Roches Noires is the beach most visitors to the west coast meet first, the broad central strand of Saint Gilles les Bains, and its character is all about the town it belongs to. This is the lively, sociable, convenient beach, a generous arc of pale sand studded with the dark volcanic rocks that name it, with the resort, the marina, the bars and the restaurants pressed right up behind the front. By day it has the energy of a surf and bodyboard crowd, by night the seafront lights up into the busiest evening scene on the island. As a piece of resort beach it works hard and it photographs well in the low light.
The honest read is that Roches Noires is an open coast beach, not a lagoon, and the swimming has to be understood through that. Because the water here is more open than the reef sheltered lagoons just south, the beach carries an anti shark net that encloses a supervised bathing zone, and that net is the whole story of swimming. You swim inside it only, during the posted cover hours, and because it depends on conditions it can be removed or closed when the swell turns up. This is also where the island's shark crisis announced itself years ago, which is exactly why the secured zone and the rules exist, and why we treat the open sea here as closed.
So our verdict is to come to Roches Noires for what it does best, the town life, the surf watching and the sociable seafront evening, and to take the swim as a flagged bonus rather than the main event. Check the net and the flags, swim inside the zone during cover hours when the sea is calm, and if you have small children or simply want a gentle certain swim, drive the few minutes south to the calm reef lagoon of L'Hermitage. Read it that way, the buzzing town beach for the day and the evening, the lagoon for the family swim, and Roches Noires earns its central place without catching you out.
Roches Noires is a free public town beach backed by the Saint Gilles seafront rather than a daybed club. We describe it honestly and route enquiries through our directory, never inventing fees or amenities.
The Roches Noires beach life is the Saint Gilles seafront of cafes, bars and restaurants and the marina just along, the busiest going out scene on the island, rather than a reserved daybed venue. Verdict: the most sociable and central beachfront on the west coast for a flagged swim, a surf watch and a long lively evening, mostly pay as you order, with opening hours and any minimum spend to be confirmed by the venue.
Roches Noires sits in the centre of Saint Gilles les Bains on the west coast, about an hour from the airport at Saint Denis and signed straight to the seafront and the marina, with town parking nearby. It is minutes from the L'Hermitage and La Saline lagoons just south, so the calm reef beaches pair easily with a town day here, and a hire car is much the easiest way to move along the west coast.
Before you plan a swim, check whether the net is in place and read the flags, and swim inside the netted zone only during the posted cover hours when the sea is calm. Arrive early on fine weekends for parking and a spot on the sand, carry small cash for the seafront cafes and bars, and bring sun cover as the open beach has little natural shade. Never swim outside the netted, supervised zone, follow the lifeguard guidance, and keep small children close.

Only inside the netted bathing zone during cover hours, and that is the key fact. Because the beach faces more open water than the lagoons just south, it carries an anti shark net enclosing a supervised swimming area. You swim inside that net only, when it is in place and the beach is supervised, and it can be removed or closed in strong swell, so swimming is sometimes suspended. Follow the lifeguard flags and signs without exception and treat the open sea as closed.
Yes. Roches Noires has an anti shark net that encloses a marked bathing area, part of the island's secured swimming framework that lets a few open coast beaches stay open while the rest of the sea is closed to swimming. The net protects a zone of more open water, is supervised during cover hours and is taken out when the swell is too strong, so the safe swim depends on it being in place. Always check the flags, swim only inside the zone, and never cross it.
Swimming is supervised within the netted zone during posted cover hours, commonly through the middle of the day, and you should treat swimming as open only when the beach is flagged and supervised. Exact hours vary by season and conditions and can be reduced or suspended in strong swell, so always read the signs and flags on the day. Outside cover hours, and outside the net at all times, the sea is to be treated as closed to swimming.
Roches Noires has a long surf and bodyboard reputation and is woven into the island's surf history, but surfing on Reunion is tightly controlled under the water safety rules brought in after the shark crisis, and access is limited to supervised conditions. Do not assume you can simply paddle out. If you want to surf, find the current local rules and any supervised sessions, never go alone or outside the framework, and inside the netted zone the focus is swimming rather than surf.
They suit different days. Roches Noires is the lively central town beach of Saint Gilles, sociable and convenient with bars, a marina and the island's busiest nightlife, but swimming is confined to the netted zone. L'Hermitage just south is the calm reef lagoon, shallower, safer and far better for families and snorkelling. For town life and a flagged dip choose Roches Noires, for a gentle certain swim choose the L'Hermitage lagoon, and many visitors enjoy both in a stay.
The cool dry season from May to November brings the most comfortable days, the calmest seas and the lowest rain on the west coast, and calmer water makes it more likely the net is in place and swimming open. It also overlaps the offshore whale season. Strong summer swell from December to April can see the net removed and swimming suspended. Mornings suit the swim and the surf, evenings suit the seafront.
