All Regatta traffic and all Trailers should access Hillside Car Park via Remenham Church Lane and Aston off the A4130 (i.e. the TOP of Remenham Hill)
Exit from Hillside Car park on Friday & Saturday will be from the lower gate opposite Upper Thames Rowing Club, turning left (south) along Remenham Lane to Henley Bridge.
This will greatly help the flow of traffic to and away from the Regatta and will avoid potential clashes of trailers & other vehicles on the narrow roads leading to the Regatta.
