Entry & Documents
Visas & Currency
Greece is a member of the European Union and the Schengen Area. Citizens of EU member states and many other countries — including the United States, Canada, Australia, and the United Kingdom — may enter Greece without a visa for stays of up to 90 days within any 180-day period. Citizens of countries not on the visa-free list should check requirements with the Greek embassy or consulate in their country of residence.
Greece uses the Euro (€). ATMs are widely available in cities, towns, and tourist areas; credit and debit cards are accepted at most hotels, restaurants, and shops, though smaller establishments and rural areas may be cash-only. It is always advisable to carry some cash, particularly when travelling to smaller islands or remote areas.
From 2025, non-EU visitors entering the Schengen Area will be required to register via the European Travel Information and Authorisation System (ETIAS) before travel. This is a straightforward online process, not a visa, but registration must be completed in advance.
When to Go
Seasons & Climate
The shoulder seasons — May to June and September to October — offer the ideal balance of warm weather, calm seas, and manageable crowds. Temperatures are comfortable for sightseeing and hiking; the sea is warm enough for swimming; and the main tourist sites and islands are busy but not overwhelmed.
July and August bring peak heat (often exceeding 35°C in Athens and the Cyclades), peak visitors, and peak prices. The meltemi wind — a strong, dry northerly that blows across the Aegean from July to September — can make sailing challenging and ferry crossings uncomfortable, but also keeps temperatures bearable on the islands.
Spring (March to May) is the finest time to visit the mainland and the Peloponnese — wildflowers carpet the hillsides, ancient sites are uncrowded, and the light is extraordinary. Autumn (October to November) is ideal for Crete, which enjoys warm temperatures well into November and is at its most authentic once the summer visitors have departed.
Health & Safety
Staying Well in Greece
Greece is a safe country with a low crime rate. Standard travel precautions apply in busy tourist areas — be aware of pickpockets in crowded markets and on public transport in Athens. The tap water in Athens and most of the mainland is safe to drink; on many islands, bottled water is recommended.
The European Health Insurance Card (EHIC) or its UK equivalent (GHIC) provides access to state healthcare for EU and UK citizens. All visitors are strongly advised to take out comprehensive travel insurance that includes medical coverage, as private healthcare costs can be significant.
Sun protection is essential, particularly in July and August. The Greek sun is intense; high-factor sunscreen, a hat, and adequate hydration are non-negotiable for anyone spending time outdoors. Pharmacies (farmakeio) are widespread and well-stocked; many pharmacists speak English and can provide advice on minor ailments.
