Rules in force · 10Non-EU visitors get 90 days in any rolling 180-day window…Mine-suspected land still exists in Bosnia and Herzegovin…
- Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
- Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
- Balkans ↗Mine-suspected land still exists in Bosnia and Herzegovina and in pockets of Croatia's former front line: outside towns keep to tarmac and waymarked paths, and treat red triangle signs and taped-off fields as absolute.
- Balkans ↗Serbia refuses onward entry to travellers who reached Kosovo from a third country and then try to cross straight into Serbia; route Kosovo–Serbia legs through North Macedonia or Montenegro, or start the loop in Serbia.
- Balkans ↗Hire cars need written permission from the rental company and valid insurance for every country on the line; Kosovo sells its own border insurance and some contracts exclude Albania, Kosovo or Bosnia outright.
- Greece ↗Greece is in the EU and the Schengen area: check entry rules, the EU Entry/Exit System and any travel authorisation requirement for your passport on official sources.
- Greece ↗Taking stones, pottery or other objects from archaeological sites is illegal; so is exporting antiquities without a permit.
- Greece ↗Do not photograph military sites or border zones; signs mark them.
- Greece ↗Acropolis tickets are sold for one-hour entry slots on the official Hellenic Heritage site (hhticket.gr); in peak season slots sell out days ahead, and you cannot enter outside your hour.
- Greece ↗Businesses must give a receipt (apodeixi) for every sale; ask for one, and do not accept a handwritten note in place of it.
Hydra is a car-free island 1.5–3 h by sea from Piraeus, with a horseshoe harbour, stone mansions and no motor vehicles beyond a few municipal trucks. Day trippers fill the waterfront from about 11:00 to 18:00; after the last boats leave, the port and the lanes behind it go quiet. Two nights is enough for the town, a swim and a walk.

Arrive & move
Airports are listed under At a glance; this is how to move once you are in
Getting around
On foot only: no cars, scooters or motorbikes for visitors. The town is walkable in minutes; Kamini is a 15–20 min coastal walk. Boat taxis and donkeys wait at the port for longer hops, with posted fares. Bring shoes with grip — the lanes are stepped and polished smooth.
See & do
Day-trips, door to door
Day-trips
Door to door: About 30–45 min
Ferry or hydrofoil from Hydra port
The natural pairing; many Hydra boats continue there.
Door to door: About 1–1.5 h
Ferry via the Saronic route
Pine-covered town across the strait from the Peloponnese.
Aegina
cautionDoor to door: About 1.5–2 h
Ferry toward Piraeus
Better as a stop on the way back to Athens than a return trip.
Door to door: 2.5–4 h
Ferry or hydrofoil to Piraeus, then metro or taxi
Plan the ferry first: the last convenient boat leaves mid-afternoon.
Eat & sleep
Which area to sleep in
Where to sleep
Areas, not hotels: pick the one that fits your arrival time and plans.
Harbour and waterfront lanes
Everything within a 5-min walk: ferries, tavernas, shops. Noisiest at night in season.
Back lanes of Hydra town
2–8 min uphill from the port; quieter, but most places mean stairs with your bags.
Kamini
About 1 km west along the coast road, 15–20 min on foot; fewer rooms, cheaper tavernas, Spilia swimming below.About 0.6 mi west along the coast road, 15–20 min on foot; fewer rooms, cheaper tavernas, Spilia swimming below.

- Sea urchins on the rocks at Spilia and Vlihos: wear something on your feet.
- Donkey traffic on the lanes: watch your step.
- Most seafood on menus is frozen and imported; local fish is priced accordingly.
