The Shards round Cabo de Gata and find isolated anchorages at the foot of the dramatic Costa Blanca mountain ranges including some where the beaches are "clothing optional". They visit ports along the way that were once important Roman mining colonies and in Calpe, Paul and Sheryl climb the monolith, Penon de Ifach. Later, they attempt to sail to the Balearic Islands but are forced to turn back due to poor conditions. They eventually arrive at the island paradise of Espalmador where, with lots of humour, Paul and Sheryl try out nude sunbathing and discover the healing properties of the local mud baths.
