Smith Peak
What to Expect
Safety Advisory
The final summit approach crosses exposed granite slabs with significant drop-offs on the north side. Stay well back from the edge, especially in windy conditions or when rock is wet.
Afternoon thunderstorms are common from June through September at this elevation. If you hear thunder or see cumulonimbus clouds building, descend immediately — the summit is the worst place to be in a lightning storm.
Trail Details
Pro Tips
Start from the shorter trailhead six miles past the Big Oak Flat entrance station to shave significant distance — the alternate start from Hetch Hetchy adds several miles and more elevation.
Carry at least three liters of water per person. There are no reliable water sources on the upper half of the route, and the exposed summit push on a warm day will drain you faster than you expect.
The summit view toward Hetch Hetchy Reservoir is best in morning light when the water glows turquoise — plan to top out before noon for photography and to avoid afternoon thunderstorms.
