From Kettle Falls, WA proceed west on 395 across the lake to highway 20, then south along the west shore of Lake Roosevelt on Inchelium-Kettle Falls Rd. Proceed southwest on County Highway 412 past Lake Ellen, turn right on NF-2014 (aka Barnaby Creek Rd), then right again on Cottonwood Creek Rd (NF-110). Park at this intersection if you don't have a 4WD which adds less than a mile. If you have a 4WD, take this road to its terminus and park where the road becomes blocked by downed trees. As you hike along the road, it will eventually become Huckleberry Jeep Trail only useable by UTVs. This trail would not be MTB bikeable due to the large stones.
At 48.53409 -118.31149 leave the jeep trail and follow a small foot path over two sections of small false summits. You'll know the actual summit by the remains of an old fire lookout tower that was dismantled. Water is available to filter from several small springs along the jeep trail. Bear spray recommended.
