South Rim, Grand Canyon National Park
The South Rim, in and of itself, is a tourist trap. It is said that the average visitor spends only 8 minutes actually looking at the grand Canyon and that the rest of the time is spent wandering around Grand Canyon Village. There are exhibits and observation points that are worth seeing, but making this the entire Grand Canyon experience would be missing out on the place.
Unique Suggestions: Hike below the Rim, at least a little ways. Take Bright Angel Trail down to Mile and a Half Resthouse, at least, or hike a mile or so down the South Kaibab Trail to get a glimpse of the Canyon. Better yet, leave the South Rim and head up to the North Rim.
Fun Alternatives: Visit the North Rim instead. Or, if you have only one day, take a flighseeing tour over the Grand Canyon. At least you'll get to see it.
The South Rim draws most of the visitors and is open to the public all year round. At this rim you'll find most of the facilities for tourists like the Visitors center, the Tusayan Museum and the Yavapai Point Museum. We als went for a strall to the old Santa Fe Station which was closed in 1968.
The South Rim is also the start of the Bright Angel Trail which is a walk of 16 kilometers into the canyon. Of course walking into The Grand Canyon provides you the best information about how this wonder was established.
Over 4 million people visit Grand Canyon National Park each year. That is not a lot compared to the Sistine Chapel (which I visited on an off-day; only 10000 others that day), but the crowds can still be a bit mindnumbing. You have to have patience and keep a cool head - for others around you will not do either. If you want to stay in one of the lodges here, plan far ahead and get reservations. The same should be said for campsites - one week maximum. On the South Rim, you overnight either around the Grand Canyon Village or at Desert View.
Unique Suggestions: Trails and viewpoints abound away from The Village.
Fun Alternatives: CONSIDER: Staying out of the Park at night and on trails and viewpoints away from the Village during the day. Also, give serious thought to wether you really want to visit in the summertime. It is very hot and very crowded. Winters, on the other hand, can be quite cold - it is 7000 feet here on the South Rim.
Also, think about the North Rim. More super views with fewer people, but remember that it is a 5 hour drive between the two Rims.
