Greece, Summer
A curated packing list for your trip between Athens, the Cyclades, and the slow ferries that connect them. Built for blistering July sun, dry island wind, and the particular pace of summer in Greece.
Border & arrival
What customs and immigration expect.
On the ground
How life actually works once you arrive.
Schengen visa-free, ETIAS launches Q4 2026
US, UK, Canadian, Australian, and most non-EU citizens enter visa-free for up to 90 days within any 180-day period. ETIAS travel authorization (€20, valid 3 years) launches in Q4 2026 for visa-exempt nationals. Passport must be valid 3+ months beyond your departure date.
Athens runs hotter than the islands
Athens hits 35-40°C in July-August thanks to the urban heat island. Cyclades islands stay 5-8°C cooler with the meltemi wind. Plan Athens for early morning or evening; plan the islands for the harsh midday hours.
Acropolis is timed entry, capped at 20,000/day
Tickets are sold in 2-hour entry slots (€30 regular, €15 reduced) via the Hellenic Heritage e-ticketing system. The 20,000 daily visitor cap means peak slots sell out, book 2-3 weeks ahead, and aim for the 8am opening to beat heat and crowds.
Ferries sell out 2-3 months ahead
Santorini-Mykonos is the busiest tourist route in Greece (€82-90, 2-3.5 hours). For July and August departures, book 8-12 weeks out via Ferryhopper or directly with carriers (Seajets, Blue Star, Fast Ferries).
Cards everywhere, cash for tips
Cards are accepted nearly universally by law (mainland and islands). Cash is preferred for tipping, 5-10% at restaurants, small notes for taxis, hotel staff, and tour guides. Skip the airport currency exchange; ATMs work fine.
Type C/F plugs at 230V
European-standard outlets (same as France, Germany, Italy). 50Hz frequency. US/Canadian devices need an adapter; check voltage on hair tools and curling irons (most are not dual-voltage).

Clothing
Light, breathable, sun-protective. Modest layer for monasteries and Mt. Athos. One nicer outfit for Santorini sunset dinners.
Shoes
Acropolis marble is slippery; Cycladic streets are cobblestone. Sandals plus real walking shoes.
Toiletries & Personal Care
Sunscreen is the priority. Pharmacies are excellent if you forget anything.
Health & Medications
Heat-related issues are the main risk. Hydration salts and a small kit go a long way.
Documents & Money
Cards work everywhere; cash for tipping and small island shops.
Tech & Electronics
Type C and F plugs at 230V. EU travelers can skip the adapter; US/CAN/UK travelers need one.
Luggage & Organization
Soft-sided bags travel ferries better than wheels. Cycladic alleys defeat suitcase wheels anyway.
Comfort & In-Transit
Ferries can run 5+ hours; keep yourself fed and entertained.
Weather & Climate Gear
This is what saves your trip. Greek summer punishes the under-prepared.
Cultural & Activity-Specific
Modesty for churches and monasteries; beach culture is relaxed otherwise.
Safety & Precautions
Greece is generally very safe; pickpockets work tourist-heavy zones in central Athens.
