And more to come …


By offering artificial nurseries of the '' Biohût '' type to fish, we have rebuilt Port Fréjus into a habitat area belonging to them to allow them to reach adulthood.

Every day, we ensure that their growth takes place in the best conditions by inviting our boaters to preserve the quality of the water in our port.

But faced with the capital issue of respecting marine biodiversity, we will never do enough, and we were therefore eager to do more.

This is how the idea of creating A LAND TRAIL & A TRAIL UNDER THE SEA was born with the aim of explaining why the preservation of our marine environment is vital to us.
We have called these trails “Les trails du Mérou” .

Thanks to these trails we hope to put the keys in your hands to ensure respect for the marine environment that surrounds us, and which is essential to our survival.


This TERRESTRIAL TRAIL will lead you to the various modules installed on the quays of Port Fréjus. These modules, all on a different theme but linked to the preservation of the marine environment, are positioned to have fun and inform you while strolling through Port Fréjus.

Port Fréjus is an inno (vi) port, committed and fervent defender of the environment, which wishes to transmit its values to you by offering you these two paths.

We wish you a pleasant time on our land trail of Mérou and also invite you to dive soon with mask and snorkel to discover our TRAIL UNDER THE SEA . (installation planned for 2022)

Welcome to Port Fréjus. Welcome to the fish habitat area, and have a good walk on our hiking trails and under the sea.
