The highest point on the Oregon Coast is the headland at Cape Perpetua. There is a nice 2 mile trail from the visitor center to the observatory high atop the headland. This part of Oregon is exceptionally lush with lots of fern gullies and big old trees.
The view from the top is stunning, north to the town of Yachats, and south along the Cape Perpetua Coast that we hiked the day before.
We had a short visit, at the CCC built observatory, with some friends who were passing through the area, then hiked ourselves down the hill to make plans for the Fourth.
