This is an awesome spot with all sorts of beautiful views of the lake and some absolutely wonderful exhibits inside the small building.
They have some great exhibits in there which talk about Mount Mazama and exactly how Crater Lake from it. It's quite educational, and if you have kids with you this is a great place to bring them!!
There are some great, unique views from the observation deck as well. You go down some stairs from the room to get to this place, so you have a slightly lower review than you would normally get which is kind of cool and unique. Good views of Phantom Ship, Wizard Island and some of the other formations in the distance.
This spot is one of my favorite spots in Rim Village, and I try to stop in every time I'm here and it's open.
