Five coves top our list of Ibiza beaches only accessible by boat: Atlantis (Sa Pedrera), Cala Llentrisca, Ses Balandres, Cala Xuclar and Cala d'en Serra. None of them has a proper road in, and one of them — Atlantis — lost its land access altogether when the clifftop path was fenced off in 2025. We anchor at all five through the season with our NAVAN S30, so this guide covers what the usual lists leave out: where to drop the hook, which swell direction spoils each cove, and the hour of the day each one is at its best.
Ibiza beaches only accessible by boat: the five that earn the trip
Ibiza has plenty of "secret" beaches with a car park hiding behind the pines. These five are different. Getting there means a hull under you — or, at best, a scramble most people sensibly refuse. That is exactly why they still feel the way the island must have felt decades ago.
Atlantis (Sa Pedrera de Cala d'Hort)
An old stone quarry carved into the cliffs of the south-west coast: angular platforms, sea-worn carvings, rock the colour of honey. Since the path down was fenced off in 2025, the boat is genuinely the only way in. There is no sand to step onto — we anchor just off the rocks on a clear patch and you swim the last stretch, which is half the fun. Atlantis lies open to west and south-west swell, so it is strictly a calm-day cove; on the right afternoon the low sun sets the quarry walls glowing and the water turns to glass. We usually pair it with our Es Vedrà route, because the rock rises just around the corner.
Cala Llentrisca
A pebble crescent tucked behind Cap Llentrisca, with a row of weathered fishermen's boathouses and not a single sunbed. The only land access is a long, rough footpath from Es Cubells, so even in August you may share the bay with just a couple of other boats. Sheltered from the northerly winds, it specialises in glassy mornings: arrive early and, once the rattle of the anchor chain fades, the only sound left is water moving over pebbles. The seabed is a posidonia meadow broken by lanes of clear sand — our skipper knows where they run, so the anchor holds without touching the protected seagrass.
Ses Balandres
The wildest of the five, hidden beneath towering cliffs on the north-west coast near the sea arch of Ses Margalides. On land it is reached — barely — with ropes down the cliff face; from the water it is a straightforward approach on a settled day. Any west or north-west swell wraps into the cove, so we only plan it when the forecast is genuinely quiet. Aim for midday, when the sun finally drops onto the cove floor and the water lights up between the boulders. The sound of our engines echoing off that wall of rock is a moment guests still mention on the cruise home.
Cala Xuclar
A pocket-sized fishing cove near Portinatx, on Ibiza's northern tip: a strip of pebbles and coarse sand, a handful of boat huts and remarkably clear water. Officially a rutted dirt track finds its way down; in practice, arriving from the sea is how the cove is meant to be seen. It faces north, so we save it for days when the wind blows from the south and the north coast turns to glass. Come in the morning and take the snorkelling gear straight off the boat — the rocky edges of this cove are among the liveliest we know for fish.
Cala d'en Serra
A deep, narrow inlet in the island's north-east corner, guarded by green ridges and the concrete skeleton of a hotel that was never finished — strangely photogenic, and the reason the cove was never developed. The track down is punishing enough that most hire cars turn around. Inside, the water is sheltered from almost everything except a north-easterly, and the snorkelling along the rocks is excellent. We like it late in the day, when the light falls down the valley and the busy beaches of the east coast feel very far away.
How we reach them from Santa Eulalia
Our NAVAN S30 departs from Marina Santa Eulalia, Berth H17 on the east coast, and a full-day charter gives you eight hours on the water, typically 10:00 to 18:00. One piece of honest advice: don't try to tick off all five coves in a single day. We split them into two natural runs:
- The north run: up past the island of Tagomago — about twenty minutes from our berth — then along the wild north coast to Cala Xuclar and Cala d'en Serra, with Ses Balandres as an option on a very calm day.
- The south-west run: south past the silhouette of Dalt Vila and around the island's tip to Cala Llentrisca, Atlantis and Es Vedrà.
Either way a professional skipper is at the helm — you never need a boat licence — and snorkelling gear and a Bluetooth sound system are already on board. If you are weighing up the budget, we have broken down what a private day charter in Ibiza really costs, season by season.
Anchoring, swell and timing: the details that decide the day
Three things matter more at these coves than at any beach with a road:
- Anchor on sand, never on seagrass. The posidonia meadows are protected — and they hold an anchor badly anyway. Our skipper reads the bottom and picks the clear patches.
- Swell beats wind. A cove can be windless and still rolly if yesterday's swell is running into it. We check the direction every morning and choose the coast that is sleeping.
- Time of day changes everything. Llentrisca and Xuclar are morning coves; Atlantis and Cala d'en Serra repay the afternoon light.
Tell us which of the five matters most to you when you book, and our skipper will build the day around the sea state. That flexibility — deciding at the helm, not at a ticket desk — is exactly what a private boat is for.
