There is plenty of parking on site at Dorney lake, however, the walk from the car park to the main event area is around 15 minutes, please take this into consideration when planning your journey.
The main stations are Slough (Elizabeth line from Paddington), and Windsor & Eton Riverside (from Waterloo). Additional nearby stations include Burnham, Taplow, Maidenhead and Windsor & Eton Central, all within a 15-minute drive of Dorney Lake.
