Riley Creek Campground is a fairly wooded campground, with some screening between sites whenever possible. Most of the campground sites are open to either tent campers or vehicles / RVs. The proximity of Highway 3 means there is occasional traffic noise, but also means campers have all the conveniences and amenities of the park entrance area, and businesses outside the park, close at hand. Trails leading from the campground connect to the Denali Visitor Center, which is the central hub of trails in the entrance area.
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!
The park is beautiful and I feel privileged to have stayed at a campground surrounded and close to such beauty. The campground was pretty standard. Sites had little privacy and the campground was pretty busy, but being close to such amazing hiking is worth the small negatives. Facilities were clean and well maintained. This is a place we want to return!
