Hiking Three Peaks and Mosquito Lake

The Three Peaks trail gets off to an unassuming start — following an abandoned road through the forest for half a mile. After departing from the road, hikers find themselves in a thick forest for several miles before the views open up a bit through timber harvest area. As hiker near the end, the trail crosses into the Goat Rocks Wilderness and rewards hikers with peek-a-boo views of Packwood Lake.

The Three Peaks trail ends at the junction with the Packwood Lake trail 4.8 miles in. Hikers can stop here and enjoy some time at the ominously named Mosquito Lake, or continue eastward at the junction to reach Lost Lake or Chimney Rock.
