This car park is well located beneath the Tunsgate Shopping Centre in the heart of Guildford High Street.
Often there is a queue to get in and once you are in the queue there is no way to get out of it if somebody comes in behind you. The queue is usually not more than about 15 minutes though.
Tip: if the queue extends back past the car park exit you may do better by turning around and going up to Castle Car Park.
