Camping inside the park boundaries is strictly limited to the official campsites at Ásbyrgi and Vesturdalur (plus Dettifoss for hikers only). Vesturdalur's campsite is near the ranger station and has no powered sites, showers or hot water – toilets and running water are the only luxuries here.
Vesturdalur is 14km south of Ásbyrgi off Rte 862. At the time of research, it was 8km from Rte 85 on newly sealed road, a further 4km on gravel to the Vesturdalur turn-off, then 2km to the area.
