Formentera's anchorage permit system took effect in 2018, was tightened in 2020, expanded in 2023, and enters its eighth season in 2026 with an enforcement budget that finally matches the rules on paper. The Posidonia oceanica grass meadows that protect the famously clear water around Formentera are also the reason a yacht over 15 metres now needs a paid permit to anchor inside the Ses Salines de Ibiza y Formentera Natural Park. Fines for non-compliance run from €1,500 to €120,000 and the Balearic environmental authority enforced more than 200 infractions in the 2024 season alone.
This piece is the verified version of what the 2026 permit regime actually requires, which anchorages are permit-controlled, what costs what, the buoy field expansion at Espalmador, and the three operational errors charter captains continue to make. We are not arguing with the rules. They protect the water that made Formentera worth chartering in the first place. We are explaining how to comply without surrendering the day.
The Posidonia rule, briefly
Posidonia oceanica is a slow-growing seagrass endemic to the Mediterranean. It is the reason water clarity around the Balearics and parts of Sicily looks the way it does. It also dies when an anchor drags through it. The Govern Balear, the regional government of the Balearic Islands, designated Ses Salines as a protected zone in 1995 and progressively tightened anchoring rules from 2018 onwards.
The rule today: yachts may not anchor on Posidonia. They may anchor on sand patches within the protected zone, but only with a permit. The permit is purchased online through the Govern Balear portal. Pricing is per yacht per day and scales by length. Enforcement is by patrol boat and by satellite analysis of AIS tracks compared against the underwater habitat map.
What the permit costs
| Yacht LOA | 2026 daily permit fee | Notes |
|---|---|---|
| Under 15m | No permit required, anchoring still restricted to sand | |
| 15-20m | €30-€50/day | |
| 20-30m | €60-€120/day | |
| 30-40m | €120-€200/day | |
| Over 40m | €200-€400/day |
Rates are indicative as of May 2026 and confirmed against the 2025 published rates with the standard annual increase. The permit must be purchased in advance. Same-day permit issuance is no longer guaranteed at peak weekends.
Where the permits apply
The Ses Salines Natural Park covers roughly 130 square kilometres and includes the most-photographed anchorages on Formentera and the south side of Ibiza:
- Ses Illetes (Formentera west side). The signature white-sand beach with the run of beach clubs ashore. Permit-controlled. Sand bottom in patches between Posidonia meadows. Anchor only on sand.
- Espalmador (small island between Ibiza and Formentera). Permit-controlled. The buoy field expanded to 60 buoys in 2024. Buoys are bookable through the same portal.
- Cala Saona (Formentera south-west). Permit-controlled. Sand patches but tighter swing room.
- Es Calo des Mort (Formentera south-east). Permit-controlled. Small bay, limited capacity.
- Salinas and Cala Bassa (Ibiza south, inside the park). Permit-controlled. Cala Bassa in particular is heavily monitored.
Bays outside the park boundary do not require the permit. Cala Conta and Cala Comte (Ibiza west, just outside the park) do not require the permit but still have Posidonia and the captain still needs to drop on sand. The Es Cubells anchorage on the south Ibiza coast outside the park is unpermitted and is the conventional alternative when Ses Salines fills.
How the buoy system works
The Espalmador buoy field expanded from 28 buoys (pre-2023) to 60 buoys (2024 onwards). Each buoy is rated to a maximum LOA, posted on the buoy itself. Booking is through the Govern Balear portal up to 30 days in advance. Walk-up booking is possible if a buoy is unbooked at the start of the day, but in July and August this is rare.
The mooring buoy cost is bundled with the daily permit fee for the size class. A 30m yacht booking an Espalmador buoy in July 2026 pays roughly €180 for the day inclusive of the permit. Some captains continue to anchor outside the buoy field to avoid the booking lockup. The 2025 enforcement statistics show that anchoring on sand within the protected zone without a permit was the most-fined infraction of the season.
What charter clients actually see
A typical Ibiza-Formentera weekly charter spends one to two days at Formentera. The day shape on a busy August Saturday at Ses Illetes:
- 09:00: Captain confirms permit is active for the day
- 10:00 to 11:00: Anchor on a sand patch, often outboard of the inner anchorage where the better sand is taken
- 11:00 to 16:00: Tender ashore to Beso Beach, Juan y Andrea, or Tanga (the three named beach clubs)
- 16:00: Reposition or stay
- 18:00 onwards: Move to Espalmador for the night if a buoy is booked, or return to Ibiza
The constraints are real. The day is still excellent. Captains who plan ahead and book permits on Wednesday for a Saturday charter do not have problems. Captains who try to wing it in late July hit the enforcement issue.
