Today I tested my revision of the route I did that required way too much senseless hike-a-bike on Cook's Butte. With this version, More Lake Oswego Gravel, you still have to walk a short "pedestrians only" section through Beth Ryan Nature Reserve (though if no one is looking you can ride it--I did today). Also, when you get to Cook's Butte, the cross through is steep, rocky and rooty and I ended up walking most of it. Short sections of this ride are best with 2.2" or wider tires. Not sure I would do it with my 700x44s, but perhaps. There also are some steep grades that are challenging, particularly the single track on SW Hilltop Rd which I've managed to make both times I've tried it. I left my route to climb S. Bergis Rd. It's 18% at its steepest. The reward is a magnificent descent down Green Bluff Dr to George Rogers Park.
