Pale sand, a calm lagoon, easy snorkelling and sunsets: Trou aux Biches brings together everything people come looking for on a beach in the north of Mauritius, with a gentleness that is ideal for families or couples.
Trou aux Biches has that immediate charm of beaches you recognise before you have even laid down your towel: a long curve of pale sand, casuarina and palm trees along its edge, a shallow turquoise lagoon, then the horizon opening gently towards the west. Located on the north-west coast of Mauritius, between Pointe aux Piments and Mont Choisy, this public beach is regularly cited among the most beautiful on the island because it combines, with no apparent effort, what many travellers hope to find here: calm water, easy swimming, marine life close to shore and a particularly soft late-afternoon light.
From Grand Baie, Trou aux Biches is easy to reach for a half day at the beach, a snorkelling outing, a lunch with your feet almost in the sand or a sunset. It is also a precious address for couples planning a romantic stay in the north, as well as for families looking for a reassuring sea with children. Here is a practical guide to enjoying Trou aux Biches at the right time, in the right spot, without missing what has made its reputation.
Why Trou aux Biches is one of the emblematic beaches of Mauritius
The first quality of Trou aux Biches is its balance. The beach is beautiful without being hard to reach, lively without entirely losing its calm, family-friendly without giving up the postcard scenery. The sand is fine, pale and pleasant underfoot, with the light shade of casuarina trees in places. The lagoon deepens gradually, so you can walk into the water easily, with no sudden drop near the shore.
The north-west coast of Mauritius is generally more sheltered than some exposed stretches of the east and south. At Trou aux Biches, the offshore reef protects the lagoon, creating a sea that is often calm, especially in the morning. This configuration partly explains why the beach is so popular with families and unhurried swimmers. Depending on the hour, the water takes on shades of pale blue, turquoise and translucent green. As the sun sinks, the colours warm up, the silhouettes of the boats stand out, and the mood becomes more intimate.
The beach is long, but not all its stretches are equal. Some areas are closer to the water-sports activity, others better suited to quiet swimming or reading in the shade. The right reflex is to walk along the shore for a few minutes before settling down. You will quickly spot the calmest sections, the boat zones, the pockets of shade and the most convenient access points.
An ideal beach for swimming with children
Trou aux Biches is often recommended to families because swimming there is simple. The lagoon stays shallow for a good distance, the entry into the water is gentle and the sand remains comfortable. For young children this is a real advantage: they can play at the edge, move forward gradually, watch the little fish near the rocks or the seagrass, while staying under close supervision.
As everywhere in Mauritius, caution is still needed. Conditions change with the wind, the tide and passing boats. It is best to choose an area clearly dedicated to swimming, keep children within arm’s reach and avoid swimming in the channels or near the boats. Water shoes can be useful for sensitive feet, particularly near coral or rocky patches.
Morning is often the best time for a family swim. The sea is smoother, the heat still pleasant, the beach less busy. By late morning and in the afternoon the mood becomes livelier, with more visitors, more activity and more movement on the lagoon. If you come with very young children, bring water, sun protection, a hat and plan a break in the shade: the Mauritian sun can be intense even when the breeze makes it feel cooler.
Snorkelling at Trou aux Biches: an easy, lively spot
Snorkelling is one of the great attractions of Trou aux Biches. Without going far, you can watch tropical fish and coral patches relatively close to the shore. That is what makes the place so loved: it suits beginners, children already confident in the water and travellers who want to discover the lagoon without committing to anything too technical.
The best moments for swimming with mask and snorkel are generally in the morning, when the water is clearer and the surface less choppy. Visibility always depends on the weather, the tide, the wind and boat traffic, but Trou aux Biches remains one of the easy spots in the north for observing marine life. You can see colourful fish near the coral, sometimes in small schools, as well as seagrass beds sheltering more discreet creatures.
To enjoy it without causing damage, keep one simple rule: look, do not touch. Corals are alive and fragile. Avoid standing on them, do not collect pieces, do not feed the fish and keep a respectful distance. A reef-friendly sunscreen applied in advance and a UV-protection top are good ways to limit your impact while protecting yourself.
Where to get into the water for snorkelling
The interesting areas tend to be where the seabed varies: small corals, rocks, seagrass, gradients of colour in the water. Avoid the zones heavily used by boats or water-sports operators. Before swimming out, study the lagoon from the sand: darker patches often indicate different seabeds, sometimes richer in marine life, but they can also signal seagrass or areas less comfortable to walk on.
