If you feel like you've completely exhausted your San Francisco to-do list (believe me, it can happen quickly whether or not you actually live here), there's always the stairways. While searching through different lists of "off-the-beaten" things to do in the city, I came across the Filbert Steps. Filbert Steps is one of 8 different stairways that can be found throughout San Francisco (see more here: http://www.sftourismtips.com/stairways-of-san-francisco.html). Basically, due to the hilly nature of SF, there are going to be some opportunities for architects to use their creativity and construct beautiful steps that carry people from one street to another. The steps on Filbert Street is one such creation.
Filbert Steps, as indicated by the name, is located on Filbert Street perpendicular to Sansome Street. The really amazing thing about this stairway (as well as the other 7 in SF), is that it really does serve a purpose. Essentially, these steps allow direct access from the bottom of Sansom Street, to the top on Montgomery Street. And so they'll be TONS of people going through Filbert Steps each day, whether for commuting purposes, working out, or even for tourism...
...and the last part is definitely true because Filbert Steps is GORGEOUS! My girlfriend and I decided to venture out and explore the steps as part of our whirlwind tour through San Francisco's lesser-known landmarks. If you have any desire to come, I highly recommend you take public transportation, as parking can be REALLY bad. Filbert Steps is located close to the Pier/Union Square and so chances are you may have to pay. There are some free spots (free on weekends) next to the base of the steps, but they may be taken up.
Let me preface by saying that Filbert Steps is truly a workout, especially if you don't exercise. Because remember, you're climbing up one of the steeper hills in San Francisco. Especially during the first part near Sansome, you are going to be climbing very high. I'd tread slowly if you have a fear of heights because it may get gnarly. But, the view is WORTH IT. It's not even that you get a great view of the Bay. Once you are in the middle of Filbert Street, you can get a glimpse of all the beautiful gardens and greenery that residents on the hill maintain. Yep, people actually live on Filbert Street. It's pretty cool!
The end destination of Filbert Street is Montgomery Street, where Telegraph Hill begins. This is actually a really nice area both because Coit Tower is there and also because you might see some parrots (https://www.yelp.com/biz/the-parrots-of-telegraph-hill-san-francisco)!!!
Overall, I give Filbert Steps an "omg, I'd travel 2 hours for this" rating. It's such a tranquil and transformative experience, both mentally and physically. More often than not, this area will be very quiet. And so it's a great opportunity to work out those legs and enjoy the view that San Francisco has to offer!
Have fun and prosper,
