My first Greek island hop from Athens — what nobody tells you

I booked the ferry from Piraeus two days before I needed it, which everyone who knows Greece told me later was cutting it extremely close in June. I got the last cabin on a midnight departure to Santorini. This was the first of several things about island hopping that I had to learn through direct, slightly stressful experience.

The second thing I learned was that Greek island hopping from Athens is not a single experience. It is dozens of different experiences depending on which islands you choose, which direction you go, how much you care about nightlife versus hiking versus swimming versus just sitting at a harbour café watching boats come and go. There is no single correct answer, and most advice you’ll get is someone telling you their version of the correct answer as though it were universal.

Here, for what it’s worth, is my version — which starts with a mistake and ends on a car-free island that remains the best thing I’ve seen from a Greek ferry deck.

The Piraeus morning

Piraeus is not beautiful. It is the working port of a working city — enormous, slightly chaotic, full of the vehicular and commercial business of actually getting cargo and people between islands and mainland. The ferry terminal is a long strip of different gates, each serving different islands and operators, and if you arrive without knowing which gate number your ferry leaves from you will walk considerable distances with your bag in the wrong direction.

Get the gate number from your ticket before you arrive. Gate E1 is for the Cyclades — Santorini, Mykonos, Paros, Naxos. Gate E5 is for the Saronic islands — Hydra, Spetses, Aegina. They are not near each other.

High-speed catamarans cut crossing times roughly in half: Athens to Santorini is 5 hours instead of 9 on the fast ferry. Worth the price difference on a tight schedule; less critical if you’re happy to be on a large slower ship where you can sleep or sit on deck.

Santorini first — the honest take

I spent three days on Santorini and can confirm it is exactly what it looks like in photographs — the blue domes, the white walls, the caldera views, the sunsets over Oia that cause enormous crowds to gather with raised phones.

It is also very expensive, very crowded in late June, and somewhat challenging to experience beyond the postcard unless you make specific choices. The villages away from Fira and Oia — Emporio, Pyrgos, Megalochori — are noticeably calmer and give a better sense of what Santorini actually is beyond its Instagram surface.

The wine here is genuinely interesting: the volcanic soil produces an indigenous white variety called Assyrtiko that is unlike any wine you’ve had elsewhere — mineral, high acid, almost salty. Try it with octopus at a restaurant not on the caldera edge and you’ll pay half as much and enjoy the food twice as much.

For a guided version that gets you the wine, the view, and the village context without the solo logistics, the Santorini highlights wine tasting and Oia sunset tour hits the essential stops without the queues and navigational chaos of doing it alone.

The pivot to Hydra

From Santorini I took a ferry to Hydra — an island in the Saronic Gulf, much closer to Athens, accessible by high-speed hydrofoil in about 90 minutes from Piraeus. The contrast is complete.

Hydra has no motor vehicles. Not a single one. Transport on the island is by donkey, boat or walking. The harbour town is a semicircle of grey-stone mansions rising steeply up the hillside, the port itself animated by fishing boats and water taxis and the smell of the sea. There are no major archaeological sites, no famous sunsets, no Instagram landmarks. What there is: swimming off rocks, walking into the hills, eating at tables on the quay, a very pleasant absence of noise.

This was where the island-hopping trip stopped being an itinerary and became a holiday. I stayed for four days instead of two, swam every morning from a rock platform accessible by a 20-minute walk from the port, and ate lunch at the same taverna every day because the owner started giving me the daily special before I asked.

A day trip version — if Athens is your base — is also genuinely worthwhile. The Hydra full-day swimming trip from Athens includes the ferry and gives you a day on the island with swimming and time on the harbour. Even a day is enough to understand why people fall for the place.

What I’d tell anyone planning their first island hop

Go to fewer islands for longer. The urge to visit five in ten days produces a holiday of ferry terminals and luggage-dragging and never quite settling. Three islands in two weeks is a more honest pace; two islands is fine.

The Saronic islands — Hydra, Spetses, Aegina, Poros — are underrated by most first-time visitors and are significantly less crowded than the Cyclades while being closer to Athens and served by more frequent ferries. They are also the places where Athenians themselves go on weekends, which tells you something.

Check the wind. The Meltemi blows hard across the Aegean in July and August, causing smaller islands to be cut off for days at a time and making sea conditions uncomfortable. Build flexibility into your schedule.

For the broader island context from Athens, the Greek islands from Athens guide covers the Saronic islands, Cyclades and day trip options in more detail. And the day trips section has a full breakdown of what’s reachable for a one-day excursion versus what requires an overnight.

My first island hop ended back in Piraeus on a Tuesday morning with a ferry-tan on my arms and a strong conviction that I’d been doing holidays wrong for years. The Greek islands operate at a particular register — unhurried, beautiful, occasionally maddening in their logistics, but ultimately very good at reminding you that the point of a holiday is to be somewhere completely.

Go. Book the ticket. Learn which gate.
