Is there a dive shop at Anse Royale where I can get a snorkelling kit?
Yes there is a Padi Dive shop in Anse Royale. You can find it in the same building as MCB, and Dauphins Restaurant, opposite to the hospital in Anse Royale.
Thanks Francesca! We found a beach shop and managed to get mask and fins. They've got quite a selection of items there - swim suits, beach toys, sunscreen, etc.
