Although it lies only ten air miles across the canyon, the North Rim is more than 200 miles (320 km) from the South Rim by vehicle or a strenuous 21-mile (34 km), two- to three-day cross-canyon hike. The North Rim sits considerably higher than the South Rim—8200 feet (2500 m) at the edge of the canyon, almost 9000 feet (2700 m) at the entrance station. The road into the North Rim opens in mid-May and remains open until the first heavy snowfall in November. Most facilities are open mid-May to mid-October.
Summer temperatures are pleasant along the rim, but increase rapidly as you descend into the canyon. Low humidity causes significant temperature differences between day and night. The low humidity and high elevation also means that it is important to drink water frequently. Afternoon thundershowers are common in July, August, and early September. Windy conditions prevail in April and May. Snow may fall as early as November. Winter snowstorms continue into March. Roads are plowed frequently, so closures seldom last long.

Four shuttle bus routes serve many areas of the South Rim—two operate year-round and two seasonally.
