Vietnam
One of Southeast Asia’s fastest-growing tourism markets, Vietnam welcomed more than 21 million international visitors in 2025, setting a new record. That’s a striking number for a country that was still rebuilding its tourism sector just a few years ago. Much of the surge has been credited to relaxed entry rules that made the country far easier to visit than it used to be.
The pace of arrivals has outrun the slower work of upgrading roads, airport terminals, and coastal town utilities in places like Ha Long Bay and Phu Quoc. Local governments have announced new terminal expansions, but construction timelines rarely move at the speed of a tourism boom. For now, popular hubs are absorbing crowds that their existing infrastructure wasn’t quite sized for.
Japan
Japan’s tourism rebound has been one of the most dramatic recoveries anywhere in the world. The country recorded growth of 15.8 percent in international arrivals in 2025, continuing the momentum from 2024, when inbound tourism surged by more than 47 percent, supported by expanded air connectivity and the weak yen. Those are numbers most tourism boards would consider a dream scenario.
Japan welcomed a staggering 42.7 million international visitors in 2025, and the surge has brought challenges such as overcrowded popular destinations, elevated living costs, and strains on public infrastructure in cities like Kyoto and Tokyo. Narrow streets in historic districts, packed train platforms, and stretched hotel capacity have become common complaints from both visitors and residents. Local authorities have started experimenting with entry fees and visitor caps at some sites, though nationwide infrastructure investment moves far slower than the visitor curve.
Indonesia (Bali)
In 2025, foreign arrivals to Bali reached a historic high of 7.5 million visitors, proving the island’s enduring appeal despite intense negative media coverage in late 2025. That volume is remarkable for an island of roughly four million residents, and it has reshaped daily life across the southern tourism belt. Studies by local universities and hospitality research bodies have flagged issues such as water scarcity in popular southern districts, strain on waste management systems, traffic congestion, and loss of traditional landscapes to villa and hotel construction.
Bali’s government is now racing to catch up. A new waste-to-energy plant is set to begin construction in mid-2026 and aims to process 120 tonnes of waste daily upon completion. Plans for a second international airport in the island’s north are also underway, but until those projects finish, the existing roads, water networks, and waste systems remain under pressure from a visitor base far larger than they were built to handle.
Nepal
Nepal’s tourism recovery has been steady, but its most famous attraction has become a case study in overcrowding. In 2026, with the Tibet side of the mountain effectively closed to foreign climbers, nearly 500 permits were issued for the Nepal route alone, pushing numbers to their highest level in the mountain’s history. On a single day that spring, more than 270 climbers reached the summit from the Nepal side, with expedition operators estimating that more than 300 people were on the route simultaneously at one point.
The bottleneck isn’t only on the mountain. Tribhuvan International Airport, Kathmandu’s only international gateway, is operating at or above its capacity, limiting Nepal’s ability to scale tourism effectively, and this bottleneck restricts the number of incoming visitors while complicating efforts to expand the sector. Trekking routes near Everest and Manaslu are also showing signs of strain, with teahouses overbooked during peak season and trail damage worsened by shifting weather patterns.
Albania
Albania has quietly become one of the Mediterranean’s fastest-growing destinations, and the numbers back that up. Albania’s growth rate is estimated to be around 10 percent year over year. That kind of sustained expansion would strain infrastructure in a country twice Albania’s size, let alone one whose coastal roads and utilities were designed for a much smaller flow of visitors.
Officials are aware of the gap and are trying to close it. A new airport in Vlora, set to open in 2025/2026, aims to further boost connectivity, enabling easier access for European and international tourists. Until that facility and related upgrades are fully operational, coastal towns along the Albanian Riviera are absorbing crowds well beyond what their current roads, water supply, and waste systems were originally sized for.
Greece
Few places illustrate the mismatch between tourist demand and physical capacity better than Greece’s smaller islands. The strain on infrastructure in places like Santorini, where narrow cobblestone streets flood with thousands of arrivals every afternoon, has become a genuine crisis. Cruise ships in particular have turned quiet island towns into brief but overwhelming crowds within a matter of hours.
Athens has responded with some of the strictest visitor management rules in Europe. Greece has introduced a 20-euro levy for cruise passengers during peak summer months and established a daily cap of 8,000 visitors for Santorini to prevent the infrastructure from being pushed past its breaking point. Even with those caps, the underlying issue remains: island roads, sewage systems, and freshwater supplies were built for permanent populations a fraction of the size of peak-season tourist crowds.
