I got a request for the locations and overviews of the stops Dana Hunter and I made on our rocking around Oregon a moth ago. Instead of locations, I've added FlashEarth links, which have detailed Lat-Long information attached to them. Additionally you can zoom in to surprising resolution, or out to get a better sense the where the spot is in relation to other things.
Note: Dana and I pointedly planned this trip to coincide with a series  of negative tides (those with low water elevations below the average of  the lower of the two daily low tides) specifically so we had good, safe  beach access, and a maximum extent of time to look at rocks exposed  there. DO NOT takes chances with the Pacific Ocean. It's anything but  "pacific," and it's very cold here in the PNW. Even the strongest and  healthiest have little time to survive if they unexpectedly find  themselves in the water and can't quickly get themselves out.
Day 1 (half day)
Stop 1, Yaquina Head- Columbia River Basalt  reached the location of modern coast in a number of spots. Yaquina Head  is one of them. Cobble Beach, a lovely beach of polished basalt cobbles  and tidepools, and Quarry Access, a well-intentioned, but poorly  geologically thought-out project to provide wheelchair access to  tidepools. The inevitable result, which I predicted correctly just a few  weeks after it opened and I visited it the first time, is reason enough  to go down to the "tidepools" here. Aside from the geology, the visitor  center is quite nice, and the views from the cliffs near the lighthouse  are epic.

Looking SE from lighthouse parking area, down onto Cobble Beach; Newport, OR in the distance.

Cobble Beach

Quarry Access "tidepools." An abandoned quarry was modified, pathways added, and opened to the ocean in hopes of creating a unique spot that allowed handicapped access to tidepool viewing. Unfortunately, I don't think any geotypes were involved. It was blatantly obvious from the outset that the site was an excellent sediment trap, and would not permit the high-energy wave environment necessary to create and maintain tidepools.

Stop 2, Beverly Beach State Park- Fossiliferous cliffs in Miocene Astoria fm- walk under highway bridge  from day parking then turn left (south). Mud/siltstone has scaphopods  that are difficult to collect; nicest fossils are in sandstone, past the  muddy cliff. Collecting (I just learned on this trip) is technically  illegal here. Sadly, I didn't see that until after we'd returned to the  car. Oh well.

Stop 3: Devil's Punchbowl State Park- 1st, drive to lot at end of  headland, for a nice view down into the namesake punch bowl. Then turn  around and drive the couple blocks or so to the beach access parking  between B and C Avenues. We went down the south cove, which was every  bit as awesome as I remembered- haven't been down there since late 80's.  North cove is a bit more of a walk (less so if you park in the overflow  parking off 2nd, west of C), but also has good geology exposed, plus,  if you go during a good tide, you can get an interior viewing of the  punchbowl. If you choose to do this, keep a very close eye on the  water... people have been trapped there. Don't recall anybody dying, but  it's scary and expensive. Yes, they pass as much of the cost on to the  rescued as they can.

Day 2:
Stop 1, Seal Rock- Quick stop for overview from terrace, didn't go down  to beach. Nice beach, but geologically there are more interesting  places. Major importance of this spot is that it's the southernmost spot  known where CRB reached the location of modern coast.

View to the north from top of elevated terrace at Seal Rock.

View to the south. Between these two views, you can see this is an "invasive" dike. A subaerial flow of CRB reached unconsolidated sediments at the Miocene Coast, then intruded down into them. This is not uncommon along the central to northern Oregon Coast, but it is a sort of odd situation; "intrusive lava" ought to be an oxymoron, but there it is. It was beginning to be suspected, during the 80's when I was an undergrad, that this was indeed the case, but by the time I finished up, it was only accepted firmly for some of the more northerly occurrences. At this point it seems to be accepted for most of the isolated, younger basalt headlands north of the Yachats Basalt headlands, which can be seen on the horizon in the distance in the second photo. (Also, to try to avoid confusion, the basement rock of the Coast Range is Siletz River Volcanics, sea floor and oceanic plateau basalt, and it shows up in some outcrops along the northern coast too, but it's older, Eocene, and shows typical oceanic basalt features such as brecciation and pillows.)
Stop  2: Coming down off headlands toward Florence, there are some pull-outs  with nice views out over the Dunes. Another quick stop to admire the  scenery and snap a few photos.

