Chugging between the mountains and the sea, the Train des Pignes is one of Provence’s most picturesque train rides. The 151km track between Nice and Digne-les-Bains rises to 1000m for breathtaking views as it passes through Haute-Provence’s scarcely populated backcountry.

The service runs four times a day and is ideal for a day trip inland. The beautiful medieval village of Entrevaux is just 1½ hours from Nice (return fare €24.40), perfect for a picnic and a wander through its historic centre and citadel.
