Please, please use public transport. There is limited parking around the Green and most of that’ll be used by the 120 stall-holders that attend the Fete. Also note the area is within the ULEZ.
Kew Fete is within easy walking distance of Kew Gardens Station (District line and London Overground) and Kew Bridge Station (London Overground).
Buses that stop on the Green are the 65 and 110 and the 237 and 267 buses stop a short walk on the other side of Kew Bridge.
To plan your journey use the planner on Transport for London’s website and use the postcode TW9 3AP as your destination.
