Visitation to the South Rim of the Grand Canyon in 2015 is already up compared to 2014. That means that you should expect long waits at South Rim Entrance Station this 4th of July Weekend according to a news release from the National Park Service. They have some suggestions for ways to avoid some of the crowds and we have a few other suggestions as well.
They recommend that visitors coming from outside the Park (Tusayan, Williams, Flagstaff, or just driving up for the day) park their vehicle in Tusayan and ride the shuttle from there into the Park. Another suggestion for avoiding the long lines at the Entrance Station is to plan to arrive early in the morning.
In addition to their recommendations, we suggest if you are departing from Williams or Flagstaff or if you are coming from Phoenix you may want to take a different route and go through the East Entrance to the South Rim via Cameron, AZ. The East Entrance is generally less busy and also gives you the option of traveling along the Little Colorado River Gorge.
