It’s a crammed, jammed vacation destination.
While the official motto of Malta isn’t “the more the merrier,” it seems the itty-bitty, buzzy hotspot, smack-dab in the central Mediterranean Sea, is steadily welcoming visitors from all corners of the Earth, making it Europe’s most overcrowded island for 2026, per a trending new study.
But its eye-popping popularity may cause the country’s collapse, experts warn.
“Europe’s islands are experiencing tourism on an unprecedented scale,” said Sean Kelly, co-founder of BookRetreats, a global marketplace for wellness getaways, in the report.
Researchers analyzed tourism density across “true islands” in Europe using the most recent available data from the European Commission (2023).
And although Mallorca, an expansive island in Spain, draws the highest number of tourists overall, “no island concentrates tourism quite like Malta,” the insiders say of the world’s 10th smallest country, which spans just 316 km² (122 square miles).
That’s tiny enough to fit inside New York City and London nearly three and five times, respectively.
“The data highlights just how concentrated the pressure is, with Malta topping the list, cramming over 38,000 overnight stays per km², and three of the five most overloaded islands in the Canaries,” Kelly continued. “These places weren’t built for millions of visitors a year, and the protests we’re seeing across Europe are a clear sign that the way we travel needs to shift.”
Viral visuals of Malta’s overcrowded streets, swarmed with sweaty sightseers congesting walkways, have garnered roughly 50,000 views on the Instagram account “Overtouristed Malta.” The profile is dedicated to decreasing the number of the nation’s visitors — namely British travelers, according to the study.
“Malta is too small for over 4 million tourists a year. It simply can’t handle it,” reads a caption beneath footage of folks herding through its capital city, Valletta.
The post goes on to paint a horrifying picture of the “hell” locals are forced to endure, especially during the stifling summer months, while guests with “zero spatial awareness” clog their communities.
“The impact is most visible at peak sites like the Blue Lagoon on Comino, where daily summer crowds reach up to 12,000,” the study revealed. “In response, authorities have recently capped visitor numbers at 4,000 per day and introduced mandatory booking to help protect the fragile coastal environment.”
The concerns and complaints notwithstanding, Malta’s government is aiming to grow annual arrivals to 4.5 million by 2034, putting the oasis at risk of ruin.
“The question is no longer whether Malta can attract tourists, but whether it can do so without losing what makes this island so special,” wrote the authors.
Malta, unfortunately, isn’t in a class by itself as it pertains to Europe’s most overpopulated paradises.
Lanzarote, the easternmost of Spain’s Canary Islands, has secured the second place position on the overcrowded roundup this year.
Boasting golden beaches, volcanic landscapes and mild climate, the haute haven receives over 21,600 overnight stays per km², making it Spain’s most jam-packed island. And while tourist dollars keep its economy thriving, natives claim their land is barely surviving.
“Tourism accounts for around 35% of the Canary Islands’ GDP. Yet many locals argue that the social and environmental costs are beginning to outweigh the benefits,” the report explained. “Residents are calling for limits on visitor numbers, stricter controls on short-term rentals and stronger protections for Canarian culture and daily life.”
Ibiza and Formentera earned the No. 3 spot on the problematic list.
Despite shining as symbols of Balearic tourism, thanks to their otherworldly beaches, nightlife and summertime shindigs, the islands are now struggling under the weight of their popularity.
After welcoming a staggering 3.7 million trippers in 2024, residents have experienced surges in rent, gridlocked local roads and insufficient support for its beaches and basic services.
“Rising costs and a shrinking supply of housing have pushed the islands to a tipping point,” per the findings.
To mitigate the mayhem, officials responded with new Tourism Containment Measures in April. The reforms ban new short-term rentals in apartment buildings, and bar unlicensed holiday rentals.
