We showed up here in early June with no reservations and had no problem getting a spot.

Oregon State Parks now charge a 25% surcharge for non-residents for RV / hookup sites.

Tent/non-hookup sites are only $22 (whether resident or no), and electric/water sites are  $35 for Oregon residents and $44 for non.  There are no sewer hookups here but there's a free dump and water fill at the entrance. There are water spigots throughout the campground.

The RV loops are more like your basic crammed in RV park sites, with all sites closely in a row.  The two tent loops, H and I, have a nicer feel, more spaced out, more trees, and quieter.  RVs are allowed to camp in tent sites, and no generators are allowed (yay!).  There is some tree cover but there are plenty of sites with enough open sky so you can use your solar panels easily.

Showers are really nice, and free.  They are set up in individual units, which I prefer.

The trails to the beach are nice, but were really swampy when we were here and the mosquitos were really aggressive (bit me through two layers of clothes!).

There's a cool disc golf course but we didn't get to play, mainly because of the mosquitos. 

Campground is close to the cute town of Newport.

Overall we liked it here.

ATT phone had good coverage.  Verizon was usable but weak, but the cell booster helped.
