A primitive campground at the northern reaches of the Grand Canyon will be available by reservation only starting Sept. 1.
Tuweep Campground lacks services such as water, gas and cellphone coverage. Grand Canyon officials say the change will help visitors ensure they have a place to stay once they make the difficult drive.
Campers can make reservations four months in advance. Walk-up permits may be obtained up to six days in advance in Fredonia or St. George, Utah.
Permits had been required for only the large group campsite. The nine family sites had been available on a first-come, first-served basis.
Visitors also won't be able to build a fire or have a charcoal grill at the campground as of Sept. 1. Gas stoves are OK.
