... et visiblement très demandé:
From spring through fall, a campground ranger staffs Camp 4 each day. You must register with the ranger in order to stay at Camp 4. The ranger arrives at the campground kiosk around 8:30 am, although, a line has often formed well before then and the campground may fill before everyone in line is registered. Space is available on a per-person basis and each person wishing to register must be present. Six people will be assigned to each campsite; people in one group may be assigned to different campsites.
