Sa Nitja

Sa Nitja's bay sits sheltered behind a cape on Menorca's north coast, calm on most days even when the sea beyond the headland is not. In the shallows, posidonia covers the bay floor in dense, healthy beds — the product of decades of full protection under the North Marine Reserve. Rocky sections along the perimeter reach 8–25 metres, hosting groupers, conger eels, and moray eels in concentrations that reflect the reserve's documented biomass recovery. The adjacent islet of S'Illa des Porros provides a wall from 8 metres down to around 30. With a hard cap of two dives per day across all divers in Sector 4b, the site is almost always yours alone — a guarantee of solitude no other Menorcan dive can offer.

Sa Nitja is the only site in the current Menorca catalog requiring prior authorization — a level of access control that, in practice, means near-guaranteed solitude in the most-protected bay on the island. The Sector 4b cap of two dives per day total filters out spontaneous visitors entirely; the result is one of the Mediterranean's most genuinely protected environments still open to recreational divers. The archaeological context adds a dimension absent from every other Menorca site. The Roman harbour of Sanisera was established here in the 2nd century BC, and the headland remains an active archaeological site today. Migrating stingrays pass through from April to June, and the biomass density here — the reserve holds hundreds of documented benthic species — consistently exceeds what comparable unprotected Menorcan sites offer.

Prior authorization from the reserve management body is mandatory for Sector 4b. Book through a Fornells dive centre; most operators familiar with this reserve handle the authorization on your behalf — it is separate from and in addition to the standard day permit (EUR 5.24/day). The two-dives-per-day cap covers all divers in the sector combined, not per person: if it is already used when you arrive, the dive does not happen that day. Cave diving is prohibited throughout the North Marine Reserve. The posidonia meadow and main reef sections (3-18m) are accessible to OW divers; the S'Illa des Porros wall reaching 30m is recommended for AOW and above. Sa Nitja's north-coast exposure makes it among the first sites to cancel in strong Tramuntana conditions — have a backup site ready and check the forecast the morning of the dive.
