Little Willow Lake Trailhead
Trailhead · North Sierra corridor
Little Willow Lake Trailhead sits at 6168 feet in California's North Sierra corridor, serving as the primary gateway to a glacially-carved alpine lake. The location sits sheltered from the heaviest afternoon wind patterns that dominate exposed ridges nearby.
Morning hours bring calm conditions and the lowest wind; afternoon wind typically climbs to 9 to 10 mph by mid-day. The lake's elevation means rapid temperature swings between sun and shade. Expect the steadiest conditions Tuesday through Thursday mornings before weekend crowding peaks.
Over the last 30 days, the average wind at Little Willow Lake Trailhead has held at 7 mph with temperatures averaging 39 degrees Fahrenheit and a typical NoGo Score of 12. The week ahead should track close to that pattern. Head out early in the day; afternoon thermal wind and weekend congestion are the main friction points.

About Little Willow Lake Trailhead
Little Willow Lake Trailhead anchors the North Sierra corridor in the high country between Highway 395 and the main Sierra crest. The 6168-foot elevation places it in the transition zone between lodgepole forest and open alpine terrain. Primary access runs via Highway 395; the trailhead itself sits off a spur road in the Lassen Peak region. Nearby towns (Chester, Old Station) are 45 to 60 minutes away. The location draws backcountry hikers, lake fishers, and day-use trekkers targeting the lake proper and the surrounding cirque basin.
Seasonal weather at Little Willow Lake Trailhead swings dramatically. The 30-day rolling average sits at 39 degrees Fahrenheit with 7 mph average wind, but temperature extremes across the full year span 22 to 55 degrees Fahrenheit. Late spring and early fall offer the narrowest weather windows; peak snow typically blocks the trailhead from November through May. Wind gusts have peaked at 19 mph in recent months. Afternoon thermal wind is the dominant pattern; mornings stay flat until mid-day. Crowding averages 9 on a rolling 30-day basis, with weekends drawing double or triple weekday traffic once snow clears.
This trailhead suits experienced day hikers and backpackers comfortable with high-altitude exposure and rapid weather shifts. Fishers target the lake's cutthroat and brook trout populations. The location works best for visitors who can commit to early starts; afternoon wind makes the exposed lake crossing unpleasant for paddlers or less mobile hikers after 2 p.m. Parking is limited and fills by mid-morning on weekends. Snow patches linger on the north-facing slopes well into late spring, adding route-finding complexity. Bring layers and expect sudden cloud cover even on clear mornings.
Nearby cirque lakes offer similar terrain with slightly different exposures. The Lassen Volcanic National Park complex sits 30 to 40 minutes south and draws heavier crowds. The North Sierra corridor as a whole transitions from snow-dependent high lakes south of here to drier ridge terrain north toward the Modoc Plateau. Little Willow Lake Trailhead bridges the two zones; it offers easier access than the high passes further south and more reliable water than the dry basins to the north.
