From the Cova volcanic crater at 1700m above sea level, a path winds down to the northwest coast of Santo Antao through one of the most fertile valleys of the Cape Verde Islands. Water flows through the valley all year round, even outside the rainy season, and accordingly, the diversity of tropical plant life is immense. Mangoes, papayas, bananas, and grapefruits grow here, as do sugar cane, squash, and cassava. Magnificent blossoms form colourful fountains amidst the lush green.
