Learn about the local history of Moroni with a stop at Old Friday Mosque. Wander the white-sand beaches and waterfront while you're in the area.
I was here for business, but if you come for leisure, I would suggest visiting the old city around the harbour and then going out into the island to visit the newly created National Parks (Karthala - the volcano - and Coelacanthe - the marine park).
Wouldn't be my number 1 choice for a vacation; but made the best of a work destination that I had to visit. You can negotiate an island tour with one or the other of the guys offering car rental & other services, usually parked on the hotel grounds
