Ô Sea Bleu Dive Center

The centre is at Saint Gilles les Bains marina. Most of our dive sites are located in a marine nature reserve and are accessible to all types of divers. This means you can dive amongst abundant marine wildlife and plants.

The centre is open daily from 7am to 5pm with two daily meeting times:



Who are we?

Ô Sea Bleu is a professional centre. This means we are obliged to employ only qualified instructors. They make sure every trip is rigorously monitored and as comfortable as possible and they know the sites and how best to dive there. We provide regularly renewed and maintained equipment in partnership with Aqualung.
The Reunion Island tourism committee supports us and has awarded us a Réunion Qualité Tourisme label.


Three comfortable boats (12, 18 and 21 seats) take you to our dive sites.
We organize 2 to 3 trips every day of the week (see next trips – in french). We can schedule your trips according to your availability as well as your preferred sites and times (10 days in advance).
For groups of 6 people and more it is possible to hire a private boat and take trips to whichever sites you want at whatever time suits you.
From beginners to seasoned divers all types of dives are possible and available throughout the year as the water temperature ranges from 22°C in winter to 29°C in summer.
On the way to the sites it is not uncommon to come across dolphins, porpoises and whales (from August to October), which will not fail to leave a lasting impression.


In partnership with Scubapro, we renew our equipment regularly to make sure it is as reliable as possible.
We have equipment suitable for children as well as a large choice of wetsuits (shorty and full length) to fit men and women.
For scuba divers we have 10L, 12L and 15L 230 bar cylinders for air or Nitrox, computers and safety balloons. We have everything you could possibly want. The fill station has bottles with stoppers which means that filling is quiet.

ANMP (National Association of Diving Instructors) is a professional organisation, with trade union status, which consists mainly of professional diving instructors or future instructors.
Faithful to the spirit of “Plongée Française” (French Diving), ANMP works towards the future of quality diving, which respects divers and the environment. Its training courses give divers the necessary required skills while keeping the activity playful; let’s not forget that the technique is not a goal, just a way of safely appreciating the wonders to be found in the sea every day.



A whale watching in Reunion label.
Since 2009, on the joint initiative of SYPRAL (Professional Union of Leisure Activities) and the Globice association (Local Whales Study and Identification Group), a charter about approaching and observing humpback whales has been produced.
This charter outlines the rules of good conduct aimed at containing any disturbance caused to whales, while enjoying the spectacle of nature with a mutual respect for the users of the sea.



The term “NITROX” comes from the contraction of the words NITRogen and OXygen.
Nitrox diving takes place with oxygen-enriched air (O2) which has less nitrogen (N2), also known as EAN for enriched air nitrox.
The interest of these dives lies in reducing the amount of nitrogen to:

  • make dives safer by reducing the risk of decompression sickness.
  • reduce tiredness at the end of a dive, due in large part to eliminating excess nitrogen.

Nitrox can be used either during the entire dive, or during the decompression phase only after diving with air or trimix (nitrogen, helium and oxygen).
