Overtourism Is Pushing Sardinia's Marine Park Toward Ecological CollapseThe clearest snapshot of what overtourism looks like in Sardinia in 2026 happened just before Ferragosto, in the waters off the island of Mortorio inside the La Maddalena National Park. Dozens of yachts, catamarans and inflatable boats gathered in a fully protected zone, and one captain rigged up a sound system to blast music across the water, turning the anchorage into what quickly became known online as a floating discotheque. A video that circulated widely showed someone singing into a microphone as the crowd around them danced. It was, by every account, only the most brazen violation of a summer that had already seen weeks of smaller ones.Park president Rosanna Giudice didn't mince words describing what's been happening across the archipelago all season, comparing the influx of boats and tourists to a locust invasion. The park's own regulations cap daily seaborne visitors at 2,500 people. This summer, aerial surveys conducted over multiple days showed the real number hitting 6,500 a day, and possibly higher.An Ecosystem Under Direct Physical AssaultThe damage isn't abstract. Giant yachts have been edging dangerously close to shorelines they're required to stay at least 500 meters from in the park's most protected zones, and dropping anchor directly onto posidonia meadows, the underwater seagrass beds that anchor the Mediterranean's marine ecosystem and are officially protected under EU law. Aerial footage from Cala Coticcio showed roughly 135 boats, from small inflatables to large yachts, crammed into a single small cove, each carving out its own patch of water in what one local paper described as a supermarket checkout line recreated at sea. Mortorio itself sits among the park's most restrictive zones: landing on the island is banned outright, and navigation, anchoring and mooring of any kind of vessel are prohibited entirely. The park even installed a tarred cable across the water as a makeshift barrier to keep boats off the beach. According to Giudice, it gets cut with wire cutters on a regular basis, just so boats can push through to the shoreline anyway. Fines That Don't Function as DeterrentsPart of what's fueling the problem, park officials argue, is a basic economic mismatch: the people wealthy enough to own or charter a yacht large enough to reach these waters are often also the people least deterred by Italy's penalty structure. The organizer of the Mortorio "floating disco" faces a fine of €500, a rounding error against the cost of operating a superyacht for a single day. The gap becomes even starker in a cross-border comparison. Giulio Plastina, the park's director, has pointed out that a similar posidonia-anchoring violation at La Maddalena carries a maximum fine of around €51, compared to the roughly €100,000 in fines and damages a French court imposed on a catamaran captain for the same offense in the Calanques National Park near Marseille, and a separate case where a French maritime court fined the captain of the 37-meter superyacht Laurie I for anchoring in a protected posidonia zone near Corsica. Plastina has called Italy's penalty structure, essentially unchanged since the country adopted EU environmental directives without updating the underlying sanctions regime, simply not calibrated to the value of the boats actually breaking the rules. The Numbers Behind the RulesThe park does have a formal capacity framework in place: a daily cap of 700 vessels overall, split between 500 boats under 10 meters and 200 larger ones; charter-with-skipper permits capped at 450, with 75% of those reserved for La Maddalena residents; and a hard limit of 12 people per vessel regardless of size. The rules themselves have gotten stricter in recent seasons. The problem, as Giudice frames it, isn't the rulebook, it's enforcement. The park covers 47,000 hectares of water, and current patrol capacity, split between the park's own limited resources and Italy's Coast Guard and Guardia di Finanza, isn't remotely sized to match that footprint. What the Park Is Actually Trying to ChangeSome fixes are already underway for 2026: a regulated mooring-buoy system is being introduced at Cala Coticcio, one of the archipelago's most photographed and most pressured beaches, alongside similar buoy fields planned for Porto Madonna, Porto Palma and Cala Corsara. The system works on reservation: boats book a buoy in advance, pay for it, moor there instead of dropping anchor, and leave when their slot ends. The explicit goal is eliminating anchoring on posidonia entirely, permitting it only where the seabed is sandy. Giudice is also pushing for the park to establish its own dedicated ranger corps, arguing that oversight, not additional rulemaking, is the real unresolved problem. And she's signaled a tougher legal posture going forward: the park intends to formally join criminal and civil proceedings against the most serious offenders and seek direct financial damages, distinguishing between, in her words, "the small inflatable boat with two inexperienced people" and the large yachts running unlicensed charter operations, evading environmental fees, and treating the rulebook as optional. Looking to Corsica as a ModelGiudice has repeatedly pointed to Corsica, just across the Strait of Bonifacio, as proof that a different approach is possible. French authorities there enforce far stricter limits and far heavier penalties for the same violations, and, according to park officials, actually carry out the enforcement needed to make those rules mean something. Her stated goal for La Maddalena isn't closing the park to tourism entirely, but shifting toward a sustainability-first model: real caps, real enforcement, and fines that function as an actual deterrent rather than a rounding error. A Ten-Year WarningThe stakes, in Giudice's own framing, aren't abstract either. Without meaningfully strengthened enforcement, purchased buoy infrastructure, and fines that actually scale to the value of the vessels breaking the rules, she's warned that the archipelago's most fragile ecosystems could be irreversibly damaged within a decade. It's a warning echoed elsewhere in Sardinia this summer, as other marine protected areas along the island's coast report similar patterns: rules that exist on paper, enforcement capacity that doesn't exist in practice, and a tourism economy that's outgrown the infrastructure meant to protect the very landscape drawing people there in the first place.
