Good holding
Recommended Anchor Alarm Radius
80m
80m in 5–10m on volcanic sand/mud. Good holding in typical conditions. The W/SW exposure is the vulnerability — in Libeccio or Maestrale, swell wraps around Cape Miseno and the bay becomes untenable. Monitor forecasts; depart before W/NW wind builds above F4.
About This Anchorage
Cape Miseno (Capo Miseno) is the dramatic volcanic headland at the southwestern tip of the Campi Flegrei, where the Gulf of Pozzuoli meets the outer Bay of Naples. In antiquity this was the base of the Roman Western Imperial Fleet — the Portus Julius (partially submerged) and the ancient Miseno harbour are now important archaeological features. The cape was where Pliny the Elder launched his rescue mission during the eruption of Vesuvius in 79 AD (and died in the attempt). The Baia di Miseno to the north provides a sheltered anchorage in SW-facing conditions, with the volcanic crater lake of Lago di Miseno immediately behind the cape (visible but not directly accessible from the anchorage). The setting is historically extraordinary — approaching Cape Miseno from seaward, you sail the same water as Roman triremes.

Setting Your Anchor
Anchoring on Posidonia oceanica meadows is prohibited throughout Italian waters and is actively enforced — fines range from €500–€3,000. Always snorkel to verify the bottom is clean sand before setting. In the AMP Parco Sommerso di Baia (Pozzuoli area), Zone A prohibits all entry, Zone B requires mooring buoys only, and Zone C permits limited anchoring on sand only. Check AMP zone maps before anchoring anywhere near Baia or Cape Miseno.
Anchoring Rules
- Anchoring fee
- Free. Some mooring buoys near village (fee applies).
- Maximum stay
- 3 days
- Permit required
- No
- Mooring buoy fee
- Check locally for current buoy fees.
Restrictions: Standard Italian maritime rules. No anchoring on Posidonia. Military restrictions may apply around the cape itself (check NOTAM and local notices — the cape area has some military installations). Hydrothermal activity: avoid anchoring directly over visible seafloor gas vents.
Hazards
- !Campi Flegrei volcanic activity: The entire area is within the Campi Flegrei caldera — hydrothermal vents, gas emissions, and occasional seismic swarms occur; monitor INGV Osservatorio Vesuviano alerts at ov.ingv.it
- !W/SW exposure: Swell from Libeccio or Maestrale wraps around Cape Miseno into the bay; in any W wind above F4, vacate the anchorage
- !Fishing boat traffic: Active small-boat fishing fleet using the bay — especially at dawn and dusk; maintain clearance from net areas
- !Military area proximity: Some areas around Capo Miseno have historic and possibly current military use — observe any posted restriction notices
Skipper's Tips
- →Climb to the top of Capo Miseno (lighthouse) for one of the finest panoramic views in Italy — the Gulf of Naples, Vesuvius, the islands of Procida, Ischia, and Capri, and the Sorrentine Peninsula all in one frame
- →The Lago di Miseno (volcanic crater lake visible from the cape) is the site of the ancient Roman naval arsenal — tour guides from Pozzuoli offer boat tours of the partially submerged Roman installations
- →Cape Miseno mussels (cozze di Baia) are farmed on ropes in the gulf and are among the finest in Italy — buy directly from the mussel farmers who work the bay; they sell at the village quay most mornings
- →For history enthusiasts: the combination of Baia (submerged Roman city, 2nm N), Miseno (Roman fleet base), Lago d'Averno (Hades entrance), and Cumae (first Greek colony in Italy, 5nm N) makes this the richest Classical-era anchorage ground in the Mediterranean
Facilities
Several restaurants and trattorie in Miseno village — local seafood, particularly mussels (cozze di Baia) farmed in the nearby gulf.
Nearest provisions: Miseno village (0.5nm)
Best Months & Season
May, June, September, October
April–October. The Campi Flegrei area is fascinating in all seasons but sailing conditions are best May–October. November–March: Libeccio/Scirocco more frequent; overnight only for experienced crews.

In the Gulf of Naples, the Scirocco can build swell rapidly and ferry wash is constant. Safety Anchor Alarm monitors your GPS position continuously — alerting you the moment your anchor starts to drag.
