Île de Mogador
Île de Mogador information
Lonely Planet review
Just off the coast to the southwest is the Île de Mogador, which has some interesting structures. It's actually two islands and several tiny islets – also known as the famed Îles Purpuraires (Purple Isles) of antiquity. The uninhabited islands are a sanctuary for Eleonora's falcons, which can also be easily seen through binoculars from Essaouira beach.
It is possible to arrange a private boat trip to the islands outside the breeding season, but you need to obtain a permit (free) from the port office; with that in hand, head for the small fishing boats to negotiate the trip out there. If you want to stay a few hours, fix a time for the boat to come and pick you up.
