Read the full experience

The day opens with a pale-light breakfast at Tab Lamu Pier, the catamaran’s engines humming like a promise as the shoreline slips away. Within an hour the water unspools into turquoise—clear enough that reef shadows seem to reach for the boat—then the archipelago’s granite domes rise from the sea: white beaches, wind-sculpted boulders and the steep steps to Sail Rock viewpoint.
