Definitely in the middle of nowhere... we got lost about three times! But a beautiful campground. It is smallish, but the view of the water is great! No showers or water though.

It took a little patience to get there. The site is not as big as you might think. When we rounded the corner, it was an "aahhh" moment. Close Encounters of the Third Kind immediately swarm you brain and memories.

The are is well maintained, we were pulling a trailer and did not have any problem finding parking. Dogs can get out but are not allowed on the trail so you will have to give them their break in the parking lot area.

The Forest Service Rangers were very nice and not pushy about selling any merchandise you may want. You can walk around the base, it's a quick and fairly easy walk up a well maintained trail.

Since I am a child of the 80's, it was awesome. For my 14 year old son, he was like, "yeah mom, cool..I'm hungry where can we eat?" There are tables to eat at but food is not sold.
