If you are visiting the Grand Canyon and have some extra time, I highly suggest stopping by Horseshoe Bend for a bit. It is located approximately 140 miles from both the South Rim and the North Rim so it is a bit of a drive.
Horseshoe Bend is named after the horseshoe-shaped meander of the Colorado River located near the quaint town of Page, Arizona, in the United States.
It is accessible via hiking a 1.5-mile (2.4 km) round trip from U.S. Route 89, but an access road also reaches the geological structure, as it is part of a state park. Horseshoe Bend can be viewed from the steep cliff above.
Horseshoe Bend is also very close to Antelope Canyon so if you are going to one, you might as well go to the other. Take a bottle of water or a power drink as it can get really hot and tiring getting there as most of the trail is on sand.
Make sure to pack a wide angle lens to get some cool shots of the whole bend. Take your time and enjoy the sights. You might even notice some people camping by the river if you are lucky.
