I camped twice at Cape Lookout this season - in June in a yurt, and in July at the campsite right behind the dune.  

In June, it was freezing, rainy and windy, and the yurt was fantastic. The most amazing feature of the yurt was the heater. It really kept the place warm, and the yurt was spacious. We were 3 adults, and could easily have slept another one or two. Each yurt has a small patio as well as a fire ring- and inside was electricity and a power outlet. Best of all, you were still just steps away from the sunset on the beach.

For camping, there are so many different kinds of sites at Cape Lookout - Sites closer to the entrance are very woodsy, the sites closest to the beach frontage (behind the dune) are very very open, and sites along the furthest perimeter are a little more spacious and some have trees (important to note if you want to hand a line or a hammock!)

We camped at the site right behind the dune where the beach access is. It was a little noisy since everyone passed our site on the way to the beach, but very lovely to be just steps away. Each of the tent sites has a fire ring and picnic table. In both June and July when I visited there was no fire ban.

Hiking is great in the area. You're also close to Pacific City, Jacobson's Salt, the tunnel at the Oceanside Beach, and Tillamook if you're staying here longer and want to take day trips outside of the State Park.

Recommend booking early for summer campsites. The yurt I booked in June was available for booking same day.
