Flying Fish Tours
For an on-the-water perspective from the Thames, book a one-hour speedboat trip with Flying Fish Tours. The high-speed excursion takes off from St Katharine Docks (just east of the Tower of London and the Tower Bridge), then zips through sections of the Thames where speed is unregulated. The tour also includes London sightseeing, with some under-bridge jaunts. Since 2007, this tour company has offered several package options, including basic and extra-scenic tours, as well as private rentals for special events.
