The company has been operating bus tours in San Francisco since 1997, and in 2005 took on the “City Sightseeing” brand, and imported San Francisco’s first open-top double-decker buses from London. Today, City Sightseeing San Francisco is the largest sightseeing operator in San Francisco, carrying almost 1.5 million passengers in the last 5 years, with a fleet of 20 open-top vehicles, as well as minibuses and vans.
San Francisco has several tour bus companies as you might suspect including City Sightseeing, Big Bus and Tower Tours. None of them are wheelchair accessible or ADA compliant. On their websites (and voice mail messages) they say they need 48 hours notice to arrange alternative transportation but this is non-sense. Their buses are not accessible unless you can walk up the steps. While SF and California pride themselves on being ADA compliant, their accessible tour bus industry is non-existent.
