On the central coast you'll find the town of Newport. Located there is one of the best aquariums on the west coast. Newport is also home to the NOAA west coast HQ, two light houses, a working bay front full of shops, fabulous restaurants and let's not forget the Pacific Shores Motorcoach Resort that is a 5-star Good Sam rated 10-10-10 resort...easily the foremost rv resort on the coast. You can get that morning's fish/crab catch at just about any restaurant and with all due respect to Ed Gee's statement, we've found the best halibut fish & chips at the South Beach Fish Market just over the Yaquina Bay bridge. The best clam chowder in Newport can be found at the Chowder Bowl on Nye Beach. In addition to all of that, Newport is home to the Rogue Brewery that provides tours, souvenirs, and two great restaurants...one at the brewery and another on the bay front.
If the Pacific Shores Motorcoach Resort is full, there is also two state campgrounds (Beverly Beach and South Beach) in addition to the Marina RV Part.
Being mid way on the coast, Newport is the logical place for a stop over.
