Marina do Clube Naval de Sesimbra

Run by the Clube Naval de Sesimbra, this marina packs in a serious range of facilities — diving center, sailing and kayaking schools, crane services, and a sports fishing setup — making it one of the more well-rounded spots on the Setúbal Peninsula. Sesimbra itself is a gem, a sheltered fishing village with a Moorish castle looming overhead and some of the clearest water on Portugal's Atlantic coast right on your doorstep.
