The volcanic landscape of Sal provides a very special geographical feature – the salt lakes of Pedra de Lume. These lakes – or ‘salinas' – are located in the crater of an extinct volcano and form the lowest point in Cape Verde.
As you enter the waters, you won't have to paddle too hard to stay afloat – the waters are 26-times denser than sea water, so you'll bob around in them like a cork. The Dead Sea is just 10-times denser.
Soaking in this natural wonder isn't the only serene activity on this afternoon excursion – you'll be treated to a wonderfully relaxing spa treatment in the Salinas spa centre before you brave the salty waters. Bring a towel, though – you're going to want to shower all that salt off you before returning to Santa Maria.
