Are you planning on driving Ave. of the Giants, CA 254? There is lots of turnouts that you can pull off and walk in the trees. And when you look up at those giants it is awe-inspiring. Stop by the Humbolt Redwoods State Park Visitor Center https://humboldtredwoods.org/visitor-center (might be closed, Covid) and spend couple hours. I seem to remember a few parking spots along the road and a couple nearby that you could walk back to it.
The road is narrow, curves around trees that are right next to the road (and they show battle scars) but it can be done. And worth the drive.
Weren't you asking about Salem and Crater Lake? If you have the time head to Gold Beach, OR and take a fun ride on the jet boats. You will have a blast and you will get wet and you will want to do it again. https://www.roguejets.com/ Take at lest the 80 mile trip. The meal stops have decent food and the prices won't break the bank. The parking lot at Jerry's should accommodate you, but ask.
We stay at Kimball Creek a few miles up river, the boats stop there with reservations. http://www.kimballcreek.com/
Word of caution. If someone tells you to take the road (name skips my mind) from Galice to Gold Beach, DON'T. Way to easy to get lost up there and the road isn't suitable for your rig. Most maps and GPS don't show it as an option any longer.
