Rock Creek Lake (Inyo National Forest, CA)
Campground · Mammoth Lakes corridor
Rock Creek Lake sits at 9,724 feet in the Mammoth Lakes corridor of California's Sierra Nevada, a high-elevation alpine lake in Inyo National Forest. Sheltered by peaks from the open desert to the east, it runs cooler and calmer than lower Mammoth Basin waters.
Wind funnels down the Rock Creek drainage in afternoon hours, typically gusting to 10 mph on the 30-day average and reaching 33 mph in sustained spring patterns. Morning hours hold the gentlest conditions. Cold, thin air means temperature swings are sharp; expect frost even in early summer.
Over the last 30 days, Rock Creek Lake has averaged a NoGo Score of 14.0 with winds at 10 mph and temperatures holding at 30 degrees Fahrenheit. The week ahead will track seasonal spring patterns. Wind typically peaks mid-afternoon; plan water and outdoor activities for early morning or late evening to avoid the afternoon build.

About Rock Creek Lake (Inyo National Forest, CA)
Rock Creek Lake (Inyo National Forest, CA) lies in the high Sierra between Mammoth Lakes and the White Mountains, accessed via Highway 395 and the Rock Creek Road drainage. The campground sits at 9,724 feet, making it one of the highest developed recreation areas in the Mammoth corridor. Drive time from Mammoth Lakes town is roughly 30 minutes southeast. The site occupies a glacial cirque with limited exposure to open wind but reliable afternoon updrafts funneling from the creek valley below. Highway 395 is the primary artery; Rock Creek Road branches east off the highway and climbs directly to the lake.
Conditions at Rock Creek Lake are shaped by extreme elevation and a north-south drainage alignment. Over the past 30 days, the 30-day average wind has held at 10 mph with peak gusts reaching 33 mph. Temperatures average 30 degrees Fahrenheit, ranging from overnight lows near 13 degrees to daytime highs around 44 degrees across the full year. Spring and early summer bring afternoon wind intensification as solar heating drives air up the Rock Creek drainage. Crowding averages 8.0 on a 100-point scale, meaning mid-week visits encounter far fewer visitors than weekends. Late season snow may linger into early summer; confirm road and trail conditions before traveling.
Rock Creek Lake suits anglers, backpackers, and day-hikers seeking high-elevation Sierra scenery without the Highway 120 corridor crowds. The lake itself is small and cold; most visitors fish for alpine trout or use the site as a base for backcountry trips into the Inyo National Forest. Parking fills on weekends during snow-free months. Morning calm and low crowding (8.0 average) make Tuesday through Thursday ideal for planning. Avoid afternoon hours if you're paddling or spending extended time on exposed water. Bring wind-resistant layers; temperature swings from 30-degree mornings to 40-plus daytime peaks are routine.
The Mammoth Lakes corridor offers multiple alternatives within short drive times. Convict Lake lies south on Highway 395 at lower elevation and typically warmer. June Lake Loop provides shelter and higher base popularity. Visitors balancing access, elevation, and true alpine character often pair Rock Creek Lake with a Mammoth Lakes town base, using the high site for day trips or overnight camping rather than as a sole destination.
