Alonissos keeps appearing on lists of Greek islands to watch. Travel forecasters have started naming it among the emerging destinations for 2027, driven by the shift towards slow, experience-led travel: hiking, diving, small tavernas, no queues. It is a fair call. Alonissos genuinely is one of the quietest inhabited islands in the Aegean, and it sits inside the largest marine protected area in the Mediterranean.
But there is a practical fact that shapes every Alonissos itinerary, and most articles skip past it: the island has no airport. If you are flying, you are landing on Skiathos and taking a ferry, or flying to a mainland airport and taking a much longer one from Volos. So the real question is rarely "Skiathos or Alonissos" in the abstract. It is: where do you sleep, and how much of the other island do you want?
Key Takeaways
- Alonissos has no airport. Skiathos (JSI) is the practical gateway, with direct flights from nine UK airports on Jet2 plus German and Nordic routes.
- Skiathos has over 60 beaches, a full restaurant and nightlife scene, and a wide range of villas. Alonissos has quiet coves, hiking trails, world-class diving and far fewer facilities.
- The National Marine Park of Alonissos covers roughly 2,250 km², the largest marine protected area in the Mediterranean, and protects the Mediterranean monk seal.
- The Peristera shipwreck near Alonissos became Greece's first underwater museum — a genuine reason to visit for certified divers.
- For most one-week trips, basing on Skiathos and taking Alonissos as a day or overnight trip gives you both without the logistics tax.
Skiathos vs Alonissos: The Short Verdict
If you want a holiday that works for a mixed group with minimal friction, choose Skiathos. If your idea of a good week is walking, diving and reading with almost nobody around, choose Alonissos — but expect to route through Skiathos anyway.
The two islands are only about 40 km apart, yet they feel like different decades. Skiathos is roughly 47 km², compact enough that nothing is more than a 20-minute drive, with an international airport, a busy town, dozens of tavernas and a bus route that runs every 10 to 15 minutes in summer. Alonissos is around 64 km² with a population of roughly 2,700, one main port at Patitiri, a beautiful restored hilltop Chora, and long stretches of coast where the only sound is cicadas.
Neither island is trying to be the other. What matters is being honest about the trade-off: Alonissos buys you quiet at the cost of convenience, and Skiathos buys you convenience at the cost of some solitude in July and August.
Access and Getting There: The Deciding Factor
Skiathos has the only airport in the Sporades, and that single fact determines how most people reach Alonissos.
Skiathos airport (JSI) receives direct summer flights from nine UK airports on Jet2 alone, plus routes from Germany, Austria and the Nordics, and 30-minute domestic hops from Athens. Alonissos has no airport and no realistic prospect of one. Your options are:
| Route | Typical journey | Notes |
|---|---|---|
| Fly to Skiathos, ferry to Alonissos | Flight + roughly 1h–1h45 at sea | Fast ferries often call at Skopelos en route |
| Fly to Volos or Athens, ferry from Volos | 3–5 hours at sea | Fewer sailings, longer day, cheaper flights |
| Athens flight + Skiathos ferry | Adds a domestic leg | Useful in shoulder season when direct flights thin out |
Fast ferry fares between Skiathos and Alonissos typically run around 20 to 40 EUR return depending on operator and speed, with several sailings a day in high summer and a noticeably thinner timetable from late October. Our guide to getting to Skiathos covers the flight and ferry combinations in detail, and the full Alonissos from Skiathos guide walks through the day-trip timings.
The practical implication: if you stay on Alonissos for a week, you will spend two travel days on ferries and probably an overnight on Skiathos at one end. If you stay on Skiathos, you can visit Alonissos on a whim when the weather looks right.
Beaches, Nature and the Marine Park
Skiathos wins on beach quantity and sand; Alonissos wins on water quality, wildlife and having a cove to yourself.
Skiathos packs over 60 beaches into 44 km of coastline, the majority sandy: Koukounaries with its pine forest and lagoon, Achladies and Troulos for families, Vromolimnos for watersports, Lalaria for drama. Almost all of the south coast is on a single bus route. Our Skiathos beaches guide breaks them down by what you actually want from a day.
Alonissos plays a different game. Its beaches are mostly pebble and white shingle — Chrysi Milia, Kokkinokastro, Leftos Gialos, Agios Dimitrios — with water clarity that is startling even by Aegean standards. That clarity is not an accident. The island sits at the centre of the National Marine Park of Alonissos and the Northern Sporades, which covers roughly 2,250 square kilometres and is the largest marine protected area in the Mediterranean. It was established to protect the Mediterranean monk seal, one of the most endangered marine mammals in the world, and its inner zones around uninhabited islets such as Piperi are closed to visitors entirely.
The park is why Alonissos feels different underwater. Marine life is visibly healthier than at most Aegean sites, and licensed boat trips through the outer zones — past Kyra Panagia, Gioura and Peristera — are among the better wildlife excursions in Greece.
Diving: Alonissos's Genuine Advantage
The Peristera shipwreck, a fifth-century BC cargo vessel lying off the neighbouring islet of Peristera, opened as Greece's first underwater museum. Certified divers can visit it on guided dives from Alonissos operators, with dry-land visitor facilities for non-divers. There is nothing comparable on Skiathos, which has decent recreational diving but no protected wreck of that significance. If diving is the point of your holiday, Alonissos is the correct answer.
Food, Nightlife and Infrastructure
Skiathos has the range; Alonissos has the atmosphere but far fewer options.
