We came in from the north on Hwy 101, and Waze wanted us to turn at Manzanita, just north of Nehalem, to get to the state park. It was a sharp and weird angled turn, so we pressed on a couple of miles, where there was a state park sign. We followed the signs to the park and campground(CG). No one was at the check-in booth, but instructions were to proceed to the registration kiosk in the A loop. We registered and headed for back-in Site C-26; 50 amp& water. Our three-day stay was free as we have the Oregon Disabled Veteran's Pass. As we went through the B section, we had to be very careful on this Friday after Thanksgiving, as the CG looked like a summer holiday weekend with vehicles parked willy-nilly near or on the road. We noticed and were told by other campers that Oregonians love to camp this time of year in large friend and family groups. This had been the case in the last three State Parks we’ve camped in. We got to the C section, which was not quite as busy, and proceeded to back into our site. The camper across from us gladly moved his truck so we could maneuver into the asphalt pad more easily. We had pine tree branches overhead, and we did our best not to scrape, but one branch lightly scraped an air conditioner cover on our 13.5-foot 5th wheel. The pad was long enough for our 5th wheel, and we parked our F450 at a slight angle to stay off the road. The water and electric hookups were at the back of the pad, so we needed 25’ of electric cord. One side of the road(outer sites) has angled sites, and the other(inside sites) has 90-degree back-ins. Whether even or odd sites depends on how the loop sites flow into one another. For example, our site C-26(outer site) is angled. In the D loop, site 41, which is a nice site for a bigger rig, is angled versus the even sites across the road, which are 90-degree back-ins. We had a fairly clear shot for our Starlink and three bars on Verizon. There was beach access from our loop, and we enjoyed walking our dogs on the multiple trails in this state park. The reservable loops were full this Thanksgiving weekend. This time of year, the D, E, and F loops were first-come-first-serve and nowhere near full. If we had known this, we would have gone to this less crowded area.
