About This Route
From Phantom Ranch (Mile 87) downstream through Upper Granite Gorge to Elves Chasm (Mile 117), this 30-mile section slams paddlers with relentless Class IV-V rapids amid black Vishnu Schist walls. Iconic drops include Bright Angel (Mile 88, Class 7), Zoroaster (Mile 90), and Grapevine (Mile 108). SUP river running here requires expert skills; NPS restricts to proven veterans via permit interviews. Multi-day camps at Pipe Creek Beach offer respite, but scout every horizon line. Embrace NPS protocols: no alcohol, secure human waste with groovers.
Safety Considerations
Permits demand logged Class V experience; lottery winners face health/history review. Mandatory USCG PFDs prevent drownings, as seen in past fatalities. Granite walls amplify hydraulics; portage Hance Rapid (Mile 77 upstream approach) if fatigued. Heat exhaustion peaks June-August (110°F air); rotate swims, hydrate aggressively. River flows fluctuate 10,000-25,000 cfs; high water hides sieves. Wear NRS Chaos helmets for boulder drops. Follow Leave No Trace: camp 100 feet from water. Train per NRS SUP Rescue Guide: self-rescue flips, high-brace strokes essential. Women note Phantom Ranch resupply lottery; pack 20,000 calories.
Essential Gear
Select expedition SUPs like ISLE Pioneer 3 Plus (14') for stability; add wing walls for tracking. Quick-release leashes, throw bags, and knucklehead knives for entanglements. Kitchen kits with Jetboil stoves; bear-proof Ursacks for rodents. REI-recommended: wetsuits for 50°F swims, camp shoes for scorpion-prone beaches.
