The best time to go to Fontaine-De-Vaucluse is during late spring (May-June) or early autumn (September-October) for pleasant weather and fewer crowds.During late spring, the weather is typically warm and sunny, with average temperatures in the low 20s Celsius. The famous spring that feeds the Sorgue River is usually at its most impressive during this period due to snowmelt from the surrounding mountains, offering a spectacular sight. It's also a wonderful time to enjoy outdoor activities like kayaking on the river or exploring the local walking trails, such as those leading up to the Château de Fontaine-de-Vaucluse ruins.Early autumn also offers beautiful weather, with comfortable temperatures, generally in the high teens or low 20s Celsius, and the summer crowds have largely dispersed. This makes it an ideal time for couples looking for a more relaxed and intimate experience. You can enjoy strolls along the riverbanks, browse the local artisan shops, or dine at the riverside restaurants without the peak season bustle.
