Visas & entry
We booked our villa months ahead after reading how quickly accommodation fills in Grand Baie, and picking somewhere close to the beach made the whole stay easier to plan day to day. Public buses got us between beaches cheaply during the day, though we always confirmed taxi fares before getting in to avoid the inflated tourist pricing a few drivers tried on us. The bazaar in the center of town was our go-to for evening street food and a bit of bargaining over jewelry and fabric souvenirs. We tried our first underwater sea walk here, a strange but memorable way to see the reef without full diving certification, and the Stella Maru shipwreck drew every diver in our group back for a second visit.