Skiathos Town has well over a hundred places to eat, from waterside fish tavernas to modern Greek kitchens, plus a genuine late-night scene along Papadiamantis street and the Old Port. Supermarkets, pharmacies, a health centre, car hire, and reliable services all exist at scale. Our restaurant guide covers the ones worth booking.
Alonissos has excellent food — Patitiri and the Chora both have tavernas that punch well above the island's size, and the local speciality is honest, seasonal and often fish-led. But the choice is limited, several places close by early October, and nightlife essentially means a slow drink under bougainvillea. Car hire and taxis exist but stocks are small in August. If you need a chemist at 10pm or a specific brand of baby formula, you will feel the difference.
| Category | Skiathos | Alonissos |
|---|---|---|
| Airport | Yes (JSI), direct international flights | None |
| Beaches | 60+, mostly sandy | Fewer, mostly pebble, exceptionally clear |
| Restaurants | 100+, wide range | Limited but high quality |
| Nightlife | Full scene, bars until late | Minimal |
| Hiking | Good forest and coastal trails | Excellent, extensive marked network |
| Diving | Recreational | Peristera underwater museum, marine park |
| Accommodation | Hotels, apartments, luxury villas | Small hotels, studios, few villas |
| Crowds in August | Busy in town and headline beaches | Quiet throughout |
| Shoulder season | Services run into late October | Thins out sharply from early October |
Who Should Pick Which
Choose Alonissos if: you are travelling as a couple or a pair of friends, you dive or want to learn, you like walking for four hours without seeing anyone, you are content with the same six tavernas for a week, and you do not mind the ferry days. Late September and early October suit it particularly well — the sea is still warm and the trails are comfortable.
Choose Skiathos if: you are travelling with children or a mixed-age group, you want sandy beaches within a short drive, you value being able to change your mind about dinner at 8pm, you have a limited number of holiday days and do not want to spend two of them in transit, or you want a private villa rather than a studio.
Choose both — based on Skiathos — if: you have a week and want the marine park, the Chora and the empty coves without rearranging your logistics around a ferry timetable. This is what most of our guests do, and it is why our day trips and island hopping guide exists. For the wider picture across all four main islands, the complete Sporades guide sets out how Skopelos and Skyros fit in too.
There is a version of this trip that works brilliantly: five nights on Skiathos, one overnight on Alonissos in the middle. You get a dive or a long hike and a proper evening in the Chora, then return to a base with a kitchen, a pool and a car.
Basing Yourself on Skiathos Without the Crowds
A common objection to Skiathos is that it is busier than Alonissos. In town in August, that is true. But the island is bigger than its main street, and where you stay changes the whole experience.
Our two villas sit on the Kechria hillside on the quieter side of the island, among pine forest and olive groves, about a 15-minute drive from both the airport and the port where the Alonissos ferries leave. Each has a private infinity pool, a fully equipped kitchen, and BBQ and outdoor dining — which means you can have the Alonissos version of an evening (nobody around, dinner outside, stars) and still be twenty minutes from a fish taverna and a fast ferry. Villa Moondancer and Villa Whispering Pines both work well for the base-and-explore approach, and our location page shows exactly how the drive times work out.

Frequently Asked Questions
Is Skiathos or Alonissos better?
Neither is objectively better. Skiathos wins on access, beaches, restaurants and accommodation choice, with over 60 beaches and direct flights from nine UK airports. Alonissos wins on quiet, hiking, diving and nature, thanks to the National Marine Park. If you only have one week and want both, base on Skiathos and visit Alonissos for a day or two.
Does Alonissos have an airport?
No. Alonissos has no airport. Almost everyone arrives by flying into Skiathos airport (JSI) and taking a ferry onward, or by taking a longer ferry from Volos on the mainland. This makes Skiathos the practical gateway for an Alonissos trip whichever way you plan it.
What is the National Marine Park of Alonissos?
It is the largest marine protected area in the Mediterranean, covering roughly 2,250 square kilometres around Alonissos and the surrounding uninhabited islets. It was established primarily to protect the Mediterranean monk seal, one of the world's most endangered marine mammals, and access to the inner zones is restricted.
Can you do Alonissos as a day trip from Skiathos?
Yes. Fast ferries connect Skiathos and Alonissos in roughly an hour to an hour and a half depending on the boat and whether it calls at Skopelos. A day trip gives you Patitiri, the old hilltop village of Chora and a beach or two. Diving or serious hiking really needs an overnight stay.
Is Alonissos good for diving?
It is one of the best diving destinations in Greece. The Peristera shipwreck, a fifth-century BC cargo vessel off a neighbouring islet, opened as Greece's first underwater museum and can be visited by certified divers on guided dives. The marine park's protected waters mean noticeably healthier marine life than most Aegean sites.
Why is Alonissos being named a top island for 2027?
Travel forecasters have picked it out as an emerging destination for slow, experience-led travel, alongside places like Corfu's quieter corners. The appeal is nature, hiking, diving and a lack of mass tourism rather than nightlife or resorts — exactly the qualities that are trending as visitors move away from crowded headline islands.
Which island is better for families?
Skiathos, in most cases. It has shallow sandy beaches like Achladies and Troulos, a frequent bus route, medical facilities, and enough restaurants that fussy eaters are never a problem. Alonissos suits older children and teenagers who will enjoy hiking, snorkelling and boat trips more than a resort beach.
