There is something quietly devastating about watching a dream destination slowly collapse under the weight of its own fame. Islands, by their very nature, promise escape. Turquoise water, unhurried mornings, local culture that feels genuinely alive. Yet some of the world’s most iconic island destinations are now battling a crisis that no postcard will ever show you.
In 2024, with travel rebounding globally, overtourism hit harder than ever. Famous destinations like Venice, Bali, and Barcelona were already grappling with overcrowding, and the effects were noticeable: from environmental damage to overwhelmed local services and the displacement of residents. The numbers are staggering. The protests are real. The charm, for many of these places, is fading fast. Let’s dive in.
1. Santorini, Greece: The Instagram Paradise Cracking Under Pressure
Let’s be real – Santorini is one of the most photographed places on Earth. Those blue domes, those sunsets over Oia. You have seen the images a thousand times. But here is what the algorithm does not show you: Santorini’s charm is in its quiet, picturesque villages and crystal-clear waters, but the flood of tourists – many arriving on large cruise ships – has led to severe overcrowding. In peak season, visitors often outnumber the island’s 15,000 residents several times over.
In 2024, reports emerged of up to 18,000 cruise passengers overwhelming the island in a single day, straining resources for its 15,000 permanent residents. Think about that for a moment. More tourists arriving on one afternoon than there are people who actually live there. Garbage collection in Santorini’s village of Oia spikes from 2 tons per day in February to over 26 tons per day in August, despite no significant rise in permanent population.
Santorini’s infrastructure struggles under the weight of so many visitors. There are serious concerns about the island’s water supply, as well as the impact of constant construction to accommodate tourists. Municipalities have implemented caps, limiting cruise ship disembarkation to 8,000 passengers per day – a response that came far too late for many locals who feel their home has already become unrecognizable.
2. Mykonos, Greece: From Bohemian Retreat to Overrun Party Island
Mykonos once had a reputation as a sun-soaked hideaway with genuine soul. Artists, philosophers, and wanderers used to gather there. Today, the story reads very differently. Mykonos now welcomes upwards of 2 million visitors each year, and according to some projections, the island might see as many as 3 million in 2025.
The result, critics say, is sky-high prices – including at beaches that require a fee to access – uncontrolled partying, and subpar dining options. Not to mention an influx of influencers crowding many of the island’s most photogenic spots, such as the beautiful windmills of Kato Mili and blue-domed churches. Honestly, when a destination is better known for photo ops than for authentic experience, something has been lost.
Greek officials are aware of the problem. In 2024, the government was considering a cap on the number of cruise ships that could sail around Greece’s Cycladic islands, and in 2025, new per-passenger port fees went into effect. In Greece, residents in Athens and Paros have protested against overtourism, accusing tourists of displacing locals and diluting the cultural character on islands like Santorini and Mykonos.
3. Bali, Indonesia: A Tropical Paradise at a Breaking Point
Bali is many things to many people. For some, it is a spiritual sanctuary. For others, a digital nomad hub. For locals, increasingly, it is a source of deep anxiety. In 2024, Bali welcomed 6.33 million international visitors, slightly surpassing the previous peak of 6.28 million in 2019. On top of that, in 2024 there were 22.64 million domestic trips to Bali, a huge jump of more than a quarter from 2019 levels.
From the moment you arrive in Denpasar, the issues are obvious: lengthy traffic delays plague the route between the airport and Ubud, beaches are marred by plastic and endless rows of sunbeds, rice terraces suffer under the feet of Instagram seekers, and at revered temples, selfie sticks seem to outnumber actual offerings. Religious ceremonies, once reserved for the community, are now transformed into shows for tourists. Some temples are visited without any respect for Balinese cultural codes. Mass tourism has emptied the spirituality from many places, reducing them to backdrops for selfies and social media content.
The region has faced overtourism leading to a strain on natural resources, with water scarcity emerging as a particularly pressing issue. A 150,000 rupiah tourist levy introduced in February 2024 was intended to fund conservation and cultural projects. However, Bali’s tourism office acknowledged that only roughly 35 percent of international visitors actually paid it in 2024. A tax that barely gets collected is a policy that barely exists.
4. Mallorca, Spain: An Island Where Locals Are Living in Their Cars
Mallorca has long been the sun-and-sea playground of Europe. And for a very long time, that arrangement worked just fine. The Balearic Islands, with Mallorca as its largest island, have been experiencing a surge in tourism in recent years. According to data from The Mirror, the Balearic Islands saw an astonishing 18.7 million visitors in 2024, and this number exceeded 19 million in 2025.
