You may check in for all of these campgrounds at the Riley Creek Mercantile or the Denali Bus Depot. Check in / check out at all campgrounds is 11 am. People may camp with RVs and other vehicles at Riley Creek, Savage River or Teklanika River; the other three campgrounds are open only to tent-campers, and are accessible by bus. No campground in Denali can accommodate an RV over 40' long - if you have an RV larger than this, you will want to look outside of the park for a campground big enough to accommodate your rig.
