short sail from Marina da Quinta do Lorde, the Cais do Sardinha is a small jetty nestled beneath the cliffs of the eastern peninsula. It serves as the gateway to Ponta de São Lourenço by sea the same point where kayakers and snorkellers set off to explore the reserve from the water. From here, the coastline opens up into one of the most striking seascapes in Madeira. But there is something else worth knowing about this stretch of water. Just offshore from the Cais do Sardinha, you will notice a cluster of floating cages an open sea aquaculture farm operating in the Baía de Abra, producing several hundred tonnes of fish per year. It is a working part of the local economy, and it also attracts an occasional, very special visitor.
