Six Ideas for Day Trips

Gourdon - Tourettes sur Loup - Saint Paul de Vence and the Fondation Maeght. 

Great circuit and ends with a world class museum with views to the sea.

Head south to the sea with a stop in Mougins and then enjoy lunch on the water in one of serveral coastal cities.  Check out the Musée Picasso in Antibes or the archaeology museum in Cannes.

Drive along the coast from Manelieu to Agay for stops in private beaches and add in some vineyard visits around La Motte (Château d'Esclans  or Château Sainte Roseline)

Barcelona and Paris combined into one city.  A full day of things to do.  There are so many markets in Nice. https://www.seenice.com/markets/

Great dining and museums from Matisse to Chagall:

The seaside clifftop town of Eze and on to Monte Carlo and Menton. In Monte Carlo I like the Private Cars Collection of HSH Prince of Monaco and the Musée océanographique.

A long road trip but worth it if you want to see classic Provence France. Anchor in the town of Aix-en-Provence. For picturesque villages in the Luberon region, explore Lourmarin, Ansouis, or Cucuron, all offering a glimpse into rural Provençal life.
