Chipmunk Flat Campground
Campground · Yosemite corridor
Chipmunk Flat Campground sits at 8009 feet in the Yosemite corridor's high Sierra, positioned where afternoon wind funnels down the drainage. A sparse, exposed site favored by climbers and early-season visitors.
Wind dominates here. The 30-day average runs 11 mph, with afternoon gusts common. Mornings are calmer; afternoons blow steady. Temperature swings from overnight frost to mild midday warmth. Crowding stays light due to elevation and sparse amenities.
Over the last 30 days, Chipmunk Flat averaged a NoGo Score of 17 with wind averaging 11 mph and temperatures near 29 degrees Fahrenheit. The week ahead will show typical spring variability at this elevation: watch for afternoon wind picking up and crowding starting to climb as the high Sierra access window widens.

About Chipmunk Flat Campground
Chipmunk Flat Campground occupies a high-elevation clearing in the Yosemite corridor of California's Sierra Nevada, accessed via Highway 120 from the west or Highway 395 approaches from the east. The campground sits at 8009 feet, well above the valley floor and in the transition zone between mixed conifer and high-Sierra granite. Primary access is via Highway 120; the drive from Highway 395 at Lee Vining takes roughly 2 hours. The site is sparse and undeveloped compared to lower Yosemite-corridor options, which limits crowds but also means no running water or ranger presence during shoulder season.
Conditions here follow elevation and aspect strictly. The 30-day average temperature of 29 degrees Fahrenheit reflects spring conditions; by midsummer, daytime highs exceed 50 degrees Fahrenheit but overnight lows remain near freezing. Wind averages 11 mph over the last month with gusts to 31 mph; afternoon wind is dominant and predictable, driven by heating of the valley floor below. Crowding averages 12 visitors over the rolling 30 days, sparse even by Sierra standards. Late September through early October delivers the calmest and warmest stretch; spring opening can see heavy wind and lingering snow. Winter closures are common due to snowpack.
Chipmunk Flat suits climbers working nearby granite routes, backpackers staging longer Sierra traverses, and visitors seeking isolation away from Yosemite Valley noise. Expect exposed campsites with minimal shelter; high wind afternoons are routine. Parking is tight; arrive early. The elevation means early-season snow melt and afternoon lightning risk in summer are real. Experienced high-Sierra users plan cooking and exposed activities for morning hours and retreat to tents by mid-afternoon when wind builds.
Nearby Tioga Lake and Lee Vining Creek offer similar high-elevation exposure but with different access timing. Ten Lakes and Cathedral Lakes are warmer and lower, with better afternoon shelter. Yosemite Valley and Wawona Meadow are 30 to 45 minutes downslope and typically 8 to 12 degrees Fahrenheit warmer, with far heavier crowds. Chipmunk Flat's value is solitude and proximity to climbing; trade amenities and warmth for that advantage.
