Vermilion Lake
Lake · 10,551 ft · Mammoth Lakes corridor
Vermilion Lake sits at 10,551 feet in the Mammoth Lakes corridor, a glacial cirque lake framed by high-Sierra peaks. Calmer than the exposed basins to the east, it rewards early visits before afternoon wind and crowds arrive.
Morning glass water gives way to afternoon wind funneling off the surrounding ridges by mid-day. The 30-day average wind of 9 mph masks afternoon gusts that can reach 24 mph. Head here before 11 a.m. if you are paddling or photographing; skip the lake after 2 p.m. unless you want rough chop.
Over the last 30 days, Vermilion Lake averaged a NoGo Score of 36, with temperatures holding near 32 degrees Fahrenheit and crowding staying light at 4 out of 10. The week ahead shows typical spring variability: expect wind to pick up mid-week and calm mornings to remain the window for stable conditions. High-elevation snowpack is still present; approach avalanche terrain with caution if you plan to access drainages or steep couloirs feeding the lake.

About Vermilion Lake
Vermilion Lake lies in the high country east of the Mammoth Lakes basin, accessed via Highway 395 to Mammoth Lakes town, then Highway 203 west toward the Lakes Basin trailhead system. The lake sits at 10,551 feet on the eastern slope of the Sierra crest, in terrain drained by Sherwin Creek and bounded by ridges rising to 11,000-plus feet. The parking and trailhead lie on the north side; most approaches take 2 to 3 hours of hiking from the nearest established lot. This is not a walk-up destination; traffic is light relative to lower lakes, and the elevation and access filter casual visitors.
Vermilion Lake experiences a compressed season. The 30-day rolling temperature averages 32 degrees Fahrenheit, with the 365-day range spanning 20 to 50 degrees Fahrenheit, reflecting the elevation and late-spring timing when much of the access is still snow-covered. Wind averages 9 mph over the last month but spikes to 24 mph on the windiest days, typically in the afternoon as thermal circulation strengthens. Crowding stays low year-round (4 out of 10 for the month) due to the high elevation, remote trailhead, and snowpack that closes approach routes from late autumn through early summer. Expect stable conditions only on calm mornings; afternoons are reliably choppy.
Vermilion Lake suits high-elevation backpackers, mountaineers, and photographers seeking solitude and alpine scenery. The low base popularity (0.25) and high elevation mean you will rarely encounter crowded conditions, even on weekends. Visitors should plan around afternoon wind, avalanche exposure in steep drainages, and lingering snowpack that makes the approach hazardous outside the established hiking season. Bring layers; temperature swings from morning to afternoon can exceed 20 degrees Fahrenheit. Parking at the trailhead fills rarely; the real constraint is physical fitness and acclimatization to 10,500-foot elevation.
Nearby alternatives in the Mammoth Lakes corridor include Lakes Basin trails lower and more accessible than Vermilion, offering warmer water and easier approach. The Inyo National Forest access roads parallel Highway 395 and offer multiple cirque lakes at similar elevations with varying wind and avalanche exposure. Vermilion Lake's position on the Sierra crest means it is colder, windier, and more remote than comparable lakes west of the crest in Yosemite territory, making it a strong choice for mountaineers and backcountry purists rather than day hikers.
