Hartley Springs Campground
Campground · Yosemite corridor
Hartley Springs Campground sits at 8474 feet in the high Sierra east of Yosemite Valley, offering alpine camping sheltered from afternoon wind by surrounding ridges.
Wind accelerates in early afternoon as thermal currents rise off the surrounding peaks, typically gusting to 30 mph by midday. Mornings are calmer and colder, often near freezing even in late spring. Late-day wind funnels down the drainage; head out early if you're sensitive to exposure.
Over the last 30 days, Hartley Springs averaged 10 mph wind with temperatures around 36 degrees Fahrenheit and a NoGo Score of 15. The week ahead will show similar patterns: watch for afternoon wind gusts and expect snow or rain at elevation during the shoulder season.

About Hartley Springs Campground
Hartley Springs Campground lies in the Yosemite corridor on Highway 120 (Tioga Pass Road) east of Tuolumne Meadows, roughly 50 miles from Yosemite Valley via CA 41 and CA 120. The campground sits at 8474 feet on the eastern flank of the Sierra crest, positioned between alpine meadows and conifer forest. Access is most direct from Lee Vining or June Lake to the east via Highway 395 and Highway 120; from the west, Highway 120 is the only corridor route and often closes November through May due to snow. The campground serves as a staging point for hikers bound for high passes and peak-baggers targeting the Sierra crest.
Typical conditions mirror the high-elevation shoulder season: the 30-day average temperature is 36 degrees Fahrenheit with sustained winds averaging 10 mph and occasional gusts to 30 mph. Crowding averages 12 (a baseline metric) across the rolling 30 days, well below the summer peak. Early morning is substantially calmer than midday; thermal wind starts rising around 10 a.m. and dominates through sunset. Snow cover persists into late May at this elevation, and late-spring storms can dump fresh snow without warning. By late June, afternoons are reliably clear but windy. Late summer brings lower crowding than July-August and more stable weather, though afternoon thermals remain consistent.
Hartley Springs suits climbers, peak-baggers, and backpackers targeting the Sierra crest and multi-day high-country traverses. Campers should expect limited facilities, sparse water sources, and reliable afternoon wind. Experienced high-altitude campers plan around early-morning starts, avoid midday exposure, and carry four-season shelter. The site is best for self-sufficient parties comfortable with exposed terrain, thin air, and rapid weather shifts. Families with young children and car-camping comfort expectations should consider lower-elevation alternatives on the corridor.
Nearby Tuolumne Meadows Campground (Highway 120 west) offers more facilities and water but similar wind and elevation exposure. Lee Vining and June Lake to the east provide warmer, lower-elevation base camps with better services. Mono Basin scenery and the Eastern Sierra front dominate views from Hartley Springs; the corridor offers fewer crowds than the Valley but demands self-reliance and respect for high-alpine conditions.
