This is the most memorable place I've visited while staying in SF. Go here towards the end of your stay, after doing all the touristy stuff, this will feel like a spa retreat. The air is so fresh, because of the forest, the smell is a mixture of trees and ocean, so delicious. Just walk around, if you are lucky you'll see people climbing trees, its kinda impressive. Otherwise, just go straight to the ruins. If its a sunny day you'll see ocean, birds and beautiful rocks. If its a misty day just find yourself a place to sit and daydream. The whole place looks so dreamy and mysterious! Dont forget to explore the cave on your right side. Take some sandwiches with you, it's a nice place to have picnic. You can also walk through lands end to the Legion of Honor, a gorgeous museum.
Just don't forget your camera, you can take incredible shots there!