Short-term rentals surged, producing housing scarcity. Reports in 2024 note around 1,000 people in Mallorca living in vehicles because they simply cannot afford rent in their own hometown anymore. That is not a footnote in a policy document. That is a human catastrophe unfolding in a place people fly to for leisure. In July 2024, 20,000 people demonstrated against mass tourism in Palma de Mallorca.
In an effort to tackle overtourism and preserve the charm of Palma and the Balearic Islands, Mallorca is set to introduce new cruise ship regulations starting between 2027 and 2029. The island will reduce the number of cruise ship passengers during peak summer months, aiming to alleviate the strain on local infrastructure and historic sites. Ibiza and Mallorca have also begun enforcing fines of up to €3,000 for antisocial behavior and unlicensed rentals. Meaningful reforms – but whether they come early enough remains the real question.
5. The Canary Islands, Spain: Tourism GDP at 36 Percent, Residents Still Going Hungry
Here is a contradiction that should give anyone pause. Tourism employs four in ten islanders in the Canary Islands and accounts for 36 percent of GDP. You might expect that kind of economic dependence to translate into prosperity for locals. Instead, in the Canary Islands in 2023, a third of residents were at risk of poverty. That is one of the most unsettling statistics in modern tourism.
In April 2024, mass protests began in the Canary Islands, with residents calling for a temporary limit on tourism until legislation to combat the negative effects of overtourism could be introduced. Between 20,000 and 50,000 people across the islands took part in coordinated protests against the excess tourism. The protests were backed by environmental organisations including Greenpeace and the WWF. The Canary Islands, which in 2023 played host to over seven times their resident population of 2.2 million, are dealing with some pretty serious consequences as a result of overtourism.
The Canary Islands grew from roughly 9 million annual visitors in the early 2000s to more than 16.2 million in 2023, with tourism representing nearly one-third of GDP. The archipelago now imports almost 80 percent of its food because agriculture has been squeezed out by tourism monoculture. On Tenerife, authorities have announced that a new eco-tax will be introduced to protect a popular national park – a small measure for a very large problem.
6. Ibiza, Spain: When the Party Ate the Paradise
Ibiza was not always a byword for excess. Before the megaclubs and the bottle service and the influencer yachts, it was a whitewashed, tranquil island with something quietly magical about it. That version of Ibiza is increasingly hard to find. Ibiza is famous for its party scene, Mediterranean beaches, and nightlife, yet overtourism affects locals and visitors alike. Nightclubs dominate entertainment, while quieter villages lose traditional character. Popular beaches are overcrowded, with environmental concerns like litter and coastal degradation.
Accommodation costs surge during peak season, and streets can feel overly commercialized. Despite its allure, travelers note that the island’s original charm and slower pace are fading. By 2024, an unspecified number of Ibiza residents lived in their vehicles – a situation strikingly similar to Mallorca and a clear sign that the housing crisis is an archipelago-wide emergency, not a one-island fluke.
Youth unemployment hovers near 27 percent on Ibiza, which is a staggering figure for an island whose economy is supposedly thriving on tourism. In June 2025, large demonstrations were reported across Spain, where thousands of residents marched chanting slogans such as “Your holidays, my misery,” with similar demonstrations occurring in Ibiza, where residents voiced concerns that excessive tourism was driving up the cost of housing and straining public services. The party, it seems, is happening for everyone except the people who actually live there.
The Social Media Effect: How Instagram Is Accelerating the Damage
Cheap flights, social media exposure, and the lure of bucket-list experiences drive tourists to the same small set of locations, all at once. The result is a feedback loop that is very difficult to break. An island goes viral. Visitor numbers spike within months. Infrastructure buckles. The authentic experience that made the place viral in the first place begins to disappear.
Instagram has had a huge influence on overtourism in Bali. Places like Lempuyang Temple or Tegenungan Waterfall have become viral spots, causing daily overcrowding and distorting the spiritual experience entirely. The same pattern plays out on every island in this list. Influencers, both established and aspiring, crowd the most photogenic spots, such as the beautiful windmills of Kato Mili in Mykonos.
A 2023 study by the World Travel and Tourism Council found that 77 percent of all tourist overnight stays in island destinations occur on just 5 percent of their land area. This figure underscores a crucial spatial paradox: while entire archipelagos are promoted globally, tourism is physically concentrated in extremely narrow zones. Social media does not show you an island. It shows you three streets, two beaches, and one photogenic temple. Everyone floods those exact same spots.
