Glad you were able to get to Pinnacles NM. Amazing that they think those rocky spires are an old volcano that has slowly moved northwest from the Los Angeles area, riding the tectonic plate!
I've been going to Pinnacles since the 1940's. Used to be a lot more remote, at the end of a poorly-maintained road. Now I can't believe the agricultural development in the Salinas Valley....all that lettuce! And increasingly, grapes!
A couple of years ago my Finn wife and I hiked from the west side, up over to the main campground by the high trail, using all those stone steps and iron hand-holds. Then we hiked back through the caves to the west side. She'd never seen country like that in Europe! Still quite an adventure.
Thanks for sharing -- yes, an amazing place!
Our two hikes were probably shorter than yours but we did hit those stone steps, railings, and caves. Another example of CCC construction!
And kayaking Elkhorn Slough was our other trip highlight.
