W7O/NC-113 (“good ‘ol 1783” as they say) is a small coastal peak in USFS Siuslaw Forest land. From Hwy 101 take the turnout at (45.065829, -123.948579) — Google calls it “Cascade Head Trail - North Trailhead” as it’s the road that leads to the trailhead. This is forest road NF-1861 and is nicely graveled and easy to drive with a passenger vehicle.
Note: this road is closed by the USFS from Jan 1st to July 15th, effectively making this summit inaccessible during that time.
