Boat-access Cascais reef with octopus, wrasse, and rock relief.
Maria Alice is a compact Cascais reef dived for rocky outcrops, pale sand channels, and the kind of Atlantic temperate life that rewards slow looking rather than big-ticket spectacle. It works best as a short boat-supported local dive, where octopus, wrasse, and bream give the site its character and settled sea state makes the reef feel relaxed and photogenic.
