When to visit Saint-Marcel Cave?

Summer (July-August): busy but cave’s 14°C is heavenly during heatwaves.

Off-season (September-October): our favourite. Few people, intimate visit, even more magical lighting. Closed Tuesday in September. For an off-season group weekend, the perfect tour — when Mas Saint Antoine offers the most availability for property privatisation.

  3. Wearing flip-flops: closed shoes required.
  4. Arriving at last minute: last tour 1 hour before closing.
