I suggest you read what is written on the website, and, if you don't trust what you read, email (or call if you can locate a number), and ask?!

Nosotros subimos caminando hasta la Coit Towe pasando por el barrio italiano y de ahí nos fuimos al Fishman's Pier... yo te recomiendo que, si no vas con nadie mayor o muy pequeño, te vayas caminando hasta ella... descubrirás barrios hermosos y vistas aún mejores.

Don't think I can help you because my husband and I seen the tower from the road and wondered what it was. We walked up the hill (very steep) and paid at the entrance which is just inside the door. There was no queues and no time slots. We just "rocked up" and went in. After seeing this place I am so glad we did NOT get this on any tour. I don't think it's worth that. You are only in there for an hour at the most. It's nothing too special but it is informative of a piece of San Francisco's history.

The only way is the elevator . But if you want steps, you could walk up the 483 steps from Filbert to get to the tower itself! We did it and we are 60+ . And yes, we were happy to see the elevator inside. They also give a senior discount $5.00.
