Well worth the money

This is a really pretty site. The camping and beach access is great. We saw bald eagles and very low flying cargo planes. There is some kind of RC flying area on the north side of the site.

There is road noise, but that is going to depend on where you camp. There are sites right next to the road and sites a few hundred yards away. There are"homeless" camps here. They didn't bother us, but you can tell that not everyone here is a recreational camper.

It is large enough that we got our class A with trailer in and out. There is a bit of a loop, but this can be blocked so check first. The road is very rough, you have to go slow.

There is a dump and non-potable water station at the park a few miles up the road. It is$5 for non-campers today.

pretty great

The lake is lovely! Portos and fire rings. Medium-full on a June weeknight. Minor road noise. A little trash, a little local-party-spot vibe at times, but not bad. Would stay again as a solo female.

Big open area next to lake with Port-o-Potties

Been here many times. Sometimes strange folks show up but they almost always keep to themselves.
Great place to spend some time next to a lake.

14 day limit in 30 days.