The Housing Crisis Nobody Warned You About
Tourist destinations can quickly fall victim to their own popularity. As more construction and businesses are created to meet the needs of tourists, these places risk losing the very character and identity that made them so popular. Nowhere is this more painfully visible than in the housing markets of these islands. Locals are being priced out, displaced, sometimes literally forced to live in their cars.
Short-term rentals now dominate the housing market on many islands, thanks to affordable flights and the digital nomad craze. This has led to skyrocketing rents and displaced locals. In places like Cinque Terre, overtourism pushes up housing prices, forcing locals to leave because they cannot afford to live there anymore. Local shops and services often start focusing on tourists instead of residents – stores now sell souvenirs rather than groceries.
Think of it like this: imagine waking up one day to find your neighborhood’s grocery store has been replaced by a souvenir shop selling snow globes of your own home. That is exactly what is happening to communities on these islands. A 2024 survey on the impact of overtourism on travel plans in Europe found that over a quarter of respondents intended to avoid visiting overcrowded destinations in the year ahead. Even travelers are beginning to notice something is wrong.
What Governments Are Actually Doing About It
Many popular destinations are implementing measures to mitigate the effects of overtourism, such as visitor caps, entry fees, or timed tickets. The efforts are real, but the question of whether they are decisive enough is still very much open. Greece, for example, introduced new per-passenger cruise fees. Bali introduced a tourist tax, though compliance has been spotty at best.
Since January 2025, the town of Mogán on Gran Canaria has implemented a fee of €0.15 per person per day for all visitors staying in the region, aiming to generate additional funding for local projects including beach maintenance, waste management, and sustainable infrastructure development. In Barcelona, Mayor Jaume Collboni said that he would end short-term rentals in Barcelona by 2028, aiming to reduce the impact on the housing market of landlords renting properties at inflated rates intended for tourists.
The common thread across nearly every government response is that the measures feel reactive rather than preventive. Mallorca’s decision to reduce the number of cruise ship passengers visiting between 2027 and 2029 marks a significant shift in the island’s approach to tourism. As overtourism continues to be a pressing issue for many popular destinations, Mallorca is taking steps to protect its cultural heritage, environment, and residents’ quality of life. Whether those steps come in time remains to be seen.
The Visitors Are Starting to Notice Too
Once-idyllic places have turned into overrun tourist traps, losing their unique charm and becoming unpleasant to visit. That is not just the perspective of exhausted locals. Increasingly, it is what tourists themselves report. The five-star review that promises paradise and delivers a traffic jam. The beach that looked cerulean in the photo and shows up littered with sunbeds in real life.
Historically, destinations that fail to manage mass tourism effectively follow a downward trend: increased tourism means decreased satisfaction, which leads to fewer repeat visits and less positive word-of-mouth, reduced willingness to spend, and a race to the lowest prices, attracting even more budget-conscious tourists to compensate. Hotels in areas like Canggu and Ubud in Bali are already reporting that average daily rates in shoulder seasons are approximately 10 to 15 percent lower than 2023 levels in real terms, despite rising costs of land and operations.
The two locations that have arguably had the most vocal protest movements, Barcelona and Mallorca, show the biggest declines in demand compared to 2024. It is a kind of ironic justice. When a destination is destroyed by its own popularity, that popularity eventually begins to erode. Some European and Australian tour companies are already seeing booking declines for 2025 to 2026 relative to the post-pandemic highs of 2024, with travelers inquiring about quieter, cleaner alternatives such as Lombok, Sumba, or Sri Lanka.
A Future Worth Saving
None of this means these islands are beyond hope. They are still beautiful. They still hold cultural depth and natural wonder that is genuinely worth experiencing. The point is not to stop traveling. The point, honestly, is to travel with eyes open.
The list of the most beautiful destinations affected by overtourism is long. This is not to suggest people should not travel to these places, but it is worth being mindful of the impact you are having on the places you visit. Water consumption is up to 400 percent higher per capita in tourism zones compared to rural villages just 15 kilometers inland. Every cold shower skipped, every plastic bottle tossed, every hotel room left empty with the air conditioning on full blast is a real cost extracted from a real community.
The islands in this article are not cautionary tales about travel itself. They are cautionary tales about what happens when destinations become products rather than places. When the people who live there become inconveniences rather than the very reason the culture worth visiting exists in the first place. If we want these islands to keep their charm, the first step is admitting that the way most of us have been visiting them is part of the problem. What would you be willing to change on your next trip?
