Cape Kiwanda State Natural Area is a deservedly popular reserve on the north side of the ocean beach at Pacific City, Oregon. It features a fascinatingly sculpted rocky headland with both basaltic (lava flow) and sandstone components, a tall sand dune beloved of hang-gliders, the flat beach where Pacific City's dory boats launch and land, and a spectacular sea stack offshore. Cape Kiwanda is one of the features for which the Three Capes Loop is named.
Circa 2012, I visited with family in the off-season. The weather was iffy, and we parked at the Pelican Pub & Brewery for a great meal and brews, then walked up the dune to explore the fantastical geological formations with a few other visitors.
I visited again on the 4th of July weekend in 2019, and the place was so packed that we just drove past. There isn't as much parking as this popular spot needs. There was a lot of new development in the area since my last visit.
Be aware that there are fatalities here every few years as people fall from the unreliable, crumbly sandstone cliff-tops.
