Taxis

For reasons of safety, congestion and to try and avoid disruption to our local residents, we are working with local taxi companies to offer drop off and collection from our designated Taxi Point, located at the Tower Gardens Car Park around 200m from the Festival site. Continuing west from the traffic lights at Admiral's Park north entrance (junction Rainsford Road and Park Avenue) pass the Black Bull pub and in 200m you will see the Tower Gardens car park to your left. Please use the designated drop off point if you are booking a taxi. We will be providing clear signposts to assist you.