If you are a beginner, stay parallel to the beach and do not stray too far. The idea is not to chase performance, but to drift gently, breathe calmly and take the time to watch. With children, choose a short session in calm water and come back to the shore regularly.
The sunset: the beach’s great daily event
Trou aux Biches faces west, and that changes everything at the end of the day. The sun sinks towards the ocean, the light settles on the lagoon, the boats become slender shadows and the colours shift from blue to gold, then to pink or orange depending on the clouds. It is one of the most pleasant moments of the day, especially after the afternoon heat.
For a couple, this is a naturally romantic beach, with no need for excessive staging. A barefoot walk, a quiet swim, a drink on the way back, a few photos in the low light: simplicity is often enough. Those imagining a marriage proposal on the beach will find a very gentle setting at Trou aux Biches, provided they choose a peaceful spot and a well-thought-out time. For a truly intimate moment, it is better to avoid the busiest stretch and arrange things discreetly in advance.
The sunset draws a crowd, especially during holiday periods and at weekends. Arrive a little before the end of the day to settle in without stress, find a pleasant spot and enjoy the shifting light. After sunset the beach darkens quite quickly: keep your belongings together and plan your journey back.
Water sports and boat trips around Trou aux Biches
Trou aux Biches is not just a beach for lazing. Depending on the period and the operators present, you will find various water activities: glass-bottom boat, kayak, stand-up paddle, tube rides, water-skiing or guided snorkelling outings. What is on offer varies with the weather, the season and the providers. The wisest approach is to check the day’s conditions on site, along with the supervision, the life jackets, the timetables and the navigation zones.
For sea lovers, the north of Mauritius also makes it easy to reach Grand Baie, a common departure point for boat excursions to the northern islets, such as Coin de Mire, Flat Island or Gabriel Island, when conditions allow. These trips offer another reading of the region: volcanic cliffs, deeper open blues, snorkelling in the open sea and lunch on board depending on the package.
Travellers who dream of watching dolphins can ask about a dolphin outing at first light. Dolphins are wild animals, and their presence is never guaranteed. The most responsible outings favour respectful observation, without chasing or intrusive swimming. From the north, some excursions are organised with a local departure or a transfer to other parts of the island, notably the west coast, known for this kind of observation. Before booking, ask precise questions about the approach taken and choose an operator attentive to the animals’ wellbeing.
The Pointe aux Piments aquarium, an easy stop nearby
A few minutes south of Trou aux Biches, Pointe aux Piments is home to an aquarium that can round off a day in the area very nicely, particularly with children. It is a practical option when the heat is strong, when the sky clouds over or when you want to understand better the species you have seen in the lagoon.
The experience obviously does not replace snorkelling, but it helps to identify certain fish, to observe marine creatures at closer range and to make younger visitors aware of the fragile richness of the Indian Ocean. After the visit, you can head back to Trou aux Biches for a swim or continue towards Mont Choisy and Grand Baie.
Where to eat at Trou aux Biches
The beach and its surroundings offer several options for lunch or dinner without going far. The mood stays fairly laid-back: Mauritian snack bars, small local addresses, restaurants near the coastal road, hotel tables open to outside guests depending on the establishment, and more varied options towards Grand Baie. For a simple meal, look for specialities such as fried noodles, fried rice, boulettes, a farata or a fish dish, depending on which addresses are open on the day of your visit.
If you want to stay in your swimsuit and make the most of the beach, go for a quick bite nearby, then come back and settle in the shade. For a more leisurely dinner after sunset, Grand Baie offers far more choice, with Mauritian, Indian, Asian, Mediterranean and seafood restaurants. From Trou aux Biches, the journey is short by car or taxi outside the busiest traffic.
One simple piece of advice: do not leave your litter on the beach, even for a few minutes. Mauritian beaches are living spaces shared by residents, families, fishermen, visitors and the lagoon’s wildlife. Keeping your spot clean is part of the experience.
Access, parking and practical tips
Trou aux Biches sits on the north-west coastal road, between Pointe aux Piments and Mont Choisy. From Grand Baie, access is direct by road, by car, taxi or bus depending on how you organise yourself. The beach has public access points, but parking can become limited at the busiest hours. The spaces close to the shore go quickly, especially at weekends, during school holidays and in the late afternoon.
