In the south, the basin and the outer port shelter the Roc Headland, which is surmounted by the sharp steeple of the church, holding the lighthouse tower, placed side by side to a semaphore in its wing tip.
The black and red Loup Turret is situated south of the Roc Headland, in the selvage of a rocky plateau.

The outer port :
Accessible 2 hours 15 minutes after low tide.
Coefficient : 70
1.50 metre water draught.
The outer port can be a shelter except in case of an S.S.E wind.
The port entrance :
It is recognizable thanks to its two green and red markers delineating the drawgate, between which it is compulsory to sail. The gate remains open 3 to 3.30 hours depending on the tide coefficient, before or after high tide. A lighting signboard indicates the basin water draught. The displayed height of the water must be confirmed by the reading of the depth gauges.
By night :
The port entrance is marked by a red and green traffic light flashing every 4 seconds.
The gate of the port is delineated by two red and green traffic lights fading every 4 seconds.
Five blue traffic lights flashing every 4 seconds indicate the submersible dyke perches of the practise area. Lighting boundary markers light up the inner basin pontoons.

- Practise basin perches

- Lighting signboard of the gate
The practise area perches delineate the submersible seawall (the seawall can be sailed over by subtracting 70 centimetres to the indications written on the lighting signboards).
The lighting signboards indicate the water height. They are located over the threshold of the gate.
