CO: Ice Lake Basin in San Juan National Forest | Possibly the prettiest hike I have been on in Colorado. This trail has everything! Waterfalls, mountain streams, glacier lakes, beautiful views, and tons of wildflowers. Went in mid-July and the trail was in great condition (no snow/mud etc.). If you can get on the trail by 8am or earlier you are guaranteed to have a wonderful day with little chance of afternoon showers.
