Antelope canyon is a slot canyon located in Page, Arizona. I visited this place this summer. It was carved out of water and wind. It is an amazing nature's creation. The views inside are breath taking.
The snapshot below is the entrance of the canyon
The following two shots are the ones taken inside. We reached this place around 3-4 p.m. The best time to photograph this site is in the noon, when the vertical rays of the sun vividly lit the canyon.
