Abbaye de Senanque, Provence - Billions of these tiny purple-blue flowers grow in great swaths in the corner of the Cote d’Azur and Provence in June, July, and August. There will be festivals celebrating the season and markets to distract you. Walk the easy 2.5 miles down from the medieval village from Gordes to the Abbaye de Senanque.
