Deserto de Viana, located on Boa Vista in Cape Verde, offers a unique desert landscape formed by sand blown from the Sahara. Accessibility can be challenging, typically requiring a 4x4 vehicle or a guided tour. While solo exploration is possible, a guided tour is recommended for safety and navigation. There are generally no seasonal restrictions, but the heat can be intense during the summer months. A typical visit lasts around 2-4 hours, and the cost usually includes transportation and a guide, ranging from $30 to $70 depending on the tour operator and inclusions. Be sure to bring sunscreen, water, and appropriate footwear for walking in the sand.
