Discovering the underwater world in Argelès-sur-Mer

Looking for a unique experience? To explore the seabed of our Mediterranean Sea?

Then don your wetsuit, put your mask over your eyes and let us guide you.

Why not take the plunge? Take a refreshing dip in one of Argelès-sur-Mer’s diving centers.

On the program: snorkeling (mask, fins and snorkel) and scuba diving (a baptism lasts around 25 minutes).

It’s an opportunity to take to the open sea and discover the Catalan coast. This activity is open to everyone aged 8 and over, provided they have no health problems.

Half a day sea excursion

Just take your swimsuit and towel. As for the rest, your diving club will provide you with everything you need: wetsuit, mask, fins, snorkel…and of course the diving equipment (stabilizing vest, air tank, regulator…).

For your first dive, here are a few recommendations.

 Safety instructions

Before you head out into the deep blue sea, you’ll need to be patient… You’ll be given a small booklet to help you review safety and environmental protection instructions. It’s important to preserve the seabed and protect species and biodiversity. To do this, you must not touch or remove any living creature (you’ll have plenty more to remember!). Underwater, you’re going to feel pressure, so you need to know the right gestures to decompress: just pinch your nose and blow gently. Your instructor will also teach you how to communicate.

Once you’ve mastered the theory, you put on your wetsuit, test your mask and fins, and off you go to the boat. The equipment is loaded, the divers for the day cling to the ropes, the ship splits the sea, leaving a long white wake. The landscape flies by as you pass off the Racou beach. The Vermeille coast takes shape, with Collioure and its 7th-century medieval royal fortress (one of the last still standing, along with the Château de Vincennes). Finally, you reach the diving spot: Cap Gros. Everyone gears up, and it’s time to slide into the water.


With the wetsuit, you can enjoy the activity to the full without any particular effort. You can observe underwater life as you move along the water’s surface. Your guide challenges you to spot a few fish. After a 1-hour stroll, it’s time to get ready to dive and discover the secrets of the deep sea.

 Your first breath underwater

Your instructor will suggest a few exercises for you to do (it’s up to you whether you dare or not). Practice removing water from the regulator, retrieving it or clearing water from the mask. Time passes too quickly, and you’d like to stay at the bottom of the water over and over again… But it’s already time to surface.

It’s with fish in your eyes that you return to port. An experience you won’t forget.


Posidonia is a species of aquatic flowering plant. It is not an algae. Posidonia plays a fundamental role in the coastal ecosystem for a number of reasons:
– it releases around 20 liters of oxygen per day for each m² of seagrass bed
– it is home to numerous species of fish
– it consolidates the seabed and protects beaches from erosion as its leaves wash up on the shore.

Posidonia is the lung of the Mediterranean, and to protect it, the Gulf of Lion Marine Park has installed buoys to prevent boats from mooring in the seagrass beds.
