Slate Peak is a 7,440-foot (2,270-metre) mountain summit located on the shared border between Okanogan County and Whatcom County in Washington state. It is part of the Okanogan Range, which is a sub-range of the North Cascades. The mountain is situated 15 miles (24 km) northwest of Mazama, on the boundary line of the Pasayten Wilderness, on land managed by Okanogan National Forest. The peak has the distinction of having the highest road in Washington, as well as the highest fire lookout. Although the narrow one-lane white-knuckle road reaches the summit of the mountain, the Forest Service gated it to vehicles, which necessitates walking the final few hundred yards. Additionally, the Pacific Crest Trail traverses the west slope of the peak, and the West Fork Pasayten Trail traverses the eastern slope. The nearest higher peak is Devils Peak, 2.57 miles (4.14 km) to the north. Precipitation runoff from Slate Peak drains east into Pasayten River, or west into Slate Creek, which is in the Skagit River drainage basin.It couldn't be easier to arrange your visit to Slate Peak and many more Winthrop attractions: make an itinerary online using Inspirock's Winthrop trip planner.
Slate Peak reviews
Went 8/4/19, and feel I should give some hints and tips for those interested. For us, it took us a good hour to hour and half from Mazama store to the peak, simply because the road was in bad shape..... more »
If you are not afraid of exposure and dirt roads take this drive to what feels like the top of the world! more »
Highest drivable road in the state. Fantastic view!
You almost drive to the top of this 7440 foot peak along the Cascade Crest north of Harts Pass. It is one of my favorite places to take visitors to showcase the east side of the North Cascades. You see everything up there! On a clear day you can even see Mt Baker. The drive by itself is a scenic adventure. The trail for the last half mile is short, but steep, and high altitude. A lookout tower still stands up there, but the cold war radar stuff is gone. Note how they leveled the top off. Best views are in fall when the western larch turns orange.