Morocco
Morocco has emerged as one of Africa’s standout tourism performers over the past two years. Africa welcomed 81 million international tourists in 2025, an 8 percent increase from 2024, with Morocco and Tunisia particularly strong performers. Marrakech, Fes, and the coastal city of Agadir have all seen visitor numbers climb well past pre-pandemic levels.
Morocco benefitted from renewed marketing campaigns, enhanced connectivity, and improved tourism infrastructure, though the pace of investment has struggled to keep up with demand in the busiest medinas and resort corridors. Historic city centers, in particular, were never designed for the volume of foot traffic they now receive daily, and water resources in some tourist-heavy regions remain a longer-term concern as arrivals keep climbing.
Croatia
Croatia presents an interesting case because its national infrastructure is genuinely well developed, yet certain pockets still buckle under seasonal pressure. Croatia has long been one of Europe’s most visited destinations, attracting 20.7 million tourists in 2025. That figure reflects a country whose entire population is smaller than the number of tourists it hosts in a single year.
While this represents only a modest increase of 2.2 percent compared to 2024, Croatia’s tourism infrastructure remains one of the most mature in Europe, with well-established roads, ports, and transit links. Even so, historic old towns like Dubrovnik continue to see cruise-day crowds that overwhelm narrow medieval streets built centuries before mass tourism existed. The mismatch here isn’t about airports or highways so much as the physical limits of ancient stone alleys never meant to carry today’s foot traffic.
Spain
Spain keeps setting new visitor records even as protests against overtourism grow louder. Together, two months in 2025 saw 22.3 million tourists flock to Spain, far outstripping 2024’s figure of 21.8 million for the same period. Barcelona, Madrid, and the Balearic Islands have all absorbed a growing share of that traffic.
Spain has seen the most vocal anti-tourism movement in recent years, with residents pushing back against crowded neighborhoods, rising rents, and strained public services. Cities have introduced tourist taxes and short-term rental restrictions to slow the pressure, but the underlying housing and transit systems remain a step behind the pace of annual arrivals. It’s a pattern familiar to many popular European cities: the tourists keep coming faster than the infrastructure conversation can resolve itself.
South Korea
South Korea’s tourism numbers jumped sharply over the past two years, catching many local businesses off guard. South Korea recorded international arrival growth of 15.7 percent in 2025. That followed momentum from 2024, when inbound tourism in the country surged by more than 47 percent, supported by expanded air connectivity.
Growth at that speed tends to outpace planning cycles, and Seoul’s most visited neighborhoods, along with Busan’s coastal districts, have felt the difference in crowded transit and packed accommodation during peak seasons. Airports and rail links have generally kept pace better than in some other fast-growing markets, but smaller regional attractions have seen visitor numbers rise faster than local shuttle services, parking, and guide capacity can comfortably absorb. It’s a milder version of the same story playing out elsewhere: success arriving before the systems meant to support it.
Philippines
The Philippines shows a different, more uneven version of this problem. Even before the pandemic, the country lagged regional peers in foreign arrivals with 8.2 million foreign visitors, well below Indonesia’s 16 million, Malaysia’s 26 million, Thailand’s 40 million, and Singapore’s 15 million. Yet within the country, growth has concentrated in a handful of places rather than spreading evenly.
Foreign tourists remain concentrated in a few destinations, with the National Capital Region and Central Visayas, home to Cebu, accounting for over 60 percent of total foreign overnight stays. Unlocking the next phase of the Philippines’ tourism growth requires addressing long-standing infrastructure gaps that limit accessibility, competitiveness, and visitor experience. Boracay, Palawan, and Cebu have all experienced visitor surges that their local roads, ferry terminals, and water systems weren’t built to handle, even while the national arrival totals still trail regional rivals. The pattern across these eleven countries isn’t really about bad planning or poor management. It’s about success arriving faster than anyone expected, in places where roads, airports, water systems, and waste networks were built for a different, smaller version of the tourism economy. Some governments are pouring money into new terminals and utility upgrades right now. Others are experimenting with caps, levies, and seasonal restrictions to buy time. What ties these places together is a simple mismatch: demand curves that bend upward much faster than construction timelines ever can. Travelers heading to any of these destinations in the coming seasons will likely notice it firsthand, whether that means a longer airport queue, a crowded trail, or a beach town clearly built for fewer people than currently show up.
