There are several campgrounds in the immediate area (near the twin lakes of East Lake and Paulina Lake) and this is one of the most popular both because of the nice beach, but also because it's fairly small (and thus fills up fast).

It's basically one squished oval loop on the lake. Several spots are right up against the beach, others have peek-a-boo views, and they're all within walking distance.

There's a boat ramp as well as bathrooms. No showers.

There's also not a ton of privacy since the trees are fairly thin and all the spots are semi-crammed in, but not too bad considering you'll want to be down by the lake most of the time anyway.
