This route was planned by komoot.
The hike to Lower Lena Lake is approximately 6.0 to 7.2 miles round trip. Most hikers complete the round trip in about 3 to 4 hours, though komoot's data suggests an average duration of around 1 hour and 35 minutes one way, depending on pace and stops.
Yes, this trail is considered of moderate difficulty and is very suitable for families and beginners. The well-maintained path is often wide enough for 2-3 people, and the elevation gain is made manageable by a series of switchbacks. It's even described as a good introduction to backpacking.
The trail begins at the Lena Lake / Brothers Trailhead, located in the Olympic National Forest. There is a parking lot at the trailhead, but it can fill up quickly, especially during peak season. Arriving early is recommended to secure a spot.
The trail ascends through a beautiful mix of second-growth and old-growth timber, featuring towering hemlocks and Douglas firs draped with moss and ferns. You'll hear Lena Creek along the way, crossing it via a bridge. As you climb, you'll encounter well-maintained switchbacks, small feeder streams, and impressive geological features like gigantic boulders and a massive rock overhang. In spring, native rhododendrons add a fragrant touch.
Beyond the stunning old-growth forests and geological formations, the main destination is Lower Lena Lake itself, a pristine, glacier-fed lake perfect for summer swimming. About three miles into the hike, an open ledge provides panoramic views of the lake, offering a great spot to rest and take in the scenery. You can find this viewpoint marked as View of Lena Lake.
The trail is best enjoyed from May through September when the weather is mild and the rhododendrons may be in bloom. However, it is open year-round. If hiking in winter, be prepared for snow and ice, and consider bringing waterproof boots, good grip, and potentially spikes.
Yes, dogs are welcome on the Lower Lena Lake Trail. However, they must be kept on a leash at all times to protect wildlife and ensure the safety and enjoyment of all trail users.
The Lower Lena Lake Trail is located within the Olympic National Forest, which typically requires a Northwest Forest Pass or an America the Beautiful Pass for parking at the trailhead. Always check the latest regulations with the Olympic National Forest service before your visit. This trail does not require an Olympic National Park entrance fee, as it is outside the park boundaries.
Yes, the Lower Lena Lake Trail serves as a gateway to more strenuous adventures. It is part of the Lena Lake Trail #810 and also provides access to the Upper Lena Lakes trail and The Brothers Trail #821. The route to Upper Lena Lake, however, enters Olympic National Park and requires permits, and dogs are not allowed on that section.
Yes, Lower Lena Lake offers a sprawling, first-come, first-served hike-in campground with developed campsites. It's a popular spot for backpackers, especially during peak season, so plan to arrive early if you intend to camp.
Given its moderate difficulty and potential for varying weather, it's advisable to pack layers of clothing, plenty of water, snacks, a first-aid kit, and navigation tools. Depending on the season, waterproof gear and appropriate footwear (like hiking boots) are essential. Don't forget your camera for the scenic views!
