Introduction:
If you’re looking for a hike that combines a bit of challenge with some of the most stunning scenery in Utah, Lake Blanche in the Twin Peaks Wilderness is your go to destination. This gem, located near Mounthaven, Utah, takes you through a journey of breathtaking landscapes that culminates at a serene alpine lake surrounded by rugged, towering peaks. Whether you’re an experienced hiker or just someone who loves the outdoors, Lake Blanche promises an unforgettable experience.
How to Get There:
Getting to Lake Blanche is straightforward. Start your journey from Salt Lake City, which is about 20 miles away. Take I-215 to Exit 6 for 6200 S/3000 E, and then follow Wasatch Boulevard south. You’ll soon turn left onto Big Cottonwood Canyon Road (UT-190), which leads you through the beautiful canyon. After about 4.4 miles, you’ll arrive at the Mill B South Fork Trailhead, where your adventure begins.
Parking Information:
Parking at the Mill B South Fork Trailhead can be a bit tricky, especially if you arrive later in the day. The lot tends to fill up quickly, particularly on weekends. It’s a good idea to arrive early, perhaps just after sunrise, to snag a spot. If the lot is full, don’t worry! You can park along Big Cottonwood Canyon Road, but be prepared for a short walk back to the trailhead.

Trail Description and Landscape:
The Lake Blanche trail is a moderately strenuous hike, perfect for those who enjoy a bit of a challenge. The trail spans about 6.8 miles round trip and involves an elevation gain of 2,680 feet. As you ascend, you’ll pass through lush forests and exposed rocky areas, offering stunning views of the canyon below. The closer you get to the lake, the more rugged and alpine the landscape becomes, with Sundial Peak standing tall as a dramatic backdrop.
When you finally reach Lake Blanche, you’ll be greeted by a pristine, mirror-like alpine lake. The reflection of the surrounding peaks in the water is truly mesmerizing, it’s the perfect spot to rest, take photos, and soak in the beauty of nature.
Trail Difficulty and Length:
The Lake Blanche trail is best suited for those with some hiking experience, given its steep incline and length. The trail is approximately 7 miles round trip, with a considerable elevation gain of 2,800 feet. It’s not the easiest hike, but the reward at the end makes every step worthwhile.
Is It Dog-Friendly?
As much as we love our furry friends, Lake Blanche is not a dog-friendly trail. The Twin Peaks Wilderness area is part of a protected watershed, and regulations prohibit pets to ensure the water quality is maintained. If you’re planning to hike with a dog, you’ll need to choose a different trail in the region.

Local Regulations:
The Twin Peaks Wilderness is a special place, and there are a few important rules to follow to keep it that way. Since it’s within a protected watershed, no dogs or pets are allowed. Make sure to stay on the trail to protect the fragile environment, and always pack out what you pack in. Practicing Leave No Trace principles is crucial here. Let’s keep this beautiful area pristine for future generations.
