One of my favorite places in San Francisco is Twin Peaks.
These are two large hills in the middle of the city. You can hike, drive or bicycle to the top of the peaks. I drove up and parked on the side near the top. Yay for free parking. Once you get out, you need to climb for about 5 or so minutes on man made stairs to reach the top. The view from the top is breath taking. You can see the beautiful city, golden gate bridge and the ocean. I was hoping to go there one day during sun rise, but never quite made it. Saving it for next time!
