Battleground is a nice and well loved state park not far from Portland, Oregon and Vancouver, Washington. The part itself centers around a clear caldera lake with tent camping, RV camping, cabins, trails, group sites, and the like. The lake is also frequently stocked, and fishing is popular. Not motorized boats, but plenty of kayaks and rafts. There is a small camp store with snacks and fishing supplies on-site. Campground is well appointment with showers, water, etc.

Hiking around the lake is fun. And well a crowded park, it is easy to sneak away to a quiet spot. Some cabins and campsites have nice views overlooking the lake. The town of battleground is nearby with restaurants, grocery stores, and any you might have forgotten.
