The Festival Theatre is on Nicolson Street, which is the continuation of North Bridge heading south from Princes Street. Please note there is limited street parking around the Festival Theatre. There is a small car park located about 5 minutes walk from the theatre on Niddry Street (7am - 11pm, 7 days).
If you wish to cycle, there are bike racks in front of the theatre as well as on the side (by Stage Door). You can plan your cycle route using one of the different interactive routes available on the Edinburgh Council's website, including a QuietRoutes planner.
