For everyone who is interested in visiting The Wave, here is the link for the information: http://www.blm.gov/az/st/en/arolrsma...s/permits.html
There is no need permit to visit Buckskin Gulch for day hike, just sign in and put the fees at the trail head, make sure you check with the visitor center for the day you enter the slot canyon, it is deadly if there is a flash flood.
