Convict Creek Trailhead
Trailhead · Mammoth Lakes corridor
Convict Creek Trailhead sits at 7,569 feet in the Mammoth Lakes corridor, where creek drainage and exposed terrain funneling from the Sierra crest create reliably strong afternoon wind. A moderate-elevation access point to the high country.
Wind dominates. The 30-day average runs 13 mph, with gusts to 41 mph typical in afternoon hours as air funnels down Convict Creek canyon. Mornings are calmer; plan creek or lower-elevation activities before 10 am. Cold persists year-round; expect 25 degrees Fahrenheit average with winter lows to 7 degrees.
Over the last 30 days, the 30-day average wind of 13 mph and average score of 17 reflect typical spring volatility for this exposed trailhead. Temperature averages 25 degrees Fahrenheit with occasional days dropping to 5 or climbing toward 40. The week ahead follows the seasonal pattern: calm mornings, escalating wind by midday, higher crowding on weekends as Highway 395 access improves.

About Convict Creek Trailhead
Convict Creek Trailhead serves as the primary gateway to the Convict Lake basin and high-country routes in the eastern Sierra. Located at 7,569 feet on the eastern flank of the Mammoth Lakes corridor, it sits 5 miles south of Mammoth Lakes town via Highway 395 and Convict Lake Road. The trailhead parking area is immediate and uncrowded on weekdays; arrival by 7 am secures reliable spots. The location straddles open sagebrush and conifer forest, with direct exposure to wind funneling off Convict Lake and down the creek drainage toward the Owens Valley. Proximity to Highway 395 makes it accessible year-round, though winter snow closes Convict Lake Road at unpredictable intervals.
Wind and cold define the experience. The 30-day average wind runs 13 mph with maxima to 41 mph, driven by the gap between the Sierra crest and the valley floor. Afternoons are consistently windier than mornings; skip afternoon departures if you are sensitive to exposure or if you are carrying light gear. Temperature averages 25 degrees Fahrenheit across the rolling 30 and 90-day windows, with recorded minima to 7 degrees Fahrenheit in winter and maxima to 45 degrees in summer. Snow lingers into late June in high basins, but the trailhead itself clears by mid-May in most years. Crowding averages 8 on the 30-day rolling window, concentrated on weekends and holiday periods. Base popularity sits at 0.4, meaning the site draws local and regional traffic rather than bucket-list crowds.
This trailhead suits hikers targeting the Convict Lake cirque, climbers heading to peaks above 10,000 feet, and creek anglers working the upper drainage. Experienced Sierra users plan for early starts, afternoon descent, and wind-resistant shelter if camping. Parking fills by 9 am on sunny Saturdays; arrive Wednesday through Friday mornings to avoid queueing. Water is abundant (Convict Creek is year-round), but the creek runs glacial and cold. Cell service is spotty. The absence of avalanche terrain makes it safe for traversal in winter and spring, though snowpack and creek crossings demand careful footing.
Nearby Mammoth Lakes Trailhead (northwest, 8,400 feet) sits higher and more exposed; it clears later in spring but offers faster access to the Sierra crest. Horseshoe Lake Road and the Reds Meadow corridor offer alternative drainage patterns and lower crowding for those flexible on timing. Convict Creek's strength is reliable access and moderate elevation; choose it when Highway 395 is passable but high alpine routes are still snowbound or when you want creek-access activities without committed high-altitude exposure.
