The Grand Canyon’s South Rim is well developed and open all year (the North Rim is closed in the winter). The two main sections catering to tourists are the Village, which includes accommodations, and the Visitor Center. Between them is the Rim Trail. This is a pedestrian-only walkway providing canyon views. West of the Village is Hermits Rest. East of the Visitor Center is Desert View. The roads leading to both extremes each have at least six major observation points. Shuttle buses and tours are available. Your best bet is to enjoy exploring one direction per day.
