Tunbridge Wells is a VERY popular commuter town in the south east. The train station is exceptionally busy during the week day rush hour and best avoided by travelers and tourists at these times! Weekends find it much quieter.
The town is only an hour by rail from central London (Charing Cross station) making it an excellent day trip. Hastings and Ashford International are also on the same line.
