Which state or national parks in CA have you visited? Which would you like to visit?
I'll start: I spent my 16th birthday at Joshua Tree, and since then have been to all seven of the designated national parks - Channel Islands, Death Valley, Sequoia, King's Canyon, Redwoods, Yosemite, and Lassen.
I'm working on the monuments and on the state parks, although I've visited quite a few. My current favorites are Leo Carrillo State Beach (where we try to camp every few years), Montana de Oro State Park, and Mt. San Jacinto State Park.
