Seriously beautiful! We were in a tent, and I would recommend a trailer/camper if you have a waterfront spot like this one, as it gets very windy on this side of the lake in the afternoons, and extremely cold at night, even in the middle of summer.

This place has everything you could need. It's a 5 minute drive to the visitors center at majestic Crater Lake. Want to hike up to a mountain peak? The trailheads to both Mt Thielsen and Mt Bailey begin here. There is an 11-mile loop around Diamond Lake perfect for hiking or biking. The campground has a lodge/resort with a restaurant and a (lake) swimming area, water sports and amusements, and boats etc to rent for fun on the water. They also have a restaurant/store/laundromat at the other end of the campground. The only thing I'd add is a few small playgrounds scattered around.

Definitely a destination campground, not one to just pass through.
