Upper Lena Lake Trail

Why go

If you’re after a true Olympic backcountry feel without days of travel, Upper Lena delivers. You start on the popular Lena Lake Trail and quickly leave the crowds behind, climbing into old‑growth forest, wildflower meadows, and a glacially carved subalpine basin wrapped in rugged peaks. It’s strenuous and long, but the payoff—clear water, big mountain views, and relative tranquility—is worth the grind.

Route and mileage

This is an out‑and‑back that begins at the Lena Lake/Brothers Trailhead on Lena Lake Trail #810, then turns onto Upper Lena Lake Trail #811 to reach the lake. Plan for about 14.6 miles total (7.3 miles one way). The lower trail is well‑maintained; the upper section is steeper, rougher, and more rugged. Expect stream crossings (notably Lena Creek) and rooty, rocky tread near the top. Most hikers do this as a long day (8–12 hours total) or an overnight.

What you’ll see and feel

The first miles wind through dense second‑growth and pockets of old‑growth, with rushing water close by. As you climb higher, the forest opens to occasional peek‑a‑boo views and seasonal wildflowers—trillium, avalanche lilies, columbine, and bleeding hearts in early summer. The lake itself sits in a classic glacial basin ringed by ridges that can hold snow into midsummer. It’s quieter than the lower lake, and the wilderness character really kicks in after the junction.

Camping and regs

Upper Lena has designated campsites with community bear wires and simple toilet facilities. A backcountry/wilderness permit is required for any overnight stay, and campfires are prohibited—bring a stove. Water is plentiful (Lena Creek and the lake), but treat it. You’ll cross from national forest into the national park on the way up—no dogs are allowed past the park boundary. Stock and bicycles are not permitted in the park segment.

Season and conditions

Best window: early/mid‑July through September for snow‑free travel and prime wildflowers. Earlier, expect lingering snow on the final approach and potentially high water at creek crossings. In any season, the upper trail can be snow‑covered; you may need map/compass skills and, when snow is present, an ice axe and the ability to self‑arrest. Weather flips fast here—pack rain layers even on bluebird mornings.

Tips from a friend

• Start early. The lower trail can be busy, and you’ll want daylight for the steep upper miles and any creek fords.
• Trekking poles help on the steeps and crossings.
• Parking requires a pass; buy ahead—there’s no pay station at the trailhead—and secure your vehicle (break‑ins have been reported at times).
• If you only want crowds and easy strolling, turn around at Lower Lena; if you want solitude and alpine scenery, keep grinding to the upper lake.
