This is a near drive-up in a carefully driven Prius, or perhaps a full-on drive-up in a vehicle with some ground clearance.

Garwood Butte, OR | July 2021
Summit:
W7O/CS-036
If you are touring anywhere near Crater Lake National Park, Garwood Butte is a quiet destination for an activation. The forest road is fairly Priusable and the hike is reasonably short, even if a bit steep in places. As for a number of other summits, one reward for making it to the top is a historic fire lookout. The "upper" trailhead is about 1 mile and 600 feet of gain - from Forest Road 3703 (Three Lakes Rd) it's about 2.3 miles and 1000 feet.
From Roseburg, Oregon turn on OR-138 East / Northeast Diamond Lake Boulevard.

Sep 2023 Update: Buck Creek Road is closed a few miles from Highway 141 and so the shortest route to Monte Carlo described below isn't available just now. The longer routes appear to be acessable.
