Brighton's biggest music festival, Boundary is held at Stanmer Park, halfway between the wilderness of the South Downs countryside and the city, with a lineup of international DJs, live acts and jazz bands, four stages, a vintage fair, local food and capacity for up to 20,000. Car parking is not allowed at Stanmer Village, but festival goers can park-and-ride from the Brighton's racecourse. By train, head to Brighton's main station, and jump on the 25 bus from Churchill Square.
