Trou aux Biches is a beach village on the northwest coast of Mauritius, roughly 20 kilometres by road from Port Louis. It is also known for one of the island’s calmest lagoons, fine white sand, and a reef that makes it a consistently recommended snorkeling destination. The beach faces west, which gives it a direct view of the sunset over the Indian Ocean. Its position between Port Louis and Grand Baie also makes it a practical base for self-drive visitors exploring the northwest.

Where Is Trou aux Biches and How Do You Get There?
Trou aux Biches sits on the northwest coast of Mauritius in the Pamplemousses District. It is roughly 20 kilometres by road north of Port Louis and 7 to 8 kilometres by road south of Grand Baie. The coastal road connecting the two passes directly through the village. As a result, it is easily accessible from either direction without requiring inland detours.
By hire car, the drive from Sir Seewoosagur Ramgoolam International Airport takes around 65 to 70 minutes depending on traffic around Port Louis. Bus services also run along the northwest coast road. However, they are slower and better suited to visitors staying in the area rather than arriving from the south. Parking is also available in and around the village, and the beach itself is publicly accessible. For visitors planning the wider north coast, things to do in north Mauritius covers the full region from Port Louis to Cap Malheureux.
What Is the Beach at Trou aux Biches Like?
Trou aux Biches Beach is a long, open strip of fine-grained white sand. A barrier reef shelters it and creates a calm, shallow lagoon for most of its length. The reef reduces wave action significantly, keeping the water flat and clear under calm conditions. For this reason, it draws both families with young children and snorkelers looking for visibility rather than surf.
The beach itself is public. Vendors on the public beach may offer chairs and umbrellas for hire, but availability varies, so bring sun protection and drinking water. The lagoon is calm and shallow for much of the beach. Water temperature typically ranges from about 27 to 28 degrees Celsius in summer to about 23 to 25 degrees in winter. Reef shoes are worth wearing, because stonefish and sea urchins can sit unnoticed on sand, rocks, or coral.

What Can You Do at Trou aux Biches?
The reef offshore provides some of the most accessible snorkeling on the north coast. Coral formations and tropical reef fish are also within swimming distance of the shore. Snorkeling gear is available for hire from several operators on the beach. So you do not need a boat trip to reach the reef from this location. Mauritius Now also describes Trou aux Biches as a great place to snorkel or dive.
Water sports operators on the beach offer glass-bottom boat excursions, parasailing, and paddleboarding. Independent vendors set the prices rather than fixed rates. For visitors not interested in water activities, the beach is well suited to long walks at low tide when the sand width increases. The village behind the beach also has several restaurants and small shops. They primarily serve the resort and guesthouse clientele rather than day-trippers. However, the selection is adequate for a full day spent in the area.
What Is the Sunset at Trou aux Biches Like?
Trou aux Biches is a great place to watch the sunset. This is because it faces west, with an unobstructed view of the horizon over the Indian Ocean. At sunset, the light falls directly onto the lagoon surface rather than behind the viewer or blocked by headland. This is not the case at most of Mauritius’s east-facing beaches.
The beach begins to draw larger numbers of visitors from around 5 pm on clear evenings. So arriving by 4:30 pm secures a good position without the later crowd. North Mauritius beaches with the best sunset views covers Trou aux Biches alongside other north coast alternatives. These include Cap Malheureux and Mont Choisy, and the guide compares what each offers at golden hour.
How Does Trou aux Biches Compare to Grand Baie?
Trou aux Biches and Grand Baie are two of the best-known beach destinations on the northwest coast. However, they suit different types of visitors.
| Trou aux Biches | Grand Baie | |
|---|---|---|
| Atmosphere | Quieter, more residential | Livelier, more commercial |
| Beach character | Open lagoon, better for snorkeling | More active, more water sports operators |
| Sunset quality | Direct west-facing, stronger light | Also west-facing but with more headland |
| Restaurants and nightlife | Limited, resort-led | Wide range, independent venues |
| Families | Strong choice, calm lagoon | Good but busier |

When Is the Best Time to Visit Trou aux Biches?
May to October is the dry season and the most consistent period for beach visits at Trou aux Biches. During these months, trade winds keep temperatures manageable and rain is infrequent. Visibility for snorkeling is generally good. The beach is busier in July and August when European summer holidaymakers arrive in larger numbers.
However, November to April is the warmer, wetter season, with higher humidity and the possibility of short tropical downpours. The official cyclone season runs from November to mid-May, and activity usually peaks between January and March. Check the Mauritius Meteorological Services for current warnings. Even so, the lagoon remains swimmable for most of the wet season outside active storm periods.
