Awesome Campground for Lava Viewing
This is a really neat place to camp. It's situated on the east side of Clear Lake, which formed when a lava flow dammed the McKenzie River. The campground is actually built on the lava flow, so it's really cool for checking out rocks. The campground is right off a highway, so it's easily accessible, but isn't near the road so traffic noise isn't bad. The campground itself is pretty large and popular on the weekends, so reserve a spot early or avoid it if you don't like crowds. There is a decent amount of space and vegetation between sites, so you don't feel too crowded.
