Skiathos is the Sporades island closest to the Greek mainland, in the northern Aegean. Small (48 km², or 19 sq mi) and very green, it is covered in pine forest running down to dozens of sandy beaches along the south coast and a few coves in the north. So what are the best things to do in Skiathos? The beach above all, but also walks to the abandoned Kastro, boat trips to the islets and Skopelos, and evenings in Skiathos Town. The island has an international airport with seasonal flights. Allow 5 to 7 days, from June to September.

Things to do in Skiathos: the highlights
Koukounaries beach
The island’s best-known beach, in the south-west: a long curve of fine sand backed by pine forest, with a protected wetland just behind it. It has sunbeds and water sports and is very busy in summer, so arrive early. The island bus links it to town along the whole south coast.
Beaches of the south and west coasts
The coast road serves a string of beaches: Vromolimnos, Kolios, Troulos, Agia Paraskevi, Platanias, then Banana and Krassa near Koukounaries. On the west side, Agia Eleni and Mandraki are quieter; Mandraki is reached by a short path through the pines. The sheltered beaches of the south are the most pleasant when the north wind blows.
Lalaria and the northern caves, by boat
On the wilder north coast, Lalaria beach is enclosed by cliffs and covered in white pebbles; it is reached mainly by boat. Round-the-island trips from the old harbour follow the sea caves of the north coast (Skotini, Galazia), stop at Lalaria and pass below the Kastro.
The Kastro, the old capital
In the 14th century, the islanders left the coast, too exposed to pirates, and settled on this naturally fortified headland in the north of the island. Ruins and a few churches remain above the sea. Get there by road and then on foot, or by boat.
Evangelistria monastery
In the hills a few kilometres from town, this monastery holds a special place in Greek history: the island claims that the first flag of modern Greece was raised here in 1807. The site is surrounded by pine forest and makes a good short hike.
Skiathos Town, the Bourtzi and the Papadiamantis house
The town, built from the 1830s onwards, is laid out around two harbours separated by the Bourtzi peninsula, where remains of an old fortress and a cultural centre stand. In the lanes, the birthplace of the writer Alexandros Papadiamantis, who was born and died on Skiathos, is now a museum. In the evening, Papadiamanti Street and the old harbour are lined with restaurants and bars.
Skopelos and Alonissos as day trips
Ferries and excursions link Skiathos with Skopelos, larger and more mountainous, and then Alonissos, home to a national marine park. One day is enough to see Skopelos harbour; Alonissos is better with an overnight stay.

When to go to Skiathos
The season runs from May to October. June and September are the best compromise: pleasant sea, long days and fewer people than in July and August, when the island and its beaches are at their busiest. May and October are cooler but suit walking. In winter, most hotels and restaurants close and connections become scarce.
We found no official climate normals published for Skiathos (the Greek meteorological service does not publish any for the island), so we do not publish a table of average temperatures. As an indication, the Skiathos station of the meteo.gr network (National Observatory of Athens) recorded in 2025 an average maximum of 33.0 °C (91 °F) in July and only 6.2 mm (0.2 in) of rain from June to August; these are figures for a single year, not a climate average.

Our calculation: in mid-June, 2 h 53 of daylight remain after 6 pm, compared with 0 h 47 in mid-October. For a late-afternoon beach session, June and July have the longest evenings. For other regions, see the best time to visit Greece.
Budget for Skiathos
Prices rise sharply in July and August. Studios cost less than beachfront hotels; the south coast bus is the cheapest way to get around, while car or scooter hire and a round-the-island boat trip add to the budget.
Getting around Skiathos
- Bus: one line runs along the south coast from town to Koukounaries, with numbered stops in front of each beach; frequent in summer.
- Car, quad or scooter: handy for the west, the north and Evangelistria; roads are narrow and winding.
- Boats: shuttles and excursions from the old harbour to the beaches, the north of the island and the islets.
- Getting there: by air (the airport, with a short 1,628 m (5,341 ft) runway, is known for its low approaches over the sea) or by ferry from Volos, Agios Konstantinos or Thessaloniki.
Where to stay in Skiathos

Entry requirements, health and safety
- US citizens: Greece is in the Schengen area: you may enter without a visa for up to 90 days for tourism or business. Greek law requires three months of passport validity beyond your departure date, but the State Department recommends at least six months; you may be asked for proof of sufficient funds and a return ticket (U.S. Department of State, travel.state.gov, last updated February 19, 2026).
- UK citizens: no visa for up to 90 days in any 180-day period as a tourist. Your passport must have been issued less than 10 years before the day you arrive and be valid at least 3 months after the day you plan to leave the Schengen area. Under the EU Entry/Exit System, the Greek authorities have indicated that they will not collect fingerprints and photos from UK travellers: follow the advice of officials on the ground (UK FCDO, GOV.UK, updated 11 August 2026).
- Health: UK travellers can use a GHIC or EHIC for state healthcare (GOV.UK); whatever your nationality, take out travel insurance covering medical costs. There is a health centre in town.
- Wildfires: according to the UK FCDO (GOV.UK, updated 11 August 2026), the wildfire risk is high from April to October; make sure your phone can receive emergency alerts. Causing a wildfire is a criminal offence in Greece, even if unintentional. Skiathos is heavily wooded. If you see a fire, call 112.
- Swimming: many organised beaches use a flag system, and a red flag means you must not enter the water; take extra care where there are no lifeguards, flags or signs (GOV.UK).
- Earthquakes: tremors and earthquakes occur regularly in Greece (U.S. Department of State, travel.state.gov).

Practical tips for Skiathos

- Fire: never throw a cigarette end in the pine forest; GOV.UK advises not lighting fires, as it is both dangerous and illegal given the wildfire risk.
- Ferries: book ahead in summer, especially for Skopelos and Alonissos at weekends.
- Mobile data: check your home carrier’s roaming charges before you go.