What brokers oversell
The "we just drop and go" claim. A small number of brokers continue to market Formentera as "the anchorage day you remember" without mentioning the permit. The honest version is: the day is a planned, paid, scheduled anchorage day with restaurant bookings, a permit code, and a buoy reservation. None of that ruins the day. Pretending the constraints do not exist sets the wrong expectation.
The "we know a guy" route. A handful of operators continue to claim they can secure a permit "through their contact at the port authority" for an extra fee on the APA. The permit system is an online portal accessible to anyone. There is no contact required and no premium service available. If a broker is charging a permit-arrangement fee, it is markup, not service. Push back.
The west-Formentera lunch crawl. The "lunch at Beso Beach, drinks at Juan y Andrea, dinner at Tanga" sequence is sold by 90 percent of brokers running Ibiza-Formentera weeks. All three restaurants are on the same beach run, all three are crowded in August, and all three book out by April for the peak weeks. If the broker has not booked the table at proposal stage, the client will eat aboard or at a fallback. Confirm restaurant bookings in writing before signing.
What needs work
Three things. The permit system should publish a 2026 fee table in a single PDF on the Govern Balear site rather than the current scattered communications. The opacity of the fee table is what allows brokers to add coordination fees that are not justified.
The Espalmador buoy field, while expanded, still does not match peak weekend demand. We would prefer the Govern Balear publish demand statistics so charter operators can plan around peak fill days.
The enforcement rules should be communicated to the charter client at booking, not at embarkation. We have seen MYBA proposals in 2025 that include the Posidonia rule as a single line in the appendix, after 12 pages of itinerary. Clients booking a €200K week deserve to know the rule before they sign.
The verified Ibiza-Formentera 7-day route
For a complete 7-day week including the Formentera permit constraints, see our Ibiza-Mallorca 7-day Balearic loop. The short version: two nights at Formentera (one permit day, one Espalmador buoy night), two nights at south-west Ibiza, one night at Cala Salada, one night at San Antonio bay, and one night back at Marina Ibiza. Permit days are pre-booked. Buoys are pre-booked. The week works.
Other Balearic anchorages worth knowing
Outside the Ses Salines Natural Park, several Balearic anchorages remain unpermitted in 2026:
- Cala Comte and Cala Conta (Ibiza west). Sand and rock, anchor on sand, no permit.
- Cala Salada (Ibiza north-west). Sand, no permit.
- Cala Mastella (Ibiza north-east). Sand, no permit.
- Cabrera National Park (south of Mallorca). Different permit regime, buoy-only access, bookable.
- Mallorca north coast bays (Sa Calobra, Cala Tuent). No permit, anchor on sand.
The Mallorca anchorages and Cabrera are arguably the better value-for-effort destinations in the Balearics in 2026 because of the lower enforcement load. We recommend mixing them into the week rather than spending three days at Formentera and one at Mallorca, which is the conventional broker itinerary.
Costs and rates
Indicative weekly charter rates for a Balearic-base, peak season, as of May 2026:
| Yacht size | Peak weekly rate |
|---|---|
| 24-30m motor | €60K-€100K |
| 30-40m motor | €110K-€180K |
| 40-50m motor | €200K-€350K |
| 50m+ motor | €400K+ |
Plus 30-35 percent APA and Spanish VAT structure that applies to charters within Spanish waters. The matricula tax exemption that historically penalised non-EU-flagged charter yachts has been clarified and is no longer the issue it was pre-2014. Confirm with the broker that the yacht's flag and Spanish charter license are in order.
FAQ
Do you need a permit to anchor off Formentera? Yes for yachts over 15 metres within the Ses Salines protected area. Cost is roughly €30 to €400 per day depending on size.
What happens if you anchor without a permit? Fines from €1,500 to €120,000 under Balearic environmental law. Enforcement has increased materially.
Are the Formentera anchorages still worth visiting? Yes. The day takes more planning than it did in 2017 but the bays themselves are calmer because of the rules, not less worth visiting.
Can my broker arrange the permit? Yes. The broker should include the permit fee in the APA, not as a separate "coordination" charge. Push back on bundled coordination fees.
Are there alternatives to Formentera if the permits are too constrained? Yes. The Mallorca north coast, Cabrera, and the unpermitted Ibiza-west anchorages give a comparable day without the booking burden. We recommend mixing them into the week.
Verdict
The Formentera permit system is the model the rest of the Mediterranean will copy. The water is calmer for it. The day is more planned than it was. Book the permits, book the buoys, book the restaurants, and the week works. Pretend they do not exist and the trip suffers in ways the broker cannot fix.
