L'Arche du Moulon

Best time to dive

May to October

What you might see

• Flamboyant cuttlefishReliably seen
• NudibranchReliably seen

Sightings are seasonal probabilities, not promises - even in peak season nature does its own thing.

Certification & difficulty

Advanced Open Water - advanced conditions (currents/depth); dive within your training.

Snorkelling

Not a snorkel site - Limited viability - the shallow arch at 10-12m is beyond casual snorkeling depth though visible from the surface in calm, clear conditions; the site is primarily a boat-accessed scuba dive rather than a snorkel spot

Safety notes

Depth extends beyond common recreational limits at the drop-off (28-33m); boat traffic near the Niolon/Cote Bleue coast; mistral-driven sea conditions can affect access

Permits & fees

No specific paid diving permit or fee was found; the site lies within the Parc Marin de la Cote Bleue marine protected area, where general rules apply (no removal of marine life, respect of protected habitats)

Permits and operators change - confirm before booking.
