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.
John, Ralph and myself (Eric) made the trek to the summit of St Marks. The hike is very popular with 200+ on the trail on a nice week-end. The first half of the trail is well groomed and easy walking. The trail improvement stops about half way and from there on the trail is easy to follow but it is very root infested and so one needs to be constantly watching where one steps.
Directions: Take Sunset Falls Road east of Battleground to Sunset Campground. Turn right and cross the East Fork Lewis River on FS Road 41. Stay on FS 41 for approximately 9 miles to a large parking area atop McKinley Ridge. This is NOT the summit.
Poor McDonald, like Rodney Dangerfield, it gets no respect. And honestly, that’s not fair. Sitting in line with the heralded Mt. Ashland (W7O/CS-019), McDonald is easy to access, has a great operating position, and spectacular views of the Siskiyous in all directions. If you are activating Mt. Ashland, you absolutely must make it a double if the roads are open and clear.
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.
Zero Butte is just west of Condon, Oregon and is an easy drive-up summit. Take Highway 206 4.5 miles west from Condon and turn (left) west onto Richmond Road. Continue 1.5 miles to an unmarked dirt road heading off to the left. This is about where the unexpected subdivision ends and where what looks like a former military installation begins. The dirt road was easily passible in a passenger car for the 0.9 miles to a fence and a gate where the high point is located.
Grizzly Mountain is an easy drive-up summit about 9 miles west of Prineville. The views are great and the road passable in a passenger vehicle - perhaps slowly in the rocky places.
