Blue lakes is one of the most vibrant colored lakes in Colorado and you can camp right at its shores! This is dispersed/backcountry camping only. Spots can be found right before the lake, look for a clearing and setup. This area can get really busy with day hikers and campers so go early and try for a weekday. We went up there on a weekday and saw about 10 other tents. Camping is free, make sure to pack it out there. 

Great jump off point to hike Mt Sneffles or up to the other lakes. The hike is around 3.2 miles one way but worth every step.
