Here's a nice 3 mile snowshoe or cross-country ski in the winter. OR...you may be able to drive within about a half mile in the summer. For a good ski experience, you might want to have at least 3 to 5 feet of snow on the ground - see the depth measure in the first photo below.
The activation zone for Cooper Mountain is a (very) short hike above the dog park at Winkelman Park, 10139 SW 175th Ave, Beaverton, Oregon. There is no AZ access from Cooper Mountain Nature Park to the west and the summit proper is posted "No Trespassing."
"5580" is a four-point summit approximately 25 miles northeast of Prineville, OR. It is fairly easy to reach by roads with a short pack to the summit. The summit was activated for the 1st time on 24-Nov-2018 by Roland - K7FOP and myself Shelby -N7SHG.
UPDATE Dec 2021 - Badger Butte (and other summits in the area) are not accessible from Dec 1 to April 1 due to closure of NF-48 and other routes to vehicles more than 50 inches wide. SO - if there's snow and you've got a snowmobile, have at it. See the photo below.
Here's a nice 2.4 mile round trip hike on a quiet forest road, east of Prineville. Don't get this Wildcat Mountain mixed up with the other three summits with the same name in Oregon.
Humbug is a great hike on the South Coast, even if it is a steep six miles round trip and 1700 feet of gain. Find the well-marked and large parking lot for the trailhead about five miles south of Port Orford, Oregon on the west side of Highway 101. No parking pass is required.
After you climb about a mile, there is a slightly shorter (and slightly steeper) option to take the West Trail - I suggest that you try both, as the West has some nice peak-a-boo views, and the East has some amazing old growth. All trails are well-graded and likely busy during the summer months.
I had mapped out three different routes to the summit “trailhead” and opted to drive up from the south off Nestucca River Road. Turn north at an unmarked road/intersection .7 miles west of the NW Boundary Road/Nestucca River Road intersection. Most roads in this area are unsigned.
This is a short one mile hike 400 feet of gain that you reach by driving about five miles on a poor road. There's some bushwacking required to make the Activation Zone.
An easy one pointer in the Coast Range with a very short hike - using a GPS may help you find it in the maze of roads that is the Tillamook State Forest.
Rogers Peak is the highest point in Tillamook County and the highest also in W7O/NC. It's fairly easy to access, given a good road that is fine for passenger cars, a road walk after a gate, and a final ascent using an overgrown cat track that leads you almost directly to the summit.
