Excellent for either a quick day hike with an afternoon swim or a weekend camping trip, Lena Lake offers a variety activities for both the two- and four-legged alike. The Lena Lake Trail is well maintained and does not exceed anything more than a moderate grade, which makes it ideal for families, trail runners, and those looking to trek further out into the surrounding valleys and Olympic Mountains.

What Makes It Great

Lena Lake, a naturally formed alpine lake created by a rockslide some 1,300 years ago, provides a retreat into the Olympic National Forest and acts as a springboard for other ventures such as climbing The Brothers, trekking to Upper Lena Lake, or indulging in photographing the Valley of the Silent Men. The trail up to Lena Lake is wide and of moderate grade with plenty of switchbacks to make the journey easier and more enjoyable. Once at the lake there are campsites nestled in the old growth forest against the lake but these sites can fill up quickly on a sunny summer weekend. Delighting in a well deserved dip is a fantastic way to enjoy the lake on a more heated afternoon.

Beyond Lena Lake, there is the option to trek west along trail #811 to Upper Lena Lake which is settled another four miles away. Dogs are not permitted at Upper Lena Lake as it is part of the Olympic National Park. More solitary camping and views of Mt Lena can be found at this lake but be sure to obtain your permits through the Olympic National Park service.

Another stunning day trek beyond Lena Lake is through the Valley of the Silent Men along The Brothers trail, trail #821. The trail is less maintained but is teeming with captivating sights of emerald waterfalls and creeks embraced by carpets of velvety moss and a dense canopy of vibrantly green conifers. Continuing on this trail ends at the climber's camp for The Brothers for those looking to scramble to its summit.

Who is Going to Love It

Anyone looking for an ideal summer weekend camping trip with family and friends, with a chance to cool off in an alpine lake, will savor Lena Lake. The additional trails beyond the lake also provide a gateway for those seeking more solitude or the chance to spend a day photographing the beauty of the surrounding valleys.
