Cabrera: the National Park South of Mallorca — Permit, Quota and Buoys
Sailing to the Cabrera archipelago from Mallorca: mandatory permit, a 50-boat daily quota, mooring buoys only, and the best time to book a slot.
South of Mallorca, a short hour's sail from Palma or Colonia de Sant Jordi, the Cabrera archipelago remains one of the Balearics' best-kept secrets: near-improbably blue water, an untouched seabed, and access deliberately capped to keep it that way.
Spain's first marine national park
Closed to the public for decades as a military zone, the archipelago became Spain's first maritime-terrestrial national park in 1991, before being listed as a Ramsar wetland and folded into the Natura 2000 network. That long closure is a big part of why Cabrera's seabed ranks among the best preserved in the western Mediterranean today — a sharp contrast with Mallorca's own, far busier, summer coastline.
A strict quota: 50 boats a day
Access is neither free nor automatic. The park caps the number of private vessels allowed in at any one time to roughly 50 boats a day, across all categories. A navigation permit is required before even entering the park's waters, separate from any mooring permit — both are requested online through the park's administration, ideally weeks ahead in high season. Skip the permit and the smart move is to skip the stop entirely: enforcement is real, and so are the fines.
No anchoring, buoys only
Another rule that catches sailors used to the rest of the Mediterranean off guard: dropping anchor is forbidden inside the park, barring an emergency, to protect its posidonia seagrass meadows and rocky seabed — the same principle covered in our marine protected areas guide. Boats moor exclusively on the park's own buoys: free day buoys, first-come-first-served with no overnight stays allowed, and paid mooring buoys, bookable for one or more nights depending on the season. The rule tightens further in July-August: only a single night is allowed on a mooring buoy, and staying overnight at the island's small quay isn't an option. Our anchoring etiquette guide still applies for the rest of the trip, once you're back outside the park.
What protection has actually changed underwater
The point of these restrictions shows up very concretely below the surface. A study carried out in the archipelago compared the demographic structure of the dusky grouper (Epinephelus marginatus), an emblematic fish long heavily fished across the Mediterranean, between Cabrera's protected zones and nearby waters open to fishing: individuals were significantly more numerous and older wherever protection was actually enforced (Reñones, Goñi, Pozo, Deudero & Moranta, 1999, see the study on Google Scholar). Snorkelling over the archipelago's drop-offs, what you're seeing isn't just bigger fish — it's evidence that a genuinely enforced protected area keeps producing a measurable effect decades after it was created.
An archipelago worth the trip beyond diving
The main island keeps a small 14th-century fort and a single seasonal restaurant near the harbour, with nothing else built up — it's precisely that lack of development that makes the stop worthwhile. Cabrera also hosts one of the world's largest breeding colonies of the Balearic shearwater, an endangered seabird that nests in the archipelago's cliffs — one more reason several stretches stay closed to landing during the breeding season. The monk seal, long gone from the Balearics today, once frequented the coastal caves here — a reminder of what a sea free of fishing pressure could still support a century ago.
Book the slot first, the boat second
The one thing to remember before building a Balearics itinerary: Cabrera gets booked first, well before the boat itself. In July and August, navigation slots and buoys sell out weeks in advance, and a last-minute refusal means rethinking the whole day. A professional operator knows the process and can sometimes handle it on your behalf — ask at booking time, not on departure morning. Outside the season (April-June, September-October), slots stay far easier to secure, with equally clear water and far fewer boats on the buoys.
Planning the trip from Mallorca
The crossing is usually organised from Palma or from Colonia de Sant Jordi, closer to the archipelago, as a full day out. A fast RIB (€200-600 a day) covers the round trip easily in calm weather, while a sailboat or catamaran allows for a longer stay and an overnight on a buoy where the permit allows it. Bring a mask and fins: the water around the day buoys ranks among the clearest in the archipelago.
- Apply for the navigation permit (and mooring permit if needed) weeks ahead in high season.
- Plan around calm weather for the crossing: the stretch between Mallorca and the archipelago stays exposed.
- Compare departure options from Palma and Alcúdia to pick the most convenient base for your dates.
