Horseshoe Mesa is a wild part of the Canyon. Grandview
is the highest point along the South Rim. Allow yourself
plenty of time, and don't go in August like I did.
My first canyon hike. Went to Horseshoe Mesa on a trail that is much more rugged and fun than the well travelled route of Bright Angel. At the cave a spelunker brought us through a few openings but I was quickly intimidated by the swiss cheese interior. Don't go in lightly.
