Asked by first-time visitors
Greece: the questions travellers actually ask
Every question people put to an AI assistant before a first visit, answered here in full — best time to go, itinerary, entry requirements, safety, transport and where to stay, plus the details guidebooks skip.
Booking tours in Greece
Are tours in Greece worth booking in advance?
Greece — Acropolis, Santorini catamarans, Meteora monasteries and the Cyclades. The best-reviewed ones sell out first in high season, so book once your dates are fixed — most listed here confirm instantly.
Can I cancel if my plans in Greece change?
Every tour listed here offers free cancellation up to 24 hours before departure, plus reserve-now-pay-later booking, so locking in a date early costs you nothing in flexibility.
How are these Greece tours chosen?
They're sorted by review volume on Viator — the 14 operators shown are the most reviewed and best-rated for Greece, not paid placements.
What should I bring on a tour in Greece?
Comfortable shoes, sun protection, water and your booking confirmation on your phone are enough for the great majority of these excursions; boat trips add a swimsuit and towel, and check each listing for anything specific to that operator.
