Went here this summer on our honeymoon. We did a bunch of hiking along the PNW area, and I think Crater Lake was my favorite hiking day. It just feels kind of otherworldly and serene in a very cool way, and the water is so strikingly blue and beautiful. It's also a little bit off of the beaten path compared to other parks so the people sharing trails with you are mostly interested in being respectful hikers as well. Amazing photo of an amazing place.
