For something less energetic why not visit the capital of the island. Hell Ville, with it's fascinating colonial buildings. 
The town also plays host to an international music festival each May.

Whilst you are there, don't forget to go and browse through the town's market where the island's products including vanilla, coffee, pepper, saffron and other spices can be bought as well as hand embroidered linen, but be ready to barter to get the best price!

Or in the cool of the morning take a stroll from the hotel through the sugar cane fields and see the waterfall at Androadroatra with it's crystal clear opal waters.
As the day draws to a close take a trip to Mont Passot, the island's highest point, with it's sacred lakes and marvellous views and take in the sunset before descending to the hotel for a well earned  pre dinner cocktail.

Enjoy your stay.
