Sitting in a peaceful little cirque on a ridge high above the Sauk River is pretty little Peek-a-boo Lake. Unimposing and tucked away in a rugged landscape, the hike is short but the going is a little tough. Rocky and rooty tread helps keeps your pace from speeding up. But that’ll just give you more time to marvel at the surrounding beautiful primeval forest.


The trail begins in impressive old-growth forest.

The trail begins on an old logging road in scrappy forest, but quickly transitions to true trail in impressive old growth. Climbing gently at first, the grade soon intensifies leading up a thickly forested 4,350-foot ridge. Massive hemlock, fir, and cedar as well as babbling brooks and a lush understory of greenery help keep your attention off of the climb.

The trail then begins to lose some of that hard-earned elevation gain, and after a half mile breaks out into a picturesque parkland meadow. Pass by a delightful little tarn and continue through more meadows. Using care not to trounce delicate vegetation, leave the trail for the eastern edge of the meadow for a breathtaking view of White Chuck Mountain and Mount Pugh hovering over the Sauk River Valley.


White Chuck Mountain can be seen along the way.

Peek-a-boo still waits, so head back to the trail where it returns to forest dropping about 300-feet on rough tread to the placid body-of-water in an emerald bowl of stately evergreens. Now enjoy Peek-a-boo Lake fully revealed. A refreshing swim-an afternoon nap-a little fishing-or just an afternoon of pure relaxation!
