Henley Royal Regatta runs from Wednesday 3 July to Sunday 7 July during which there will be a towpath diversion.
The Royal Barge Gloriana, which was an attraction at the regatta last year, will be back in Henley on Monday 1 July.
In the morning the barge will travel upstream from Henley to the nearby River & Rowing Museum carrying again the cauldron used last year from Hampton Court to London.
The cauldron has been donated to the museum and Sir Matthew Pinsent, as a museum vice-president, will formally accept the gift.
