Brainard Lake is a beautiful alpine lake in the Indian Peaks Wilderness below the Continental Divide surrounded by subalpine forest. It is in the Brainard Lake Recreation Area, which during the summer season usually requires a reservation and a fee, but if you are on your bike you do not need to pay or reserve a time slot. Because of the area's high elevation, snow typically remains until late spring, even on the paved road to the lake.
