Leave Mahébourg at 8:30 am, ideally on a Monday, its big market day: stalls of vegetables, pickles, fabrics and the island's best coconut alouda. Stroll along the waterfront for an hour, peek into the National History Museum (free) and take the coastal road south — the real one, hugging the water through Pointe d'Esny and Blue Bay, with Ile aux Aigrettes as a backdrop.
Second stop: Gris Gris and the Roche qui Pleure, near Souillac. No protective reef here: the ocean slams straight into the cliffs and the spray rises ten metres high. The lower path (15 minutes, free) takes you right down to the rollers — sensational, but you never swim here. At noon, sit down at Chez Rosy, the Gris Gris institution, for a fish curry or saffron octopus at Rs 350 – 450.
The afternoon starts with Rochester Falls, where water drops in basalt organ pipes amid the cane fields — free access, bumpy track, politely decline the improvised « guides » in the car park. Then head to the Saint-Aubin estate or the Bois Chéri factory depending on the hour: rum and vanilla at one, tea overlooking the sacred lake at the other (tours Rs 400 – 550, last entries around 3:30 – 4 pm).
Rejoin the B9, the country's most beautiful coastal road: Riambel and its endless lagoon, Pointe aux Roches and its leaning filaos, then Baie du Cap and the legendary Maconde bend. Climb the few steps of the lookout: the view over the bay and the road curling under the cliff is THE wild South photo. Along the way, pineapple and coconut sellers line the road — happiness for Rs 50.
Finish in style at Le Morne Brabant for sunset, facing the UNESCO-listed mountain, memorial to the resistance of the maroon slaves. Count 120 kilometres in total from Mahébourg, doable in a rental car or with a driver for the day (Rs 4,000 – 4,500). Local tip: leave early and drive the route east to west — you'll always have the sun at your back for photos.
