River Bus Travel
One legacy of the 2012 Olympics was a new push to develop river travel as part of London's overall public transportation system. The service, operated by Thames Clippers, stops at eight piers between London Eye/Waterloo and Greenwich, with peak-time extensions to Putney in the west and Woolwich Arsenal in the east. The Waterloo–Woolwich commuter service runs 7 am–11:05 pm on weekdays, 9:45 am–11:40 pm on weekends (peak-time frequency: every 20 minutes). Tickets are £7.30, with a one-third discount for Travelcard holders and a 20% discount for Oyster card holders. When there are events at the O2 (North Greenwich Arena), a half-hourly express service runs to and from Waterloo starting three hours before the event. Thames Clippers also operate the special Tate to Tate Boat, a 15-minute trip between Tate Modern and Tate Britain that costs £8.70 one-way. Boats run every 20–30 minutes, from 10 to 4 on weekdays and 9 to 7 on weekends. A River Roamer ticket (from £17.80 per day if booked online) offers unlimited river travel after 9 am.
