Visitors to the canyon converge mostly on the South Rim, and mostly in summer. Grand Canyon Village is here, with a majority of the park's lodging and camping, trailheads, restaurants, stores, and museums, along with a nearby airport and railroad depot. Believe it or not, the average stay in the park is a mere half day or so; this is not advised! You need to spend several days to truly appreciate this marvelous place, but at the very least, give it a full day. Hike down into the canyon, or along the rim, to get away from the crowds and experience nature at its finest.
For me, it was Borealis or bust--or both.More
