Blue lake is really pretty but the 15 extra minutes of hiking takes you to horseshoe lake. Definitely go the extra 15 minutes. The little jetty is a great place to camp. You have 270 degrees of water views around you, fish jumping, and a bald eagle that stuck around for the 2 days I was there. Would recommend it. I even went with a group where they took 2 babies and a 2 and 3 year old!
