The Saronic Gulf by boat

The single most useful thing to know before you book anything off this coast: there are two completely different boat days here, and people regularly book the wrong one. A private sunset cruise is a half-day from the small Marina of Anavyssos, on the southern Athenian Riviera about 50–55 km / an hour’s drive down the coast road from Athens Airport — turn up, a skipper does the rest. A sailing charter — bareboat, skippered or fully crewed — is a different animal, run from Olympic Marine at Lavrion on the east coast of the Attica peninsula (the operators put it ≈ 25–30 min from the airport), and a bareboat needs sailing certificates aboard. One is an evening; the other can be a week into the Cyclades. And note the boundary with the scheduled ferries: a charter means you hire the boat; for ordinary island-hopping on a timetable you want the Lavrio ferries, not a charter at all.

An evening on the water — the sunset cruises

For a few hours afloat with no planning, this is the easy one. The most convenient choice is a private cruise straight from the Marina of Anavyssos: out along the Riviera, into a sea cave, an anchor for a swim, then the Temple of Poseidon at golden hour. If you’d rather make a whole day of it — and don’t mind sharing the boat — a full-day group cruise runs the same coast from Varkiza, a little to the north.

• Azure Day Cruises — private sunset to Cape SounioFrom the Marina of Anavyssos

  The most convenient option, and the one most people want: a roughly half-day, fully private cruise that leaves the Marina of Anavyssos, runs along the Riviera to the Arsida sea cave, anchors off Patroklos Island for a swim, then carries on to watch the Temple of Poseidon turn gold at sunset before bringing you home. English-speaking skipper; welcome snacks, soft and alcoholic drinks, snorkelling gear and beach towels aboard. Priced by private quote rather than per head.

• Athenian Riviera Escapes — “Sounio Sun & Sea”Full-day group · from Varkiza

  A full-day group cruise — roughly mid-morning until after sunset — that departs Varkiza Fishing Port, ≈ 20–25 min north of Anavyssos, rather than the local marina, so it is a longer day with more people aboard. It runs the length of the Riviera past Lagonisi, Saronida and Anavyssos, anchoring at Arsida and Patroklos before the temple at Sounio Bay, sunset included. Reckon on roughly €150–200 per person with meals and drinks, but treat that as season-dependent and confirm the current rate when you book.

Patroklos & Arsida — where you swim

The cruises anchor at the same two spots. Patroklos — also called Gaidouronisi, “donkey island” — is an uninhabited island lying about 850 m off the coast almost opposite Cape Sounion, rising to a steep ≈ 240 m, with clear water that makes it the natural swim-and-snorkel stop on any trip down this coast. Nearby Arsida is a small islet known for its sea cave and the same glassy water. Neither is reachable by road; the only way to swim off them is from a boat.

The temple, from the sea

The set-piece is the Temple of Poseidon. On land, the cape at sunset is the honest truth of it: coach parties, a wall of phones, a scramble for the same photograph everyone else is taking. From the water it’s a different evening — the temple on its headland turning gold as the sun drops into the Aegean, a breeze, and room to just watch it. From the Anavyssos marina the round trip is short enough that you’re back ashore before the light has fully gone. (If you’d rather take it in from the headland itself, the Cape Sounion sunset guide has the timing — that page also covers getting to the cape without a boat.)

Do you need a licence? — taking a boat out yourself

Start here, because it decides what kind of day is even open to you. You don’t always need a skipper or a licence. In Greece you can usually hire and drive a small motorboat with no boating licence at all, as long as the engine is 30 hp or less — you must be over 18, carry ID, and stay within about three nautical miles of shore. Anything more powerful needs a valid licence. That makes a license-free boat a fine way to potter the sheltered Saronic coast and the islets just off it, but it is not the boat for a long open crossing. Local rentals such as Sun Sea Deck at Palaia Fokaia keep a handful of small boats and RIBs, some licence-free; license-free self-drive boats can also be hired in Anavyssos itself. Always confirm the exact terms, engine size and area limits with the operator before you pay — the rules above are the general shape, not a guarantee.

