About Tamarack Lakes Trailhead
Tamarack Lakes Trailhead is the main jump-off for the Tamarack Lakes basin in the Mammoth Lakes corridor of California's Sierra Nevada. Located on the east side of the range at 9,744 feet, it sits just south of the Inyo National Forest boundary and draws hikers and backpackers heading into the glacially-scoured Tamarack Lakes drainage. Access is via Highway 395 to Mammoth Lakes, then secondary roads toward the trailhead parking area. The route is snow-gated and impassable during winter runoff; confirm road status before driving. Spring arrival times depend on snow melt in the high passes.
Conditions here pivot sharply on time of day. Early mornings are characteristically calm; wind typically arrives by mid-afternoon as thermal circulation kicks in off the exposed ridges and lake basins. Over the last 30 days, the 30-day average wind speed of 10 mph masks a range from near-calm to 33 mph gusts. Temperature averages 30 degrees Fahrenheit in the current rolling window, but annual extremes swing from 13 degrees in winter to 44 degrees in peak summer. Crowding averages around 8 on the 30-day rolling window, meaning parking fills quickly on weekends and holidays. Smoke from Sierra fires can degrade visibility in late summer and early fall. Snow lingers into late spring at this elevation.
Tamarack Lakes Trailhead suits backpackers and day hikers with high-altitude tolerance who are willing to plan around afternoon wind. The basin itself offers alpine lakes, cross-country scrambling, and low-key camping. Most users are experienced Sierra trekkers who pack shelter and water systems for changeable weather. Plan to start early, be off-peak by 2 p.m., and carry wind-resistant gear even in summer. Parking is limited; arrive by 7 a.m. on weekends to secure a spot. Water is available at the lakes but requires treatment. The trailhead serves as a gateway to the Mammoth Lakes drainage's quieter eastern approaches.
Nearby alternatives include Duck Lake and Arrowhead Lake trailheads, which offer similar alpine exposure but lower crowds on weekdays. Mammoth Lakes town sits lower and warmer, with restaurants and services; it is the primary supply point before heading to the trailhead. The Inyo National Forest extends north and south with dozens of high-Sierra trailheads along Highway 395; Tamarack Lakes appeals to users seeking a quieter route into the range compared to the busier Mammoth Main Street corridor approaches.
