Garajau Natural Reserve

Portugal's oldest marine protected area drapes along Madeira's southern cliffs, where barracuda school in silver curtains above meadows of sea grass and common stingrays rest half-buried in sandy lanes between boulders. Dense aggregations of Mediterranean moray eels occupy every crevice of the basalt reef, while Atlantic trumpet fish drift vertically among sea fans waiting to ambush wrasse. The reserve's strict no-take status since 1986 has produced fish biomass that rivals open-ocean seamounts, making each dive feel like an encounter with a genuinely wild Atlantic reef.
