Ahh, Pinnacles. The nation’s newest national park, signed in 2013. Gee, thanks Obama! Honestly, very few people outside of climbers and hikers have ever even heard of it, and it’s the closest national park to the Bay Area.
The park itself has a fairly interesting geographic history, well worth a read. There’s a plethora of volcanic formations to scramble over, but mind the rattlesnakes. There’s also a concoction of eagles, raptors, condors, and bats to keep you busy. Oh, and caves. Don’t forget the caves!
