The Short Answer
The east and west coasts of Mauritius feel like two different islands. The east is defined by long, shallow-lagoon beaches and some of the finest white sand in the Indian Ocean. The west is wilder — dramatic, wind-sculpted, with a backdrop of basalt peaks and the island's most consistent diving. Which is better depends almost entirely on when you're travelling.

Weather: The Deciding Factor
Mauritius's trade winds blow from the south-east. This single fact drives the core difference between the two coasts:
- East coast (May–October): Directly exposed to the south-east trades. The lagoon can be choppy, with surface chop making it uncomfortable for swimming from the shore. Windier conditions are most pronounced in July and August. The beach is still beautiful, but the water is rarely flat.
- West coast (May–October): Sheltered behind the island's central plateau and mountain ranges. The water in the bay at Flic en Flac and in the Le Morne lagoon is typically flat and calm. July and August — peak European summer travel — are actually the west coast's finest months.
- East coast (November–April): The trade winds ease, the lagoon becomes glassy and warm, and visibility for snorkelling peaks. This is the east coast's moment — the water is simply extraordinary from December to March, if you can tolerate the higher humidity and occasional rain shower.
- West coast (November–April): More exposed to tropical moisture and occasional cyclone-related swell. Still pleasant, but not the west coast at its best. Diving visibility can reduce with heavier rain periods.
Visiting May–October? Choose the west coast. Visiting November–April? Choose the east coast. If you're visiting in April or October (the shoulder months), both coasts are good — pick the resort you prefer.

East Coast: Belle Mare & Beau Champ
The east coast's trump card is the beach. Belle Mare beach runs for approximately 8 km of unbroken white sand, backed by casuarina trees and fronted by a shallow turquoise lagoon. It is, by most measures, the most beautiful beach in Mauritius — and one of the finest in the Indian Ocean. The water in the November–April window is exceptionally clear and warm.
The two flagship resorts here — One&Only Le Saint Géran and the Four Seasons at Anahita — are among the most acclaimed properties in the entire Indian Ocean. Constance Belle Mare Plage adds a third world-class option with two golf courses and 2 km of private beach frontage. The east coast is the destination for travellers whose priority is beach and resort quality above all else.
The nearby island of Ile aux Cerfs offers excellent shallow-water snorkelling, a golf course, and a beach that's busy with day-trippers — a fun excursion but worth going early to avoid the midday crowds.
West and South-West: Flic en Flac, Le Morne & Bel Ombre
The western coastline has three distinct zones. Flic en Flac is the most developed — a long, popular beach backed by local restaurants and dive centres, with a genuine community feel. It's the least "resort" of the three and appeals to travellers who want to mix with locals and explore off their own steam.
Le Morne is altogether more dramatic. The basalt Le Morne Brabant peninsula rises to 556 m and is a UNESCO World Heritage Site. The beach wraps around its base, the water is usually flat and clear May–October, and the kite-surfing conditions here are considered among the best in the world. Lux* Le Morne is the standout resort — stylish, contemporary, and supremely positioned.
Further south, Bel Ombre is the most remote pocket of the island. Heritage Le Telfair occupies a former colonial estate with 2,500 acres of nature reserve, an 18-km private beach, and a spa of extraordinary scale. It is the choice for couples and families who want genuine isolation with full five-star service.
For diving, the west coast is unambiguous: the reefs around Flic en Flac include some of Mauritius's most celebrated sites, including the Stella Maru wreck, excellent wall dives, and reliably good shark encounters. Visibility peaks May–October — aligning perfectly with when the west coast is also at its calmest.
Can You Stay on Both Coasts?
Absolutely — and many visitors do. The drive from Belle Mare to Le Morne takes approximately 90 minutes. A split stay of 5–7 nights on each coast gives you meaningfully different experiences without the logistics of a complicated itinerary. Most hotels will arrange a private transfer between properties.
The most popular split itinerary for a 12–14 night trip: start at a south-west property (Le Morne or Bel Ombre) for dramatic scenery and diving, then transfer to the east coast (Belle Mare or Beau Champ) for the finest beach and a different resort atmosphere. This ordering makes sense because you arrive relaxed into the more remote, quieter south-west, then end on the east coast — slightly closer to the airport for departure.
Which Coast for Your Trip?
Choose the east coast if:
- You're travelling November–April
- The beach is your top priority
- You want to stay at One&Only Le Saint Géran or the Four Seasons
- You want a shorter airport transfer (15–25 min vs 60–90 min)
- You plan to day-trip to Ile aux Cerfs or play golf
Choose the west or south-west if:
- You're travelling May–October
- Scuba diving is a priority
- You want to kite-surf at Le Morne

- You value seclusion and a quieter atmosphere over resort amenities
- You're a honeymoon couple wanting the most romantic setting
