They don’t call it the Dirty Devil for nothing. It is a turbid flow, thick as a coffee milkshake, and shallow sandbars lurk below the impenetrable current to snag your boat. We took a couple of inflatable canoes and kayaks. The first day and a half we picked our way through sandbars, often getting out to wade to deeper channels, stopping to explore side canyons, being pulled under sandstone rims. After that we hardly had to get out again.
Take warm gear, because March snow squalls are entirely possible. You can manage it in four days, but if you have a week, it’s nice to dawdle and explore. Tributaries like Happy Canyon are amazing side hikes, worth a layover day. At the end, blast down the final 15 miles, because you enter the zone of old bottom deposits from Lake Powell and camping gets scarce.
