About This Route
The Merced River stretch from Clark's Bridge (near North Pines Campground) to Stoneman Bridge in Yosemite Valley delivers Class I-II rapids for novice paddlers. This 3-mile float offers views of Yosemite Falls, Half Dome, and El Capitan. Open only when Pohono Bridge gage height is below 4.5 feet at 8 a.m.; check NPS river conditions daily. Launch downstream from Clark's Bridge; no trailers allowed. Expect 1-2 hours with easy portages. Wilderness ethics apply: no dragging boats over vegetation.
Safety Considerations
PFDs mandatory when gage exceeds 4 feet or for kids under 13; NPS strongly urges wearing them always. Strainers from fallen trees and swift currents (3-5 mph) can trap boats; scout rapids. Summer water 50-65°F risks cold water shock. Watch for poison oak along banks and rattlesnakes in sunny spots. High tourist traffic means crowded put-ins; arrive early. Follow NPS boating regs: vessels in good condition, designated launches only. UV exposure intensifies; apply SPF 50+ reapplied hourly.
Essential Gear
Opt for a stable recreational kayak like Dagger Stratos. Equip with Stohlquist Trekker PFD, Carlisle paddle, and helmet for Class II. Carry drysuit or wetsuit (Kokatat), repair kit, and map of river gages. REI suggests paddle float for self-rescue and bivy sack for unexpected bivouacs. Include bear spray and food in waterproof Orsack.
Emergency Tips
Pin risks high; use upstream V-furrows to avoid. If flipped, float feet-first to eddies. Yell for valley shuttles or rangers patrolling Valley Loop Road. Limited cell; head to Stoneman Meadow for signal. Evacuate pins with throw rope from shore partners.
