Took the short trail around the lake after doing Harney Peak & Little Devils Tower. The lake is beautiful, clean and love the rock formations. Take a dip if you want. Actually watched a couple get married by the lack. It was a perfect background.

This is hands down the most beautiful lake I have even been to. Absolutely gorgeous. We went on a road trip where we visited many lakes in MN, and though they were nice places to visit, this lake was the most beautiful Ive seen anywhere.
