Candlestick campground is gorgeous. The views are breathtaking. The road to access this site is the white rim trail. You will need a permit from the island in the sky visitor center and a camping permit from there or rec.gov. The road is rough, and has some technical aspects to it, so high clearance 4x4 and experiences off road driving is a must. Access to mountain bikers and hikers is available as well. Keep in mind we did this in January. We saw no one else on the trail, or campground but when peak season hits you need to get permits and camping reservations months in advance or win the permit lottery.
