Morning light slices through humid air as the catamaran slips off Port Douglas and heads east toward Low Isles. The reef rises like a shallow bank below the surface; the lagoon’s sheltered waters shimmer a pale aquamarine. On arrival, you’ll step from boat ladder into warm, calm water and find coral gardens that spread like living pavements beneath you, while a glass-bottom boat traces the shallows for those who stay dry.
