Trillium Lake is easier and faster to get to than many of the other Mt. Hood Lakes, and with one of the best views of the mountain. It's a smaller area, and the day use area get pretty busy, so it's nice to have a campsite to get away from what can be pretty large crowds. Good lake for beginner kayakers as it is small, still, and doesn't allow motor traffic. There is also snow-shoeing here in the winter, but don't underestimate the sloped road you have to get down (and back-up) to get to the lake in the first place!
