My family stayed at Riley Creek in July of 2015 for 2 days and loved it so much that we decided to stay for 7 nights this summer. There is a moderate amount of traffic with camper trailers and vehicles coming and going, but it isn't unbearable. The sites are nicely maintained with nice, edged out tent pad areas. The surrounding trees provide a nice barrier between sites so you don't feel crammed into the campground. It is a great place to be for easy driving, walking, and free shuttle access to all that the park has to offer. It is a great place to stay, just make sure you make online reservations to guarantee a spot!
