Visited in the spring of 2015. The hike to lower Lena Lake is good for a day trip but rather short for an overnight backpacking trip in my opinion. It's on the Olympic peninsula so be prepared to drive and experience some rain. We set up camp at the lower lake then hiked up to the upper. It was incredible really, because while lower Lena was in full on spring upper Lena was still locked in the grip of winter. I recommend this hike for beginner and intermediate hikers as a potential introduction to the Olympic peninsula.