A full bareboat yacht is a different bar. Greek port authorities typically want at least one certified skipper aboard — over 18, holding an ICC or a recognised national equivalent — plus a second competent crew member, and the certificate paperwork usually has to reach the charter base a few weeks ahead. If you don’t hold those, you are not shut out: the same yachts go out skippered or fully crewed. Requirements shift, so check the charter company’s current list before you commit rather than assuming your home licence will be accepted.

When to go — and when to stay ashore

The water is warmest from late spring through early autumn. The thing to plan around is the meltemi, the dry north wind that builds across the Aegean in July and August and is usually strongest by mid-afternoon; mornings tend to be calmer, and shoulder-season days are gentler all round — the best-time-to-visit guide has the season-by-season detail. Book ahead in peak summer — the good skippered boats go early. If anyone aboard is prone to seasickness, a short Riviera sunset cruise is a kinder first outing than a long open crossing, and an afternoon with the meltemi up is the one to swap for a morning slot.

The serious charters — Olympic Marine, Lavrion

For a real sailing holiday, the base is Olympic Marine at Lavrion, on the east coast of the Attica peninsula and the area’s primary charter marina — distinct from the public ferry port nearby. It is a genuine full-service yard: 680 berths, hard-standing for hundreds of boats, three travel lifts (the largest rated 350 tonnes), a fuel station, repair facilities and 24/7 security, and it has flown the Blue Flag every year since 2000. From here the Cyclades come quickly — Kéa, the first island, is only about 16 nautical miles out — which is why operators call Lavrion the gateway to the islands: Kéa, Andros, Tinos, Mykonos, Paros and Naxos one way, the Saronic Gulf the other. The operators put it ≈ 25–30 min from Athens Airport.

Several established fleets charter sailing yachts and catamarans from the base — bareboat (you take the helm), skippered (someone sails for you) or fully crewed.

• Istion YachtingDedicated Lavrion base

  A useful anchor example: runs bareboat, skippered and crewed yachts from its own Lavrion base, and frames the marina as the gateway to Andros, Tinos, Mykonos, Paros and Naxos. Several other established fleets — among them Hermes, ARCHON, Olympic and Dream Yacht Charter — work the same base with sailing yachts and catamarans, bareboat through fully crewed. Compare a couple on dates and boat size rather than taking the first quote; operators come and go, so check current availability.

With the right papers you can take a bareboat and string a week through the western Cyclades — Kéa first, then Kythnos and Serifos — sleeping aboard. Honestly, though, if sailing itself isn’t the point and you just want to set foot on an island, you don’t need a charter at all: the Lavrio ferries do it on a timetable for a fraction of the cost, with a day on Kéa the gentlest version. Charter the boat when the boat is the holiday; take the ferry when the island is.

What a day aboard is like

A skippered day usually starts mid-morning and runs to early evening: an hour or so under sail to a bay, a long anchor for swimming and lunch, then the run home with the wind behind you. You bring swimwear, a hat and sunscreen, and a layer for the breeze — not much else. Most boats carry water, shade and a swim ladder, and a skippered charter often includes a simple lunch aboard or a stop at a harbour taverna. It’s an unhurried day rather than a thrill ride: the point is the swimming, the quiet coves the road can’t reach, and the long view back at the coast. Children and non-sailors are usually completely at home on it.

The one-line version: want an evening, no paperwork, minimum fuss — book the private Anavyssos sunset cruise. Want the boat to be the trip and you can crew it — bareboat from Lavrion. Just want to reach an island — skip the charter and take the ferry. And if the meltemi is up in the afternoon, take the morning slot or stay ashore and swim off the coast instead.

Operators, sailings and prices shift season to season — treat the specifics as a starting point and confirm when you plan. Last checked June 2026.
