The Massa lagoon, on the coast around 40km south of Agadir, is part of the Souss–Massa National Park, and is one of Morocco’s most important bird habitats, attracting unusual desert visitors and often packed with flamingos, avocets and ducks. The best times to visit are March to April or October to November. Most transport takes you to Massa village, from which you can walk along the oued, an area rich in birdlife, and to the beach at Sidi Rbat. It was here in 682 AD, according to legend, that the Arab general Okba Ibn Nafi, after sweeping westward with his armies to take North Africa for Islam, famously rode his horse into the ocean, declaring before God that only the sea prevented him from going further. The beach itself is often misty and overcast – even when Agadir is basking in the sun – but on a clear day, it’s as good as anywhere else and the walks are enjoyable.
