That whole area is beyond beautiful. Before I had a child, lol... was there MANY times thru the Spring/Summer/Fall, every year. For various reasons! Just be aware that the lake differs in depth BIG TIME. Usually it's August-ish when it's VERY low. I was surprised to see a trinkle of water running where I had cliff jumped a couple months before, LOL!
Maybe I'll try to go there next month!
