Cape Verde
Climb a dead volcano from the beach and count three uninhabited islands from its rim.
Lava fields run down to a working shore where fishing boats sit under bare volcanic cones. Offshore, the swell that gives this coast its surf reputation rolls in from the open Atlantic, and everything smells of salt and hot rock.
Calhau is São Vicente's east-coast counterweight to Mindelo, a fishing village a short drive across the island's arid interior. The cone beside the village is extinct and climbable, a scramble of almost 150 metres that puts the uninhabited islands of Santa Luzia, Raso and Branco on the horizon. Surf and wind schools work the exposed beaches towards Praia Grande, though the currents are serious and local advice decides what is swimmable on any given day. At weekends Mindelo drives out to eat: Chez Loutcha's Calhau branch lays on its traditional buffet with live Cape Verdean music, and the village's fish kitchens do the rest.
Solo
Cross the island, scramble the cone for the three-island view, and time the return around a plate of whatever the boats brought in.
Couple
Trade Mindelo's noise for lava fields and Atlantic light, with a long weekend lunch as the anchor of the day.
Chez Loutcha's Calhau outpost lays on its Cape Verdean buffet for the village's famous long lunches.
On other days the village's fish kitchens grill whatever the morning landed, simply and close to the water.
