This site is actually the River Site ATV trails which appears to be where local people with their dirk bikes and ATV ride the trails. It's right by the river off the hwy, trash is everywhere and it looks like a very unsafe area. Which was confirmed as we were turning around in the lot to get the heck out of there, a game warden pulled up to all the trucks parked under the overpass. Definitely looked like a super sketchy area. Also it's full dirt so don't go down there if it's wet.

The recreation area is actually about 45-60 mins east of where this pin is on the map.

We would have taken a picture of the shady location but we were too quick to get the heck out of there.
