The summit proper of Cady Mountain is privately owned and not accessible.
It may be possible to activate from the narrow dirt road in lower portion of the Activation Zone, but it would be challenging.
Note that this is NOT W7O/CC-021 - Old Blue or W7O/SC-066 - Old Blue Mountain.
When approaching from BLM Road 10 off of Highway 35, Old Blue Mountain, near Marys Peak, is gated and posted as private property. It appears that the peak itself may be on public lands, but the access from the south passes through Weyerhauser timberland.
There may be other access on other roads that approach from another side of the peak.
Pansy Mountain is a challenging activation with a steep cross-country approach for the last half mile. Be sure to use a GPS or have a fantastic sense of direction so you can find you way BACK to the trail.
Mount Bailey near Diamond Lake is a great hike to fantastic views but it requires some effort to get those views - with a hike of about 10 miles round trip
Here's another summit in the Diamond Lake area to activate if you have a few hours. It's a drive-up, if your vehicle has moderate ground clearance and otherwise a short road hike.
Here's another summit in the Diamond Lake area to activate if you have a few hours to spare - it's a short hike, but there's no trail. And note that there are three Oregon summits with this same name.

Bates Point (Peak 2360) is a drive-up summit in the Coast Range of Oregon - specifically in the Tillamook State Forest. Roads in the Tillamook Forest are usually good - however the signage and documentation are remarkably poor. What's on the ground doesn't necessarily match your GPS map or what in Google Earth and vice versa.
Ben Smith (Peak 2592) is a summit with a short but steep hike in the Coast Range of Oregon - specifically in the Tillamook State Forest. Roads in the Tillamook Forest are usually good - however the signage and documentation are remarkably poor. What's on the ground doesn't necessarily match your GPS map or what in Google Earth and vice versa.
Just north of Detroit, Oregon are a nice bunch of summits - Dome Rock is especially good. The Tumble Ridge Trail takes you to Dome Rock on a pleasant forest hike of only about 1.5 miles and 500 feet total gain.
