Sadly Salters Steamers no longer run regular 'turn up and go' timetabled trips along the Thames. In 2022 they will only run services for pre-booked parties of 40 or more people in the summer on the Wallingford - Goring - Reading or Wallingford - Abingdon sections. From Oxford - Abingdon and Reading - Henley the minimum number is 30. Please do check the Salters Steamers website for full details of their services and fares
