The twenty-kilometre crossing from Santa Eulalia del Río to Formentera has been a working route since the fifteenth century, when Ibizan fishermen established seasonal camps on the smaller island's southern shore. By the mid-twentieth century, motorised passenger ferries replaced sail-powered llaüts, shortening the journey from three hours to forty minutes. Today's vessels depart from the Puerto Deportivo de Santa Eulalia, a modern marina adjacent to the historic sailing school, carrying day-trippers and locals across the Freus de Formentera channel between the Balearic archipelago's two quietest islands. Formentera remains the only inhabited Balearic island without an airport. This geographic constraint has preserved the island's character: fewer than twelve thousand permanent residents, no high-rise development, and a coastal landscape protected under Spanish coastal law since 1988. The ferry route serves as the island's primary artery, moving approximately two million passengers annually during peak season. Santa Eulalia's embarkation point lies seven kilometres north of Ibiza Town's larger commercial port, offering a less congested alternative for visitors based on the island's eastern coast. The crossing itself traces the edge of the Ses Salines Natural Park, a UNESCO World Heritage site encompassing salt flats, seagrass meadows, and migratory bird corridors. Ferry Santa Eulalia Formentera precio structures reflect the route's seasonal demand. Round-trip fares hold steady at fifty-two euros per passenger, with vessels operating daily from March through October and reduced schedules during winter months. The marina's position next to Santa Eulalia's promenade allows pedestrian access from the town centre in under ten minutes, a practical advantage over Ibiza Town's port, which requires shuttle transfers from most hotel zones. Open-return ticketing permits passengers to board any scheduled departure on the day of travel, accommodating flexible beach itineraries without advance reservations. Formentera's appeal lies in its coastline: nineteen beaches spanning a combined twelve kilometres, many accessible only by bicycle or on foot. Ses Illetes and Llevant beaches anchor the northern peninsula, their shallow turquoise waters reaching depths of less than two metres for thirty metres offshore. The island's interior remains agricultural, with stone-walled fields of carob and fig trees covering seventy percent of the landmass. Ferry operators coordinate schedules with bicycle rental kiosks at La Savina port, Formentera's lone ferry terminal, where most visitors disembark directly onto a network of dedicated cycle paths extending to every major beach and settlement.
