Kolana Rock
Peak · 5,774 ft · Yosemite corridor
Kolana Rock is a 5774 ft peak in the Yosemite corridor of California's Sierra Nevada, sitting above Tenaya Lake on the Highway 120 corridor. A scramble destination with avalanche terrain.
Wind accelerates off Tenaya Lake by mid-afternoon, pushing gusts to 26 mph in spring. Morning calm typically holds until late morning. Exposure on the approach means afternoon conditions deteriorate faster here than in sheltered valleys.
Over the past 30 days, Kolana Rock has averaged 9 mph wind and 38 degrees Fahrenheit, with a NoGo Score averaging 32. Crowding has been light at 3 on the scale. The week ahead will test whether calmer windows persist or afternoon wind dominates as it typically does in spring.

About Kolana Rock
Kolana Rock stands at 5774 feet on the north shore of Tenaya Lake, reached via Highway 120 east of Yosemite Valley. The peak sits roughly 40 minutes from the valley proper and 90 minutes from Lee Vining. Access is straightforward from the Tenaya Lake trailhead parking area on Highway 120; the scramble ascends talus slopes and rock bands without technical climbing. Winter and early spring require avalanche terrain awareness. The peak commands views across the Cathedral Range and down the Tenaya drainage.
Spring and early summer bring the most unstable conditions. The 30-day average wind of 9 mph masks afternoon gusts to 26 mph, typical for a high-Sierra peak exposed to lake-driven convection. Morning temperature hovers near 38 degrees Fahrenheit in spring; afternoon heating can raise it to the low 50s, but wind chill cuts that gain. Crowding remains light at a 3 on the scale, lower than Cathedral Peak or North Dome. Winter snowpack persists through late spring, converting the approach to a snow-climbing problem; check SAC avalanche forecasts before committing.
Kolana Rock appeals to scramblers comfortable with loose rock and moderate exposure, not backcountry skiers or casual walkers. Experienced Sierra peakbaggers often pair it with nearby Tenaya Peak or Cathedral Peak in a single morning. Afternoon wind makes solo or inexperienced parties vulnerable; many visitors quit the summit block by noon and descend. Parking fills on weekends in summer, but crowding in spring and fall stays minimal. Water is absent on the peak itself; carry reserves for the approach.
Cathedral Peak lies 3 miles south across Tenaya Lake and offers technical climbing rather than a scramble. North Dome, accessed from the same Highway 120 corridor further west, is a longer hike with more stable afternoon conditions due to its lower elevation and different exposure. Tenaya Lake itself is closed to boats but open to swimming and fishing; many visitors combine a Kolana Rock morning scramble with a lakeside swim. Smoke from late-summer fires can degrade views and air quality; check current conditions before scheduling a summit day.
