Lower antelope canyon is a slot canyon with a V shape, as opposed to upper canyon's A shape. We visited lower antelope canyon during mid-morning on 12/31 with wife and kids (7 and 8). No matter whether you are a hiker, explorer or not, this is a world wonder one must visit at least once in a life time (think Giza pyramids, Machu Picchu, Niagara Falls or the like, but millions of years older). The mix of shapes, textures, colors, smell and touch makes this place like being inside a dream.
