Riley Creek CG is the first CG in Denali NP. It is the nearest to the mercantile, which has flushing toilets, running water, showers ($4.50 for token, $0.50 for towel) and laundry. It is close enough to the highway to still have 4G cell phone service too, which was nice because the Park Service has some nice content on their website. The CG is primitive, no hookups. There are "A" sites which are fairly long, and "B" sites which are SHORT. If you choose a "B" site, understand you will not likely be able to keep the TV and PUP in line and not be out in the road. Those spots work well for tent campers, buf if you have a long PUP, and a long TV, you may not have enough room to park side by side and you could be in trouble. The spots may be narrow, but they are VERY deep. The main part of each site was BEHIND, not beside the parking pad. So, if you tend to put up an awning and hang out there, you could have a problem with a "B" site. The CG is NICE!!! It is wooded and mostly level. There are a smattering of flushing bathrooms in Riley Creek, with outdoor slop sinks for dishwashing (no hot water). But most of the bathrooms are vault toilets, but still very clean. It is bear country, so I was a little surprised there were not bear lockers at the site, but you have to keep things in your TV anyway. The check in process can be painfully slow, or just take a second, depending on the line. You reserve a "spot", but not a particular space. So once you check in, you drive around and find a spot that it unmarked and take it, and post your plaque. The park is, of course, spectacular. I won't go in to all the park tips, but do some homework before you come in prime season. All in all, we had a wonderful time at this beautiful campground.
