Trou d'Eau is the beach the snorkellers and the families of the west coast quietly love, the shallowest, gentlest end of the great La Saline lagoon. Where L'Hermitage trades on its name and Boucan Canot on its style, Trou d'Eau trades on its water, a barely waist deep band of glass clear reef lagoon that runs warm and calm along a modest strip of white sand under the filao pines. On a still morning, with the light flat and the water like a held breath over the coral, it is one of the most restful and rewarding stretches of swimming water on the island, even if the beach itself is simple.
The honest read is that you come to Trou d'Eau for the lagoon, not for the trimmings. This is a basic local beach, with a car park, some shade and a few snack spots rather than any polish, and at weekends it fills with island families who know exactly how good the water is, so it can be busy and lively. But what it offers is genuinely special, some of the shallowest, calmest and clearest reef lagoon on the coast, rarely more than two metres deep, with healthy coral and dozens of reef fish close enough to watch from the surface. For easy, safe, fish filled snorkelling it rivals anywhere on the island.
So our verdict is to treat Trou d'Eau as the west coast's finest easy snorkel and family swim, and to set your expectations to the water rather than the sand. Come on a still dry season weekday morning, ideally near low tide, bring your own mask, shade and lunch, and float the shallow lagoon over the coral while keeping inside the reef and the marked areas. Pair it with the livelier L'Hermitage or the shaded Cap Homard along the same lagoon for variety, and read Trou d'Eau for exactly what it is, a modest beach over an exceptional piece of protected, swimmable water.
Trou d'Eau is a free public lagoon beach backed by pines and simple snack spots rather than a daybed club. We describe it honestly and route enquiries through our directory, never inventing fees or amenities.
The Trou d'Eau beach life is the filao shade along the lagoon, the car park snorkel and paddleboard rental nearby and the snack spots and cafes of La Saline les Bains, rather than a reserved daybed venue. Verdict: the west coast's best easy snorkel and family swim front for a calm shallow lagoon day and a relaxed local lunch, mostly pay as you order, with opening hours and any service to be confirmed by the venue.
Trou d'Eau sits at the southern end of La Saline les Bains on the west coast, about an hour from the airport at Saint Denis on the coastal road, signed off the lagoon front with a car park behind the beach roughly 250 metres before the Akoya hotel. It is in continuity with L'Hermitage and Cap Homard along the same lagoon, so the calm reef beaches pair easily, and a hire car is the simplest way to reach it.
Swim and snorkel inside the lagoon bathing areas only, check the flags and signs, and treat the open sea beyond the reef as off limits. Come on a still dry season weekday morning near low tide for the clearest, calmest water and the best snorkelling, bring your own mask, shade, water and lunch since the beach is simple, keep children in the shallows and supervised, carry small cash, and follow all local guidance, remembering conditions are typical and never guaranteed.

Yes, and it is among the easiest swims on the island. Trou d'Eau holds some of the shallowest, calmest lagoon water on the west coast, sheltered by the reef and rarely more than two metres deep, warm and clear. Swim within the marked lagoon bathing areas, read the flags, and stay inside the reef, since the open ocean beyond it carries the island's wider water risks and is not a swimming area. Keep children in the shallows and supervised, and treat conditions as typical rather than guaranteed.
Yes, it is one of the best easy snorkelling spots on the island. The shallow, calm, clear lagoon holds well preserved coral and dozens of reef fish such as triggerfish, butterflyfish and wrasse close in, all visible from the surface in barely waist deep water. Go on a still dry season morning near low tide for the best clarity, stay inside the reef and the marked areas, and tread carefully to protect the coral. The open sea beyond the reef is off limits, and conditions are typical and never guaranteed.
Yes, it is one of the gentlest family beaches on the coast. The lagoon is shallow, warm and calm, rarely deeper than two metres, with snorkel and paddleboard rental nearby, filao shade and a car park behind the sand. It is a simple local beach rather than a polished resort front, so bring your own mask, shade, water and lunch, and come on a quiet weekday morning for the calmest water. Keep children in the shallows, swim inside the lagoon only, and follow the local flags.
They share the same lagoon and differ in feel. L'Hermitage is the lively, signature stretch with beach restaurants and bigger crowds, while Trou d'Eau is shallower, quieter and more local, with arguably the easier snorkelling and gentler swimming of the two. For atmosphere and facilities choose L'Hermitage, for shallow calm water and easy snorkelling choose Trou d'Eau, and since they sit minutes apart along the same lagoon, many families enjoy both across a stay.
Yes, it is a free public lagoon beach with open access and no admission fee, and there is a car park behind the sand, roughly 250 metres before the Akoya hotel, busier at weekends. There is no reserved daybed club, so bring your own towel, mask and parasol and use the La Saline snack spots and cafes for food, with snorkel and paddleboard rental nearby. Arrive earlier on fine weekends, carry small cash, and expect simple amenities with hours that vary.
The cool dry season from May to November gives the calmest seas, the lowest rain and the clearest lagoon water for swimming and snorkelling, and it overlaps the offshore whale season. A still dry season weekday morning near low tide is calmest, clearest and best for snorkelling, since weekends draw island families. Summer from December to April is hotter, wetter and more swell prone, though the shallow lagoon stays relatively sheltered. See our Reunion when to go guide for the detail.
