Santorini Mykonos Tourism Drop Shocks Greece in 2025

For years, Santorini and Mykonos stood as Greece’s crown jewels dream destinations known for their whitewashed houses, blue-domed churches, and breathtaking sunsets. But in 2025, both islands will witness a noticeable decline in visitors. Once overflowing with tourists from around the world, these Aegean hotspots are now seeing emptier streets, lower ferry bookings, and quieter hotels.

While Mykonos still manages to draw steady crowds, Santorini’s downturn has been sharper, raising questions about what’s driving this unexpected shift in Greece’s tourism landscape.

A Decline in Numbers

According to tourism data, Santorini recorded an 18% fall in air traffic during the first seven months of 2025, with both domestic and international arrivals down significantly. Ferry bookings reportedly dropped by almost 50% early in the year. Mykonos, meanwhile, faced a smaller decline around 3% to 4% but still notable for an island that thrives on luxury tourism.

July’s shipping data paints a clearer picture: passenger traffic fell nearly 20% in Santorini and 15% in Mykonos compared to the previous year. Even though these islands are still among the top destinations in Europe, it’s clear that visitor enthusiasm has cooled.

What’s Behind the Decline?

Several factors have combined to create this downturn. Perhaps the most immediate cause was seismic activity earlier in the year around Santorini. Although there was no major damage, headlines about potential quakes led some travelers to cancel or change their plans.

But the drop isn’t only about safety concerns. The islands have also struggled with the effects of overtourism, rising costs, and changing traveler preferences.

Over the past decade, Santorini and Mykonos became victims of their own popularity. Prices for accommodation and dining skyrocketed, and the once-charming narrow alleys became overcrowded. Many visitors started describing the experience as “beautiful but exhausting.”

As a result, tourists especially from Europe and North America began exploring lesser-known Greek islands like Naxos, Paros, and Milos. These destinations offer the same Aegean charm but with fewer crowds, lower prices, and a more authentic atmosphere.

The Impact of Overtourism

For years, both islands relied on cruise ships and short-stay visitors who brought in high daily numbers but not always high spending. Local communities began voicing concerns about overcrowding, waste management, and the strain on local infrastructure.

In response, Greek authorities introduced new taxes and fees for cruise visitors in 2025, aiming to control tourist volume and protect the fragile environment. While this move was welcomed by environmental groups, it also contributed to fewer arrivals in the short term.

Many travel experts say this adjustment was inevitable. “Santorini and Mykonos reached a saturation point,” says one tourism analyst. “What we’re seeing now isn’t a collapse, it’s a correction. The islands are shifting from quantity to quality.”

Shifting Traveler Behavior

Post-pandemic travel habits have changed dramatically. Today’s tourists are seeking authentic, quieter, and more sustainable experiences. Instead of crowded luxury spots, they want local culture, traditional food, and outdoor activities away from mass tourism.

This global trend has affected destinations that rely heavily on their brand image rather than diversity of experiences. Santorini and Mykonos, while iconic, are now facing competition from emerging destinations that promise more genuine interactions.

Travel agencies in Athens have noticed a rise in demand for smaller islands in the Cyclades, places where visitors can enjoy Greece’s beauty without paying Mykonos prices or battling Santorini crowds.

Economic Ripple Effects

The tourism slowdown has had a noticeable effect on local economies. Businesses that thrived during peak seasons hotels, restaurants, and tour operators are now offering discounts up to 40% just to maintain occupancy.

In Mykonos, the luxury segment remains strong thanks to loyal high-end travelers, but mid-range hotels are struggling. Santorini, with its heavier reliance on mass tourism and cruise visitors, has felt a more painful impact.

Local workers have also been hit. Many seasonal employees depend entirely on tourism income, and fewer arrivals mean shorter contracts or reduced working hours. The Greek government has announced support measures for affected workers, especially in Santorini, to help them manage through the slump.

Safety Concerns and Perception

Even though seismic activity around Santorini has been minor, perception plays a powerful role in tourism. Media coverage of possible earthquakes earlier this year made some travelers nervous. Although experts assure that the island remains safe, uncertainty lingers.

Tourism professionals say rebuilding confidence will take time. They’re urging airlines, travel agencies, and the Greek National Tourism Organization to promote the islands with updated messaging focusing on safety, sustainability, and off-season charm.

A Chance for Reinvention

Despite the current downturn, many locals see this moment as an opportunity. For years, both Santorini and Mykonos have battled with overtourism and now, with fewer crowds, they have a chance to rethink their future.

Local councils and tourism boards are discussing ways to shift from mass tourism toward quality-based tourism focusing on longer stays, cultural activities, and eco-friendly travel options.

Some hotels are investing in sustainable design and promoting experiences like vineyard tours, hiking, and local art workshops instead of just beach clubs and nightlife. If done right, this transition could lead to a more balanced, resilient tourism model for the islands.

Mykonos: Holding Steady

Mykonos has weathered the situation better than Santorini, thanks in part to its diversified tourism base. While it remains a luxury hotspot, it has also become a favored destination for domestic travelers.

Greek residents, who once avoided the island due to high prices, are returning thanks to off-season promotions and new flight deals. Local businesses have responded by extending their operating seasons beyond summer and introducing more family-friendly packages.

Although the numbers are down compared to 2024, the island’s reputation for style, nightlife, and premium service continues to draw loyal visitors from around the world.

Santorini: Searching for Balance

Santorini, on the other hand, faces a tougher path to recovery. The island’s economy is heavily tied to mass tourism and cruise traffic. With ferry and flight numbers declining, local businesses are feeling the pressure.

However, there’s also a renewed focus on cultural tourism. Museums, traditional villages like Pyrgos and Megalochori, and wineries are being promoted as alternatives to the over-visited caldera area. This shift could help spread visitors more evenly and preserve Santorini’s beauty for future generations.

The Road Ahead

Tourism experts believe that by late 2026, both islands could regain stability if they continue to adapt. Sustainability, safety assurance, and smarter management will be key.

While the Santorini Mykonos tourism drop has caused short-term challenges, it’s also forcing much-needed change. The islands are being pushed to move beyond mass tourism and focus on offering real value.

As one hotel owner put it, “We had too much of a good thing. Maybe now we can find a better balance of fewer people, but more meaningful experiences.”

Conclusion

The recent downturn in visitors to Santorini and Mykonos isn’t just a setback, it’s a turning point. It reflects broader global shifts in travel behavior, economic pressures, and sustainability awareness.

While numbers are down now, the long-term future could be brighter if the islands evolve wisely. Tourists may one day return in greater numbers, not just for the view but for the experience.

For travelers, this moment presents an opportunity too: visiting Greece’s most famous islands without the usual crowds might just be the best way to rediscover their timeless magic.
