, as this is a very popular spot. The hike begins along the creek on the paved Mill B South trail, but shortly turns off to the right up a steep dirt path. The trail is a consistent incline, but does have some nice tree-lined areas for a break in the shade. Close to the top, you’ll encounter some larger rocks to scramble around. When you get to the lake, there’s a few spots to explore. If you go straight, to the left of the lake, you can check out the waterfall. Go right, and you’ll find large slabs of rock to picnic/take a snooze on. If you continue curving around the right side of the lake, there are a few more lakes that flow from Blanche (Lake Florence and Lake Lillian) and some campsites. Reminder that all these lakes lie within a protected watershed, so no swimming is permitted! Big Cottonwood also does not allow dogs, so reminder to leave your pups at home.
This is best accessed during the Spring-Summer months. Be prepared with sunscreen and bug spray, as late summer tends to get a bit buggy. Winter hikers: check avalanche conditions beforehand and bring your snowshoes/microspikes/skis.
