There's a whole USGS quad named after this highpoint. Stimson Hill rises to 2,892’ with an impressive prominence of 1,852’. In fact, Stimson makes it into Washington States top 200 peaks by prominence.
Round Trip is approximately 7 Miles. If you search around for viewpoints, mileage could be added to this figure. Total elevation gain to the Summit is 2,600’.
When you leave the gate, you will ascend the logging road by foot. The typical summit route is a road hike. Most of the hike is through forested areas with lots of ferns and typical undergrowth. You can look back in some spots and start to see views of the Puget Sound as you rise quickly in elevation. The hike gains elevation (2,600’) the whole way up to the summit. Once you reach the true summit the views are great looking down on Arlington and out into the Puget Sound. The day I went, it was a bit cloudy which limited some of the views. You can hike from here to other highpoints to see amazing views of Three Fingers, Whitehorse, Big Deer Peak and other peaks in the local area. Some of the viewpoints will require some bushwhacking through Alders, Cascara and Willows. If you plan a visit to the true summit it is also recommeneded to also venture to some of these other highpoints for different views. The views from the true summit are not a true outward 360 degree, but visiting the other highpoints you should get views in most all directions.
At first glimpse Stimson Hill looks to be right on the border of Skagit and Snohomish County, which it is. However, looking closer the true summit of Stimson Hill is in Snohomish County. It's two other confirmed highpoints are in Skagit County.
Getting ThereTake Highway 9 north out of Arlington to Bryant. Turn east (Right) on Grandview Road for 4.6 miles, then north (left) on Cedarvale Road. A little over a mile you will come to a right corner in the road and will pass over rock creek drainage, immediately to your left you will see a yellow gate. Park here, but make sure not to block the gate. Follow the Stimson Hill Route Map below.
~Mount Washington~ Another option if you are in the area would be a northwesterly hike to nearby Mount Washington 2,698' with a prominence of 738'. Click here for route information. Mount Washington Page
Trip Report From 2010- NWHikers Trip Report
Red TapeNo Pass Required.
You should be able to reach the summit year round. This is a good area to visit when avalanche danger is high on steeper more higher elevation slopes. Snowshoes in the winter, when the snow level is that low.
The northwestern highpoint is great for Sunsets.
