I've passed this site a few times and have used the day use area. Finally decided to camp and so glad I did. Yes, there are trains running through, but they did not bother me. Adjacent to the RV park is a tent site for hikers on the PCT. I loved seeing and chatting with the hikers.  

There is no privacy between sites, but the scenery is gorgeous. Right on the Columbia River. The sites are level with water and electric and a dump station. A nice Island to walk around on. There was even wifi that worked! I think the first time I've ever been able to utilize Wifi at a campground. I loved this place. Paid $41 for one night.
