Dana 17. lipnja 1903., manje od sat vremena nakon što je napustio luku Marseille za Bastiju, Otočni se zabio u desni pramac, vrativši se iz Toulona s četrdesetak putnika na brodu i pripremajući se za ulazak na imanje u blizini Ile Maïrea.

Situated to the south-west of Île Maïre, the cave has two main entrances at depths of between 12 and 9 metres, followed by a gentle drop to a depth of 25 metres.

To the west of Tiboulen de Maïre, a cove sheltered from the easterly wind. A drop-off of up to 25 metres with boulders between 16 and 20 metres and a tunnel accessible only in calm seas between 8 and 4 metres.

small cove created by the 2 islands, maximum depth 12 m. Mini passes between the 2 islands to get to the other side where there is a pretty little niche and a small platform between 3 and 8 metres. This continues on the left through a small canyon and a drop-off to a maximum depth of 25 metres.

The cave itself is a tunnel that opens at 12 metres, at the bottom of the canyon on the right. If you look up very quickly, you will see a well into which you can climb to come out into the open air, in a basin surrounded by glistening rocks. When the weather is fine, the lighting is magical.

Mali stjenoviti otok smješten južno od Marseillea, u blizini masiva Calanques. Dio je arhipelaga Riou, prekrasnog kanjona nakon kojeg slijedi iskrcaj. Nije neuobičajeno vidjeti škarpine, veće vilice, jegulje, anthias, dame, pa čak i barrakude.

Razne stijene do 15m, kao i plato sa stjenovitim oblucima i prekrasnim lukom! Zidovi su prekriveni anemonama i koraljima, a tu je i vrtoglavi pad, pravi zid i podvodna planina.

Also known as Pouars or Port de Plane, this well-protected cove resembles a small port. Left-hand rock, access only possible in calm seas to a small tunnel passing outside the cove between 4 and 8 m. Outside, two rocky peaks at around 12 m and a ridge at 20 m dropping to a maximum of 35 m.

Prekrasna padajući na maksimalnoj dubini od 40 m s malim platoom oko 30 metara, ova ogromna špiljska katedrala počinje od 25 do otprilike 14 metara i kreće se desetak metara unutra. ​

A beautiful drop to a maximum of 40 m with a small plateau at around 30 m, this enormous cathedral-cave starts at 25 m and drops to around 14 m, advancing by around ten metres on the inside.
