Edith Lake is a small, but stunning, alpine lake perched high up in a bowl. Sitting at 8,660 feet above sea level, this lake often remains frozen into early summer. This is a great place to take photos and relax by the water before heading up the challenging Sand Mountain Pass or returning to the trailhead.

Sand Mountain Pass is a challenging, but rewarding section of hiking deep in the Sawtooth Mountains. As you ascend dozens of switchbacks you are granted fantastic panoramic views over the jagged peaks and blue alpine lakes. At the top of the pass there is a spur trail to the east, which takes you up to the summit of Sand Mountain.

The Twin Lakes are just a short hike from Alice Lake and El Capitan. Both are glacial lakes that are separated by a narrow strip of land and nestled nicely between the rugged peaks of Snowyside Peak and Perfect Peak.

Alice Lake with impressive El Capitan towering just next to it is a popular hiking and multi-day backpacking destination. And for good reason, as the alpine scenery is absolutely perfect.
