Cala Màrmols is named for marble it does not contain. Its cliffs are marès, the honey-coloured limestone that Santanyí quarried for centuries and shipped to cathedral façades across the western Mediterranean. From Cala Figuera Boat Tour to Cala Marmols & Caló de Moro tours now trace the same working coastline that once carried stone, salt and fish. Cala Figuera itself remains a fishing village rather than a resort. The inlet forks into two narrow arms lined with timber boathouses on stilts, and the fleet still returns before midday. Above the mouth stands Torre d'en Beu, a watchtower raised in the sixteenth century against Barbary raiders. From its platform a signal fire could be answered at Cap de ses Salines, where the lighthouse has burned since 1863. The water between those points is the Migjorn coast: low cliffs, no rivers, no silt. Visibility is a product of that geology. Posidonia oceanica meadows filter the shallows and hold the sand in place, which is why Caló des Moro reads turquoise against pale rock rather than the green of a mainland bay. Halfway along, Es Pontàs stands offshore, a limestone arch cut by swell and rain, known to climbers as the line Chris Sharma first freed in 2006. Locals still call the passage simply an excursión en barco, and a Mallorca coastal boat tour of this stretch remains the oldest way to read it. Cala Màrmols sits further south, below the last cliffs before the cape. No road reaches it. The alternatives are ninety minutes on foot across open garrigue from Cala Llombards, or a keel. That isolation preserved it: no bar, no boardwalk, no lifeguard, and a beach the same width it held a century ago. Caló des Moro, by contrast, is a thirty-metre notch below Caló s'Almunia, reached by a rock staircase, and photographs of it circulated widely enough after 2015 to turn coastal access into a municipal question. Both coves lie within the Municipality of Santanyí, Southeast Mallorca, Spain, and both are free to enter — a natural site with no official gate. Seen from the water they read as one geological sentence: the same strata, the same erosion, different endings. The From Cala Figuera Boat Tour to Cala Marmols & Caló de Moro tour exists because the land route separates what the sea keeps together. Catamarans and rigid-hulled craft out of the Santanyí harbours have made the crossing routine, and the coast is now more legible from a deck than from any clifftop path.
