Introduction
Boa Vista is best known for its beaches and July-to-October turtle nesting — two further pieces of ground round out the island's story: why a literal desert exists here, and the whale season that runs opposite the turtles' own.
Overview
The Viana Desert exists on Boa Vista for a specific reason tied to the island's geography: Boa Vista sits closer to the West African mainland than any other Cape Verde island, directly in the path of Saharan dust and sand carried west on the trade winds, and centuries of that wind-blown deposit have built genuine dune fields and a flat, sand-covered desert plain unlike anything else in the archipelago — a small piece of the Sahara that made an Atlantic crossing grain by grain rather than a volcanic or coastal feature like the rest of the island's landscape. Boa Vista's other seasonal wildlife draw runs on the opposite calendar from its famous turtles: humpback whales migrate past the island's waters roughly February to April, travelling between winter breeding grounds and summer feeding areas, and boat trips from Sal Rei during those months offer a genuine chance at sightings during exactly the stretch of the year when the turtles are absent.
Discover Boa Vista
Boa Vista's position as the Cape Verde island closest to the West African mainland puts it directly in the path of Saharan dust and sand carried out over the Atlantic on the trade winds, and centuries of that wind-blown deposit accumulating on the island's flat eastern terrain built the Viana Desert — genuine dune fields and a sand-covered plain that looks more like inland Mauritania than a volcanic Atlantic island. It's a mechanism distinct from the rest of Boa Vista's landscape, which is shaped by the same volcanic origins as the other islands; the desert is imported material rather than something the island produced itself, making it one of the more genuinely surprising landscapes in the whole archipelago.