If you come by car, arrive early in the morning or later in the afternoon. Park without blocking entrances, residents, shops or traffic. When it is busy, it is better to accept a short walk rather than hunt for the perfect space. If you are staying in the north, a taxi can be a comfortable solution, especially for enjoying the sunset without worrying about the drive back or the parking.
What to pack in your bag
- Mask and snorkel to enjoy the nearby seabed without depending on a rental.
- Sun protection, a hat, sunglasses and a UV top, especially for children.
- A light towel or a sarong, easier to carry than bulky beach gear.
- Water, in sufficient quantity, because the heat makes itself felt quickly.
- Water shoes if you are sensitive to dead coral, rocks or small natural debris.
- A bag for your litter so you leave with everything you brought.
The best time to avoid the crowds
To enjoy Trou aux Biches at its most peaceful, come early. The first hours of the morning often offer the best conditions: fresh light, a calmer sea, less occupied sand, more pleasant snorkelling. It is also the ideal moment for photos, with a light less harsh than at midday.
The busiest window generally falls between late morning and the afternoon, especially in fine weather. The sunset draws people again, but the mood is different: they come to walk, admire the light, end the day. If you are looking for absolute calm, choose a weekday and avoid local holiday periods when possible.
As for the season, Mauritius can be visited all year round. From May to October the climate is drier and milder, with trade winds sometimes present. From November to April temperatures are hotter and the air more humid, with more possible showers; this is also the cyclone season in the south-west Indian Ocean. In the north-west, the days can remain magnificent in any season, but sea conditions and visibility change from one day to the next.
Combine it with Mont Choisy and Grand Baie
Trou aux Biches lends itself very well to a gentle itinerary in the north. Right next door, Mont Choisy offers a longer beach lined with casuarina trees, perfect for walking, swimming or settling into an often more open atmosphere. Where Trou aux Biches charms with its lively lagoon and postcard looks, Mont Choisy gives a feeling of space. The two beaches complement each other very well in a single day.
You can start with Trou aux Biches in the morning for the snorkelling, have lunch nearby, then move on to Mont Choisy for a walk or a quieter swim. At the end of the day, come back to Trou aux Biches for the sunset, or continue to Grand Baie for dinner.
Grand Baie, for its part, brings the buzz: marina, boutiques, restaurants, excursion departures, a more present nightlife. It is a practical base for exploring the north while keeping quieter beaches within easy reach. From Mandala Moris, this combination lets you build a flexible day without long drives: beach in the morning, a pause at the hotel, a boat trip or dinner in the evening.
A simple day plan for Trou aux Biches
To avoid rushing, start early. Arrive at Trou aux Biches at the start of the morning, settle in a calm area and go for a first swim. If the sea is clear, follow it with a short snorkelling session. Take your time: watch the fish, come back to the shore, drink some water, let the beach wake up.
At the end of the morning, take a break in the shade or go for lunch nearby. If you are travelling with children, this is the right moment for a gentler activity, such as the Pointe aux Piments aquarium, before returning to the sea once the heat eases.
In the afternoon, choose between Mont Choisy for walking and swimming, Grand Baie for an outing or a few purchases, or simply a return to Trou aux Biches. Keep the sunset as your anchor point. It is often this final moment that stays in the memory: the calm lagoon, the changing colours, the conversations slowing down.
Who is Trou aux Biches the best beach for?
Trou aux Biches particularly suits those who want a beach that is beautiful, easy and complete. Families find gently shelving water. Couples find a romantic light and more peaceful corners if they look a little. Beginner snorkellers find simple access to the underwater world. Travellers who do not fancy spending the day on the road appreciate how close it is to the other stops in the north.
On the other hand, if you are looking for a completely wild, isolated beach, Trou aux Biches is not always the right choice, especially at peak hours. It is well known, well loved, well visited. Its charm reveals itself fully when you pick the right time and accept a few minutes’ walk to find your own space.

Trou aux Biches deserves its reputation because it remains easy to live with: the swimming is effortless, the lagoon reveals itself without fuss, lunch is uncomplicated and the day ends in front of one of the beautiful sunsets of the north-west. To make the most of it from Grand Baie, choose your timing, keep room for Mont Choisy or Pointe aux Piments, and let the north of Mauritius unfold its quiet rhythm.
