This summit is a short distance off Langlois Mountain Road (Langlois, Oregon).
However, it is behind a house with a loose, barking dog and one would need to walk up the driveway and pass only a few feet from the house to access the summit. This is likely private property.

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.
Peak 3410 is about 10 miles back into the Tillamook State Forest. Although once you get there it is really a near drive-up, the drive on those roads might feel like you've been hiking five miles by the time you get there. You'll want a high clearance vehicle, a good map, and GPS to reach this summit off Highway 6.
Here is a lovely hike in the south reaches of the Clackamas watershed. The hike is about 6.5 miles round trip and 1000 feet of gain. Although about two hours from Portland, it's also a nice drive to the trailhead with good signage along the way. Only the last half mile or so would be challenging in a passenger car.
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.
UPDATE March 2023: W7O/WV-069 has been retired.
Blowout Benchmark is a short hike and cross-country summit near Detroit, Oregon. There are no views but you get to enjoy the quiet of a second-growth forest.
Peak 3700 is a bit of an adventure, but certainly do-able summit near Detroit, Oregon. You'll follow a long-abandoned logging road and head cross-country for the final ascent into the Activation Zone. There are no views and the final ascent is very rough, but you get to enjoy the quiet of a second-growth forest.
Here's an out of the way summit south of Prineville, Oregon with nice views and plenty of quiet. The drive towards the summit on Highway 27 is along the Wild and Scenic Crooked River and is lovely in itself with nice camping opportunities.
