The Agora is very close to Hove Railway Station and easily accessible by road from the A27 or from Brighton. There is a bus stop next to the station and local taxis can be called when required. On street parking is readily available close to the building with a disabled parking bay/drop-off point for wheelchair users to the rear of the building. You can download a map here.
Travelling by car from London (A23) or areas outside Brighton you can reach Hove via the A27. You will need to take the Hove exit. At the roundabout, take the 3rd exit into the King George VI Avenue (A2038). Take the 2nd left into Nevill Road (A2023). When you reach the Old Shoreham Road you should go straight across the lights into Sackville Road and turn left at Clarendon Road to reach Ellen Street. There will be plenty of pay and display parking on Ellen Street and nearby roads. Blue disabled badge holders can park for free. There is also a disabled bay at the rear of the Agora entrance.
