Sidi Ifni was one of the last places that the Spanish left, in 1969, 13 years the rest of Morocco got its independence. And then quite involuntarily: The Moroccans closed all overland transport, and made it difficult for the little town to survive by itself. Unlike Ceuta and Melilla, Ifni had been Spanish for only a short period of time, only since 1934.
Sidi Ifni feels almost as isolated now as then. The roads to Tiznit and Goulimime are narrow and winding, and the hamlets north of Sidi Ifni are modest. Sidi Ifni is by itself a quiet place, friendly yes, but the speed might be too slow for many travellers.
