Follow the old Chichester to Midhurst railway line through the South Downs landscape over the River Lavant, past a riverside play area to West Dean, where there is a village stores and tea room. A new extension means that you can press on even further to the beautifully restored platform at Singleton. There are a couple of worth-while attractions such as West Dean Gardens and The Weald and Downland Living Museum if you want to add to your day out.
