About This Route
Stand-up paddleboarding on the Merced River from Stoneman Bridge to Sentinel Beach offers a 3-mile scenic float through Yosemite Valley, with iconic views of Half Dome, Yosemite Falls, and El Capitan. Launch near Curry Village at Stoneman Bridge, a concrete span popular for its easy access and gentle entry into the river. Paddle downstream past sandy beaches and granite boulders, taking out at Sentinel Beach picnic area. This route suits beginners in low water but requires intermediate skills during peak flows. Water from snowmelt is cold, typically 45-55°F, and the river meanders with mild riffles. Follow Leave No Trace principles: pack out all trash, avoid trampling vegetation along shores, and camp only in designated sites like Upper Pines if overnighting. Check USGS gage at Pohono Bridge for real-time levels; ideal paddling occurs at 2-4 feet.
Safety Considerations
Yosemite National Park mandates US Coast Guard-approved PFDs worn by all when Pohono Bridge gage exceeds 4 feet at 8 a.m.; keep them on possession otherwise, but REI experts strongly recommend wearing them always to prevent drowning, the leading paddling fatality cause per NPS data. Use a quick-release coil leash, never ankle style, to avoid foot entrapment in currents or strainers. Scout for hazards like undercut rocks near El Capitan Meadow; sudden water rises from afternoon thunderstorms can occur June-August. Hypothermia risk is high; neoprene booties and wet suits are essential. No alcohol or drugs, per NPS boating rules. File a float plan with rangers at Valley Visitor Center. Crowds peak mid-summer; launch early to avoid congestion.
Essential Gear
Pack a stable inflatable SUP board like the Red Paddle Co 10'6" Voyager; adjustable paddle from Bending Branches; USCG Type III PFD; quick-release leash; river fin for tracking; 3mm neoprene booties or booties with wool socks; dry bag with first aid, whistle, headlamp, snacks, water purifier; repair kit with pump and patches; sunscreen, hat, polarized sunglasses with leash.
Emergency Tips
If you fall in, float feet first downstream, backstroking to steer from rocks. Signal rescuers with three whistle blasts or high-visibility paddle waves. Self-rescue by swimming board to eddy, remount from knees. For group separation, paddle to shore and hike out via Valley Loop Trail to Curry Village. Call 911 or use park satellite phone relay; nearest SAR from Yosemite Valley base.
