Zebra Slot Canyon
if you show up in Sept/Oct, you have to swim to gain access to this canyon. By showing up in the Spring time, I just walked in.
You need to do chimney in a couple of places. I had the place to myself for a couple of hours until 11am when four different groups show up at the same time. I had to get out; there is no room for all the people. One guy had a huge backpack. I told him to leave it outside. He did not listen to me. The slot canyon was too narrow.
