Grand Baie as Home Base: Northern Bays and Culture
Stay in Grand Baie in the north to see the botanical garden, the sugar museum and the red-roofed church, and take a catamaran to the northern islets.
A relaxed, in-depth route: you stay in Grand Baie in the north throughout, with convenient dining and nightlife. One day covers the Pamplemousses Botanical Garden, L'Aventure du Sucre museum, Château de Labourdonnais and Cap Malheureux; one day is a catamaran trip to snorkel at the uninhabited northern islets; one day is spent exploring the Citadel and old town of Port Louis; and on departure day you drive via the Trou aux Cerfs crater and Grand Bassin in the central plateau to the airport. The southwest highlands are left out.
The north is sheltered from the wind and warm even in winter; the January–March cyclone season can affect boat trips.
