The Grand Canyon is really big, such that it nearly bisects the park. At nearly a mile deep in places, there are no roads across the canyon, necessitating a five-hour drive to get to the North Rim from the South Rim. This often means overcrowding on the south rim. The least crowded times are from November to February, although weather can be an issue at these times.
While the south Rim is open 365 days a year, the North Rim has a shorter season, mid-May to mid-October, due to an almost 1000 foot difference in elevation. Being so far from most towns, the Park is also surprisingly remote, meaning water, gas and other necessities could be in short supply or unavailable in certain areas. Car lock smiths and towing companies are far away, and can result in high prices and long waits.
Like many other parks, The Grand Canyon sees many million of visitors a year, so it is very important that tourists do everything they can to leave the park as pristine as when they arrived. Many ecosystems are very delicate and should be treated with care.
Lodging and Camping opportunities are also numbered, so visitors should take care to reserve hotels and campsites well in advance of their trip. Mule rides and river tours are also limited, and must be contacted many months and sometimes years in advance to secure a spot.
Transportation within the park is orchestrated by a group of busses that pick up and drop off visitors free of charge.
Due to Location and a slight higher elevation than the South Rim, the North Rim has a much short season as well as a much more difficult ease of access. The North Rim averages between 7-9,ooo feet about sea level and stays pretty remote.
With ease of access, the South Rim with its favorable climate is the most desirable sight-seeing location at the park. With that being said, this side of the National Park is much more populated with tourists/ activities.
