La Passe Flic en Flac is situated in the channel (passe) that cuts through the fringing reef off Flic en Flac, one of the most popular beach resorts on Mauritius' western coastline. As the name suggests, this is a pass or channel dive — a style of diving that takes full advantage of tidal and oceanic currents moving water between the lagoon and the open Indian Ocean. The site sits roughly 1 to 2 kilometres offshore from the Flic en Flac beachfront, and is accessible by short boat ride from the many dive centres operating in this busy resort area.
The topography here is defined by the natural cut in the barrier reef. On both sides of the channel, coral buttresses and walls drop away to sandy floors at depths ranging from around 15 metres to over 25 metres on the outer slope. The sandy channel floor itself provides a stark contrast to the colourful coral structures flanking it, and is a favourite resting spot for rays and flatfish. Whether you drift through the pass or explore the coral walls at your own pace, La Passe offers something for divers of every style.
The nutrient-rich currents that push through the channel make La Passe Flic en Flac one of the most biologically productive dives in the region. Expect to encounter a wide variety of marine species on any given dive:
Turtle sightings are also common at this site, particularly green turtles that graze on the seagrass and algae along the channel edges.
Conditions at La Passe Flic en Flac can vary considerably depending on the state of the tide and ocean swell. When the current is running, this becomes an exhilarating drift dive that carries you effortlessly along the channel. At slack water, the site is calm and suitable for more methodical exploration. Visibility is typically excellent on the west coast, often reaching 20 to 30 metres in good conditions, particularly during the dry season months.
The site is best suited to intermediate and experienced divers due to the potential for current. Beginners should attempt this dive with an experienced guide and only under calm, low-current conditions. Surge can also be present when ocean swells are active, so always check conditions with your local dive centre before heading out.
The west coast of Mauritius is sheltered from the dominant south-easterly trade winds, making it diveable for most of the year. The best conditions are generally found between May and December, when the dry season brings calmer seas, excellent visibility, and comfortable water temperatures. The water temperature ranges from around 24°C in winter (June–August) to 28–29°C in summer (December–February). During the summer months, tropical storms can occasionally affect visibility and sea state, but diving is usually still possible.
