Cancún was once considered the crown jewel of the Caribbean, a purpose-built paradise that somehow managed to feel both glamorous and accessible. For decades, it delivered exactly what it promised: turquoise water, white sand, and affordable luxury just a short flight from the U.S. Today, though, the cracks are showing. A growing number of travelers are pausing before hitting “book” on that Cancún resort, with rising prices, persistent safety concerns, cartel-fueled instability, severe overtourism, and a destination identity crisis all reshaping how tourists think about the city. Here are six documented reasons why Cancún simply .
1. Visitor Numbers Are Actually Declining
Cancún International Airport became the busiest in Mexico, with over 20 million tourists touching down in 2024. That sounds like a success story on the surface. But dig deeper and the trend is moving in the wrong direction. In the first half of 2025, Cancún saw a decrease of 6.5% in arrivals, dropping to approximately 2.89 million from just over 3 million in 2024, while other popular locations followed a similar trend.
Latin America’s top tourist destination suffered a surprising slump during a key holiday season, with international passengers at the Cancún airport dropping almost 14% in July and August 2024 compared to the previous year, deepening a decline that had started in April. The summer of 2024 also brought its own embarrassments. According to a report by STARC, the city recorded a 13.6% drop in international traffic during August, and Cancún was not the only tourist hotspot to record a decline. Americans, by far the largest group of foreign travelers to Mexico’s Caribbean beaches, overwhelmingly picked Europe as their preferred leisure spot.
2. Safety Concerns Are No Longer Just Background Noise
In February 2024, the most common crimes in Cancún were robberies, accounting for nearly 27% of all documented crimes, followed by domestic violence and property damage. These numbers reflect a city where crime has become routine rather than exceptional. The homicide rate in Cancún in 2024 was approximately 64 per 100,000 residents, based on INEGI’s official crime statistics.
As of 2024, roughly 77% of Cancún residents believe the city is not safe, and more than a third feel their own neighborhoods are unsafe. The U.S. government has taken note as well. The U.S. Department of State issued a Level 2 advisory for the state of Quintana Roo, encouraging travelers to “exercise increased caution” due to rising crime rates, particularly petty thefts and occasional violent incidents. In February 2026, cartel violence triggered by the killing of El Mencho spread to Quintana Roo, prompting the U.S. Embassy to issue a brief shelter-in-place directive that included Cancún, Playa del Carmen, Cozumel, and Tulum.
3. Prices Have Climbed Beyond What the Destination Can Justify
Cancún built its reputation on delivering a luxury tropical experience at a price point that was more approachable than the Caribbean islands. That value proposition has eroded significantly. Mexico’s inflation rate reached 4.72% in 2024, and inflation in food and energy rose into double digits in the latter part of that year, with the minimum wage raised by 12% on January 1, 2025, forcing businesses to pass those extra costs on to customers.
Fluctuations in currency exchange rates and a strengthening U.S. dollar have made Cancún more expensive for travelers from countries with weaker currencies, and even Americans were feeling the pinch as resort prices climbed well beyond what seemed reasonable for a Mexican vacation. The scam culture hasn’t helped either. Everything from restaurants adding tips into the bill, beach clubs overcharging, or stores offering fake tax-free shopping reflect a tourism environment where dishonest practices have become normalized. Scams in Cancún include fake “helpful” strangers at ATMs, overly aggressive tour sales, taxi drivers taking longer routes or overcharging, and timeshare pressure tactics dressed up as “free offers.”
4. The Sargassum Crisis Has Become a Seasonal Disaster
Ask anyone who visited Cancún during peak sargassum season and you’ll hear a very different story from the brochure version. The odor from sargassum is similar to rotten eggs because the seaweed releases hydrogen sulfide gas as organic matter breaks down on the shore in the hot sun, and the masses of seaweed don’t just stink – they’re also unsightly and ruin the pristine appearance of Cancún’s white sand beaches. The problem is worsening year by year. In 2025, nearly 85,000 tonnes of sargassum reached shore – double the 40,000 tonnes that arrived in 2024.
The municipality closed the 2025 season having collected over 16,500 tons of sargassum, far higher than the 2024 level of 3,000 tons, with the increase attributed to climate variations and changes in ocean currents. The unpredictability is part of what makes it so disruptive. Various strategies, from raking manually to using barriers to catch the sargassum before it reaches shore, have been deployed to deal with the unprecedented waves of seaweed that have engulfed regions of the Caribbean and Mexico in 2015, 2018, 2019, 2020, 2021, 2022, 2024, and 2025. Increasing quantities of the seaweed have been washing ashore since 2011, posing a growing challenge to authorities working to keep beaches clean and safe for tourism.
5. The Coral Reef Is in Serious Trouble
The Mesoamerican Barrier Reef stretching along Cancún’s coastline was one of the city’s greatest natural assets. It is now one of its most threatened. Cancún is part of the Mesoamerican Barrier Reef, the second largest in the world, and irresponsible diving and snorkeling continues to disrupt the natural ecosystem. The 2024 Mesoamerican Reef Report Card painted a worrying picture. Coral health has been severely impacted by disease outbreaks and bleaching, reducing coral cover from 19% to 17%, with mortality continuing even after surveys concluded, and the 2023 bleaching event being the most severe on record, with approximately 40% of corals severely affected.
At the national level, Quintana Roo’s reefs are now dominated by fleshy macroalgae at 20%, turf algae at 30%, and increasing cyanobacteria at 5%, due to rising temperatures and declining water quality. The pressure from development is relentless. Poorly planned development of hotels and resorts in coastal areas can result in habitat destruction, pollution, and other negative impacts on biodiversity, and in the Mesoamerican Reef, tourism-related coastal development is rapidly expanding south from Cancún. Pollution, coastal development, and unsustainable fishing levels are eroding the ecological processes that maintain biodiversity and reef functioning.
6. Overtourism Has Eaten Away at Cancún’s Identity
In 1970, the area now known as Cancún had just 120 inhabitants; the population today has expanded to at least 900,000, and this degree of growth is rarely accomplished in a sustainable manner – it is, more often than not, chaotic, badly governed, and sometimes illegal. What was designed to attract visitors has slowly been consumed by them. Today, Cancún accounts for one-third of the entire country’s tourism revenue, a concentration that has made the city entirely dependent on an industry that is now showing signs of strain.
Some authorities have blamed low travel figures on cancellations due to protests, while others point to ongoing problems with power outages and Maya Train construction work, which created months of congested traffic in several areas. The infrastructure simply hasn’t kept pace with the growth. Riviera Maya hotel occupancy dropped to 44% in the summer of 2025, with reporting describing the season as “one of the worst low seasons in years” as more than half of all hotel rooms sat idle. Environmental degradation is at the core of the sustainability problems posed by mass tourism in Cancún, with the Hotel Zone, the nearby Barrier Reef, and the mangrove forests of Nichupté Lagoon all having been overtaken by tourism development.