View to the south, coming down off Yachats Basalt headlands, looking south over the dunes.
Aborted stop, but nice and recommended: Honeyman State Park. In the  Oregon Dunes, wind-blown sand has blocked numerous streams, so there are numerous fresh-water lakes, which drain to the ocean only by  groundwater movement. Cleawox Lake at this park is a good example. The  forest here is also beautiful, and the dunes are some of the best I knew  of until I found Eel Creek... though at my age, I'm less thrilled than I  used to be at climbing up hundreds of feet of loose sand.
http://www.flashearth.com/?lat=43.929301&lon=-124.111111&z=14.2&r=0&src=mslStop 3: Oregon Dunes Overlook roadside rest area- Not the best place to  see Dunes, though my nephew had a blast running and falling down them  here when he was out a few years back. The outstanding thing to see here  is the various stages of succession from open sand, to grass, to low  shrubs, to larger shrubs and shore pines, to mature Douglasfir forest.  From the overlook viewpoint, you can see examples of each of the stages  from one spot, and see just how disorderly and patchy the process really is,  while at the same time, being able to clearly see the progression.  Perhaps the only thing missing is a clear example of forest being  swamped and killed by advancing dunes, starting the process anew. But  you can see that at the next stop...

Looking more or less south from dunes overlook: nice stand of isolated, mature Douglasfir.

Looking out toward coast, dunes overlook.
Stop 4: Eel Creek- Park at the day use area, which I'm pretty sure I  have in the cross-hairs. (The campground entrance is about a half mile  further to the north, and is a nice spot to stay with kids. On field  trips with HS students, we've stopped at other places and this can be a  convenient place to know about.) It's about a half mile walk in through  lush coastal forest, and you come out onto the open dunes rather  abruptly. DO take a moment to look around and note prominent  landmarks... it's easy to lose your bearings on open sand, especially if  you get out of view of the spot at which you came in. This location  features some of the nicest dunes I've seen in my life. The large dune  to the south of the trail's egress into the sand is relatively easy to  get up if you walk to its eastern end, then follow the ridge crest up.  From the top, the view to the south reveals coastal forest being overrun  by advancing sand, as well as seemingly endless ridges of it out into the  distance. Extremely mesmerizing and memorable.

View to the southeast of forest being killed by advancing dune- though as you can tell from the grasses established along that slipface, the process is sporadic, not a steady, gradual one.

View south. Note slumping of slip faces on dunes in mid-distance.

Sand saltating across the top of the dune. Yes, it was windy.
Stop  5: Shore Acres State Park- Coos Bay (the bay itself, not the town) lies on the axis of a progressively  folding syncline; younger beds are less steeply dipping than older  beds. The triplet of state parks along this section of coast are my  favorite Oregon coast locations- and I love the coast, so that's no  small compliment. Shore acres has numerous features to explore. You can  get to sea level in the south cove, but for the most part, I've been  content to simply explore the top of the terrace here. The elevated  terrace, incidentally, shows a noticeable increase in elevation from  north to south, from Sunset Bay to Shore Acres, to Cape Arago,  respectively. The views are breathtaking here; a shot taken near the  shelter house is the first photo I've preferred to blank, undistracting  gray as my desktop image. Cannon Ball Rock is covered with large  concretions, and there are some lovely examples of tafoni weathering on  the platform north of that. Looking down into the cove from that  platform at low tide, one can see several faults criss-crossing the new  wave-cut terrace. If you want to spend some time not doing geology, the  gardens are very nice. However, just strolling the path along the cliff  and enjoying the scenery can burn plenty of time too. This is the spot  to spend your time when the tide is still up; the other two are best  visited at low tide.

Large concretions give Cannonball Rock its name.

Stop  6: Simpson Reef overlook- Most people want to look at the seals and sea  lions that haul out on these offshore rocks. Geologists take one look  at that zigzag pattern and go "Ooh! Plunging syncline-anticline pair!"  Can't remember which is which right now... I'll look it up later.

Simpson Reef
Aborted  Stop, but highly recommended: Cape Arago- we were getting pressed for  time, and choosing between walking down yet another flight of stairs to  spend low tide at Cape Arago, or driving back North to Sunset Bay was a  no-brainer. Structurally though, and in terms of diverse geology, Cape  Arago is the gem of these three parks. Ideally, one should set aside two  low tides at this park, one for the south cove and one for the north cove- I don't  think the middle cove is safely accessible. North Cove: some great folds,  enormous cut-and-fill channels, some kewl sed structures. South Cove:  some 
excellent sed structures, coalified driftwood, hidden but  fairly easily inferrable fault. Good tidepools. The FlashEarth imagery  does a nice job of highlighting the erosion into criss-crossing faults  on the sandstone headland itself.
