A little nature and some great views!
Presidio Park, part of the Golden Gate National Recreation Area, is a stretch of park, woods, and trails which stretches from Pacific Ave. down the hill between the Golden Gate Bridge and the Marina. It's a cool place to go for a morning stroll, enjoying the views of the bay and picturesque streets only found in San Francisco.
I'd suggest taking a stroll from Alta Plaza along Pacific Ave., checking out the astonishing mansions and interesting little corners what wind down the hill, then follos the paths in Presidio Park until you hit the main road. Just follow that road down the hill and
