I took my three kids up to the lake. The trail was mostly switch backs up until the last half mile or so. At the top there was an awesome meadow with a great lookout over the valley. Finally a steep jaunt down to the lake. The bugs were not too bad however my daughter and I got stung a couple times by hornets on the trail. There was a nice open campsite with a small rocky beach. The lake was clear and cold. We caught a few 10 inch rainbows over two days. We walked to the far side of the lake past the outlet and fishing was better over there. You could see the trout swimming. However our second night it started pouring. We stayed dry but headed out early the next morning. I would grade this hike as moderate due to the steepness but that might be because I had to carry extra gear for my kids.
