We were looking for a short destination that would introduce my 5 and 7 year old boys to the wonderful world of backpacking. Blue Lake was perfect. It is a very short hike to the lake ~1.5 miles-ish. You could even make multiple trips to your car if needed. There are multiple spots to pitch a tent and there is even a vault toilet thing but never had to use it. There were two other groups camping at the same time and you would never know they were there. Lots of huckleberries too!
