Greek tours fall into 8 main categories: sailing and catamaran (the most popular by booking volume), wine and food, sunset experiences, hiking, cultural and archaeological, volcano and hot springs, photography tours, and private driver days. Every operator listed has been used personally by our editors or by trusted local partners in the last 12 months.
Bookings split roughly 60/40 between Viator (broader inventory, better last-minute availability) and Get Your Guide (smaller-group experiences, sharper curation). Prices are identical across the two for the same tour. We earn a small affiliate commission either way; it keeps the guides free and does not change what we recommend.
For Santorini specifically, the sunset catamaran is the single most-booked tour on the island — book it for your first or second night rather than the last, so weather can force a reschedule without ruining the trip.
