Hidden south of Amarillo is this lovely canyon that few know about!  It is second in size only to the Grand Canyon and is very unlike the plains above it. Nice campsites, shower/toilet facilities a bit old and buggy as Hackberry is an older part of the park.  Wolfberry and Juniper campgrounds in the park have newer, beautiful facilities. Sites are a nice size and there are a lot of trees between them.  Lots to see and do if you're into nature and hiking and bird watching.  Also saw wild turkey and a yellow snake. Rock formations and cliffs are awesome.  June was very hot.
