I love the Cascade lakes. Growing up here in Bend we spent a week at the volunteer fireman's cabin on the north shore of Elk Lake every year. I was still living in California the year that infestation occurred but the trees are pretty evident of that still. Glad that Sunset View beach is accessible by road again - it's always a little quieter there than the area by the marina/main lodge.
Devil's Lake has beautiful water (emerald colored) albeit kind of small. Good for day trips for sure! I'm getting into Stand Up Paddle boarding - it's a great way to explore the lakes and get a core workout in at the same time!
