Port d'Aiguadolç opened in 1992 as Sitges' answer to Barcelona's Olympic marina boom, and within a decade its western pontoons became the preferred launch point for small-sail charters along the Garraf coast. The harbour sits beneath limestone cliffs that drop 200 metres to the waterline, sheltering the basin from northwesterly tramontana winds while funnelling reliable afternoon thermals—conditions that kept Phoenician traders anchored here two millennia before fiberglass hulls arrived. Today the port hosts 26 accredited charter operators, though only five maintain the documentation and safety audits required for commercial passenger sailing. A Sitges sailing tour distinguishes itself from motorized excursions through sail-driven propulsion and the resulting silence once engines cut beyond the breakwater. Catamarans and monohulls between 9 and 14 metres dominate the fleet, each certified for six to twelve passengers under Spanish maritime regulation. Most charters run two to three hours, tracing the coastline southwest toward Cunit or northeast past the Balmins reef, where water clarity reaches 12 metres in September and October. Sunset departures between April and September align with the sun's descent behind Montserrat's serrated ridge 40 kilometres inland, a geometry that paints the mainsail amber for twenty minutes before dusk. The Garraf Maritime Natural Park, established in 1986, prohibits anchoring inside its six protected coves, so operators hold station 200 metres offshore while guests swim or paddleboard. Cava service—standard on premium sailings—uses Penedès bottles sourced 15 kilometres inland, a nod to the region's sparkling-wine exports that predate champagne's 1891 appellation protections. Winter charters persist through March, though Mediterranean swells average 1.2 metres and require foul-weather gear. Port d'Aiguadolç remains accessible year-round, its concrete piers unchanged since construction, a utilitarian anchor for an activity defined by wind and the absence of fixed schedules.
