You kind of skipped over a bit of the best...us locals know that the Coast gets crowded after Newport...
Between Brookings and Gold Beach are some rather majestic headlands and day hikes, myself, I stay out of Gold Beach as it's kind of an old folks town but it does have a great bookstore.
North of Gold Beach is Port Orford, a small town with more than a few hippies transplanted from Norcal in the late 1960's. It's usually warmer in PO than anywhere else on the Coast because the beach itself faces south-out of our perpetual North wind summers. Battle Rock is there on the beach side as you come down the hill into town, worth a stop for the Indian Wars history. We also surf there a bit in the summer. Just south of Port Orford too is Humbug Mountain SP, its a great hike with a 360 degree view at the top that can't be beat. A bit north of PO is Cape Blanco, the western most point in the Continental US, 400 miles west of LA!
Next up is Bandon-see Gold Beach note.
Next you will trip through some woods and come up on Coos Bay, Charleston and North Bend.
Shore Acres State Park should not be missed if you are a fan of rare plants and flowers.
Charleston is the quintessential fishing town, a hard working harbor and enough characters to fill out a Steinbeck novel.
Sunset Bay is a great beach to stroll and there are paths from there to Cape Arago, where Drake took shelter in the 1500's. Last summer, we had three gray whale momma's and babies hanging out there.
Coos Bay itself...well, the glory days are long gone but I call it home.
I have a couch if you need one (check couchsurfing.com).
But we are the southern gateway to the Dunes (which can be a bit over run with the atv/4x4/dunebuggy crowd, you know, "tread violently"...)
Reedsport boasts the best skatepark on the Coast.
Florence? Thats 'sandnsea' country!
