Despite the name (Green Cape), all the islands are barren, but they offer dramatic mountain scenery and pristine beaches. The Portuguese started colonising the islands during the 15th century and during the 16th century the archipelago became important for the supply of water and rations to boats sailing to America, Europe and Africa, and as a base for slave warehouses. The Cape Verde Islands obtained their independence from Portugal in 1975 and, although the isles may be African geographically speaking, they have retained a strong Latin flavour. Porto Grande, the port for Mindelo, is on the windward isle of São Vicente and covers an area of 88 square miles. Over 90% of the island’s inhabitants live in the capital of Mindelo, where the historic centre is characterised by old colonial houses and commemorative monuments. Please note that excursions from this port will be operated by basic minibuses: these vehicles are the best available, but lack air-conditioning, reclining seats and seat belts, and have no space for the storage of walkers or wheelchairs.
