New data from the photo curation app Popsa has identified the Greek islands most frequently captured in travellers' photographs, with Santorini, Mykonos and Naxos leading the rankings. By analysing anonymous location data from uploaded images, the study confirms what many holidaymakers already know: the Cyclades remain the undisputed stars of Aegean photography, thanks to their whitewashed buildings, blue-domed churches and turquoise waters.
The hashtag 'Greek islands' has amassed 4.5 million tags on Instagram alone, while individual islands such as Santorini and Mykonos each generate millions of posts. However, the popularity of these destinations has led to concerns about overcrowding, particularly in Santorini during July and August. The key to capturing that perfect shot, experts say, is timing — visiting early in the morning or late in the afternoon — and venturing beyond the main tourist hubs.
For British tourists, the Greek islands remain a staple summer destination, with direct flights from UK airports including Heathrow, Gatwick, Manchester and Birmingham. Airlines such as easyJet, Ryanair, Jet2 and British Airways operate routes to Santorini (Thira), Mykonos, Crete, Rhodes and Corfu. New for 2026, Jet2 has expanded its services from Birmingham to Kefalonia, while Ryanair added a route from Stansted to Paros earlier this year.
The Foreign, Commonwealth & Development Office (FCO) currently advises UK travellers to check the latest entry requirements, which for Greek islands means a valid passport and, for stays up to 90 days, no visa is needed for British citizens. Travel insurance is strongly recommended, covering medical expenses, cancellation and baggage loss. Costs for popular islands vary: a week in Santorini can exceed £1,500 per person for flights and accommodation in high season, while less crowded islands such as Naxos or Paros offer similar scenery for around £800–£1,000.
Beyond the top three, the Popsa list includes Crete, Rhodes, Corfu, Zakynthos, Paros, Milos and Kefalonia. These islands offer a mix of history, beaches and local culture, with Milos and Kefalonia gaining popularity for their dramatic coastlines and quieter atmosphere. Travellers seeking fewer crowds are advised to consider these alternatives, where the photographic rewards are just as high but the queues are shorter.
For those planning a trip, the practical takeaway is to book early for 2027, consider shoulder months (May, June or September) for better light and fewer tourists, and always check FCO travel advice for any local disruptions. Travel insurance should be purchased at the time of booking to cover unforeseen changes.
