I traveled north from Florence OR to Newport. It's about the most spectacular coastline in the Pacific Northwest. Below are the astounding sites I saw:
Roadside Viewpoint between Florence and Sea Lion Caves
As the road climbs from sea level up toward Heceta Head, there's a wondrous viewpoint (or three) on the west side of the road, overlooking the ocean and Lily Lake below.
Heceta Lighthouse and Sealion Beach Vantage Point--I could have watched this scene practically all day, except there are still so many other exceptional things to see! I made a slide show so you can look at one or many pics (to see the subtle differences in the waves)--out of 46 shots, I got it down to 7-8, with great difficulty.
Heceta Head Lighthouse & State Scenic Viewpoint
Vault toilets & porta potties, limited picnic tables. Hike, picnic, fish, spend some time at the beach.
I ran out of camera battery for this, but below is one photo and some info about
Muriel O. Ponsler Memorial State Scenic Viewpoint
Tokatee Klootchman State Wayside/Natural Site
Apparently Tenmile is a good place to hunt for agates.
This is another Pacific place so pleasant to picnic, ponder, or just sit and watch the ocean in wonder, it's hard to leave. I took a lot of photos, but made myself narrow them down for this post.
Strawberry Hill Wayside
Neptune State Scenic Viewpoint & Neptune Beach South
Cook’s Chasm & Thor's Well
Another place so fascinating along the Oregon coast you can hardly drag yourself away . . . wheelchair accessible in part: views from the bridge above are wondrous.
Cape Perpetua Visitor Center
Cape Perpetua continued--Lookout (Overlook, Campground) & Cape Cove Trailhead
Seal Rock/Seal Rock State Recreation Site--between Waldport and Newport OR
Ona Beach/Brian Booth State Park—8 mi south of Newport OR
Lost Creek State Park--7 mi south of Newport OR
From their website it doesn't look like it has wheelchair accessibility.
I've been in a wheelchair for 30+ years. It poses some challenges for traveling. Maybe others can benefit from my experiences.
