This is a easy out and back trail (totaling about 9 miles) on the Cle Elum Ranger District of the Okanogan Wenatchee National Forest. A popular introductory backpacking trip, the trail is frequented by families. It is also an excellent day hike or horseback ride, so be sure to yield to equine groups along the trail. The trail winds its way gently along the Cooper River valley with a few ups and downs along the way, a few small stream crossings vary seasonally. The mosquitos will keep you moving, but watch out for roots and rocks! When you reach the lake enjoy the quiet waters and views of the Cascade Crest including Chimney Rock and Big Summit Chief. There are campsites at several spots along the shore. More private campsites can be found along the north side. If you’re feeling adventurous follow the trail further to connect to the PCT which gains acces to Spectacle Lake to the west or Lemah Meadows to the east.
This trail goes by Pete Lake.
From the town of Roslyn Washington, follow state route 903 until it becomes Salmon la Sac road as it borders lake Cle Elum. After the slow winding drive along the lake, keep an eye out for Forest Service Road 4600. Take the left to follow this road across the Cooper River and wind another 4.7 miles up, turn left onto Forest Service Road 4616. Continue past Cooper Lake for another mile until you reach the fork, be sure to follow the signs and park in the correct lot. This area is shared with stock so please don’t block the trailer parking lot! The trailhead is located at the far end of the lot. A Northwest Forest Pass, America the Beautiful Pass, or day use fee are required for parking. Discover Passes (state passes) are not valid on federal lands. Going all the way to the lake does cross into Wilderness Area, so please fill out a permit and leave the appropriate portion in the box. This trailhead is very popular so go early! For a quieter hike try a week day.
This is a very popular trail for young and old. Many kids enjoy their first backpacking trip along the shores of Pete Lake.
