Upper Pine Grove Campground
Campground · Mammoth Lakes corridor
Upper Pine Grove Campground sits at 9,446 feet in the Mammoth Lakes corridor of California's Sierra Nevada. A high-elevation base camp typically calmer than the open alpine terrain east of the Sierra crest.
Wind averages 10 mph but surges to 33 mph in the afternoon, driven by thermal heating of the surrounding basins. Morning windows close by mid-day. Temperature swings 13 to 44 degrees across the year. Expect dense crowds only in peak summer; shoulder seasons offer solitude.
Over the last 30 days, the average wind held at 10 mph with a high of 33 mph, while temperatures averaged 30 degrees Fahrenheit and crowding stayed light at 8 out of 10. The week ahead follows the seasonal trend: calm mornings, afternoon gusts, and sparse visitor traffic until late June. Watch for snow lingering at this elevation into late spring.

About Upper Pine Grove Campground
Upper Pine Grove Campground lies in the Mammoth Lakes corridor, accessed via California Highway 395. The campground sits at 9,446 feet, placing it above the valley floor but below the highest crest terrain. From Mammoth Lakes village, drive north on Highway 395 for roughly 10 minutes to reach the eastern Sierra approach. The site offers direct access to high-elevation hiking, fishing, and dispersed camping exploration. Proximity to the Inyo National Forest and nearby peaks makes it a natural staging point for multi-day alpine trips.
This location experiences the classic Sierra Nevada high-elevation weather pattern. Overnight temperatures drop to the low teens in winter and early spring; summer highs rarely exceed 44 degrees Fahrenheit. The 30-day average temperature sits at 30 degrees, reflecting the current late-spring conditions typical of this zone. Wind averages 10 mph but frequently gusts to 33 mph by afternoon as solar heating drives air up the drainages and over the ridges. Crowding remains light to moderate year-round, spiking only during summer school holidays. Snow persists at this elevation into June most years.
Upper Pine Grove works best for backpackers, peak hunters, and dispersed campers seeking high-elevation solitude without the infrastructure demands of lower-lying campgrounds. Experienced visitors plan morning-only activities, then retreat to camp or seek shelter before the afternoon wind arrives. The sparse base popularity (0.3) and low average crowding (8 out of 10) mean parking and site availability are rarely constraints, even on weekends. Bring layers; temperature swings of 30+ degrees between day and night are routine. Afternoon wind makes fishing impractical after mid-day and can render exposed ridges uncomfortable without shelter.
Nearby Upper Mammoth Lake and other high Sierra drainages offer similar exposure and similar afternoon wind regimes. Lower-elevation Mammoth Lakes village campgrounds provide warmer overnight temperatures and more amenities but attract heavier crowds. For those seeking true high-elevation camping with minimal amenities and minimal crowds, Upper Pine Grove offers a direct alternative to the busier roadside facilities along Highway 395.
