Enjoy breakfast with your family on the terrace of Le Prieuré and set off for an educational discovery of the papal charterhouse. A giant touchscreen there gives you access to its historical and artistic archives. If you reserve your picnic basket the day before at Le Prieuré, you can enjoy it among the scrubland of the Mourgues hillside before visiting the city's planetarium. You might finish the day at Fort Saint André. On Mondays in July, and on Mondays and Wednesdays in August, enjoy a guided tour at nightfall with a tour guide.'
