We actually were staying at Bridge View just up the road closer to Grants Pass, which was a great place to stay. While doing a bicycle ride on the paved river trail we came upon this site and loved it. Lots of trees and big spaces in between RV spots. The bike trail goes through this area and will take you to the town of Rogue River City. Great trail. The freeway is close by so you may want to get a spot closest to the River. But less freeway noise then Bridge View. So lots of trees and a great feel with lots of big space in between parking spaces. Not a parking lot feel at all? Oh, full hooks ups at many sites, but some areas have just electricity or no hooks ups at all.
The camping in loop B was crowded, no privacy, sparse tree coverage. The Rangers have Jr Ranger events for the kids, but the place is strangely devoid of character. It's okay if you're passing through, but certainly not a destination, Also, very hot in the summer, so make sure your A/C is up to snuff.
We visited in the early spring. Not much rain but very cold. The park was clean and it looked like after winter maintenance was just underway. The camping is pretty close to I-5, so expect some road noise. Overall a decent spot, but not a "have to" destination.
