Paddled upstream and back on the Rio Grande River in Santa Elena Canyon in Big Bend National Park. Had to get out and portage (pretty much just dragging the kayak as we waded in the shallow water, never had to go up on shore) numerous times across shallow spots at gravel bars on the way upstream. We were able to ride the gentle current finding the channel more easily coming back downstream. Beautiful high walls in the canyon. Many times we were on the Mexico side of the river. Spectacular
