Took the cable car from the piers to downtown. Excellent experience. Tickets can be purchased onboard for 8$ per person per trip. Online passes available. Would have loved to get one. However....muni app failed miserably! It doesn’t accept foreign credit cards as payment. Cash payments for the pass only available at the main office and are 10$ a person more expensive. Major disappointment. Other than that. It was very fun and a must for travelers of all ages. The cars are very loud, so don’t expect to do a lot of talking.
