Wapama Falls is a thundering seasonal waterfall in California's Hetch Hetchy Valley, drawing hikers with its dramatic cascades, granite scenery, and serene reservoir views.
Wapama Falls drops dramatically from the northern rim of Hetch Hetchy Valley in Yosemite National Park, fed by the seasonal snowpack of the Sierra Nevada high country. The falls have long been central to the identity of this quieter corner of Yosemite, which was flooded in 1923 to create the Hetch Hetchy Reservoir that supplies water to San Francisco.
The hike to Wapama Falls begins at O'Shaughnessy Dam and follows a well-maintained trail of roughly five miles round trip. The path hugs the reservoir's edge, passing through oak and bay laurel woodland before opening onto granite ledges with sweeping water views. The final approach leads to a series of wooden footbridges directly in the falls' path.
Spring visitors encounter the falls at their most powerful, when snowmelt sends white sheets of water cascading over the cliff face. By late summer the flow slows considerably, revealing the polished granite beneath. Wildlife is abundant year-round, with black bears, mule deer, and osprey commonly spotted along the trail.
Hetch Hetchy sees far fewer visitors than Yosemite Valley, making Wapama Falls a rewarding destination for those seeking genuine solitude alongside spectacular scenery.
Visit in April or May when snowmelt is at its peak and Wapama Falls runs at full, dramatic force.
Wear water-resistant footwear since the footbridges at the base of the falls are frequently soaked with spray and overflow.
Start your hike early in the morning to avoid afternoon heat, as the Hetch Hetchy trail offers little shade.
Bring binoculars to spot raptors and black bears that frequent the oak woodland and granite slopes along the route.
Check road and trail conditions before you go, as Hetch Hetchy Road has seasonal closures and limited visitor access.
