Lower Lena Lake Trail Professional Review and Guide
"Dominated by a shoulder of The Brothers, this forest lake was formed thousands of years ago by a massive rock slide that dammed the valley. The “dam” leaks and the lake resembles a reservoir in that the water rises and falls with the season. Wading and swimming are possible, but even in summer the water is so cold that only a child will enjoy it. This is one of the most popular hikes on the eastern slope of the Olympic Mountains, so the trail is eroded by the thousands of feet that have traveled it. Expect many roots and rocks for little feet to tumble over.
The trail switchbacks through an area that was first logged by railroad in 1931. The half-century-old trees look pretty big until, at approximately ¾ mile, the trail enters old-growth forest, where you find the really big trees. At 1½ miles, the way crosses a dry streambed of Lena Creek, which runs underground most of the year. If time permits, explore the caves made by giant boulders lying on top of nature’s dam and marvel at the size of the trees growing on it. That rock slide was a long time ago! At 3 miles, reach the shore and outlet of Lower Lena Lake, at 1800 feet."
