EXTREMELY NARROW! there is only room for your body, and YOU MUST BE SURE IT IS NOT GOING TO RAIN. when you enter to the canyon, you must keep going in one direction until the end, it is an hour and a haft to go all the way to the end. Never enter if you think it may rain, the canyon is flooded in a couples minutes, if you are in when is raining... there is no way to get out. Sorry! but that is the truth.
