A few miles past Wolcott is the Castle Peak Wilderness Study Area which holds quite a few little known idyllic camping spots. Blue Lake is by far one of the most serene glacial lakes in the area and offers multiple primitive camp sites designated by fire rings. The lake is accessible by hiking trails and by 4x4 roads, if driving I would highly recommend a high clearance vehicle as many of the ruts on the road are very deep. I have camped here many times, in the summer you are likely to be sharing the lake with another group or two but it is never crowded. I have spent a few weekends here throughout the fall and had the place all to myself. The water is crystal clear and lovely for a dip (if you can handle the cold!). A few kind souls have even left their row boats in the woods next to the lake, to my knowledge they still leave these here for others to enjoy, just please remember to put the boats and paddles back where you find them! There are also quite a few nice hiking trails around the area which are well marked with signs.
