The limestone archipelago of Paxos lies seventeen nautical miles south of Corfu, small enough to circle on foot in a day yet dense with Venetian harbours, olive terraces, and sea caves carved by millennial wave action. Since the early 1980s, Paleokastritsa — Corfu's western anchor — has served as the principal departure point for day cruises to Paxos and its satellite island, Antipaxos, a route that cuts across the Ionian's deepest channel and delivers passengers to coastlines inaccessible by road. Paleokastritsa boat trips to Paxos depart between nine and ten in the morning, timed to catch the northwesterly meltemi winds before they build in the afternoon. The crossing takes ninety minutes aboard steel-hulled day cruisers or catamaran ferries, passing the uninhabited islet of Othonoi to starboard and entering Paxos waters near the marble-white cliffs of Erimitis. Most itineraries include a two-hour stop in Gaios, the island's Venetian-built capital, where pastel neoclassical facades line a harbour protected by twin islets. The second leg continues south to Antipaxos, where the turquoise shallows of Voutoumi Beach — fed by underwater springs — draw swimmers into water so clear that anchored hulls appear suspended in air. The northern half of the Paxos route threads through the Blue Caves, a chain of collapsed limestone chambers along the island's western escarpment. Sunlight refracts through submerged calcium carbonate, casting cyan and indigo gradients onto vaulted ceilings. Operators navigate inflatable tenders into the largest caverns, where stalactites hang above saltwater pools maintained at eighteen degrees Celsius year-round. The geological strata here — Cretaceous-era limestone over Jurassic dolomite — erode at a rate measured in centimetres per century, a process visible in the scalloped cave walls and natural arches that punctuate the coastline. Paxos cruise operators from Paleokastritsa maintain a mixed fleet: open-deck motor launches for groups of fifty to eighty, and luxury catamarans with shaded saloons and onboard galley service. The island hopping tours typically allocate four to five hours ashore across both islands, sufficient time to walk the flagstone alleys of Gaios, swim in Antipaxos's twin bays, and return to Paleokastritsa by early evening. The route has operated without interruption since 1982, when the first licensed day cruises replaced informal caïque charters, and remains the only scheduled maritime link between Corfu's northwest coast and the Paxos archipelago.
