I’d like to hit the coast in Yachats and do several mostly-quick viewing stops to see the sea lion caves, Blacklivk Point, Cape Blanco Lighthouse, am not sure how far down to go (is Crescent City worth backtracking for?), then get on 199 through Grants Pass and see Crater Lake and maybe see a great water fall somewhere.
Is this doable?
Is there a waterfall you would recommend somewhere not far from this route?
What would be the best place to stop for the night (value and availability more important than night-life and scenery)? Is Grants Pass too far to go at the end of day 1?
