Cambodia’s Secondary Destinations Gain Ground as Southeast Asia Overtourism Redirects Traveller Demand

Southeast Asia is redrawing its tourism geography as visitor recovery intensifies pressure on established gateways and island hotspots. The region welcomed an estimated 144 million international visitors in 2025, according to the Asian Development Bank, marking a 13.4% annual increase. Meanwhile, ASEAN expects international arrivals to reach about 201 million by 2030, creating a powerful incentive to spread demand beyond crowded destinations. Indonesia received 15.39 million foreign arrivals in 2025, with Bali’s Ngurah Rai Airport alone handling 6.91 million. Vietnam recorded nearly 21.2 million international visitors, up 20.4%. The emerging strategy is therefore clear: develop secondary destinations, improve connectivity and redirect travellers before today’s alternatives become tomorrow’s pressure points.

The Region Is Rewriting Its Tourism Map

The tourism rebound has changed the central question facing Southeast Asia. The issue is no longer simply how to attract international travellers, but where those travellers should go once they arrive.

ASEAN’s latest tourism outlook shows the region had recovered to 92% of pre-pandemic international arrival levels by June 2025. Vietnam and Laos had already exceeded 2019 volumes, while Malaysia and Indonesia were close to full recovery. Tourism earnings also regained substantial economic weight, with domestic earnings reaching US$132 billion and tourism export revenues reaching US$150 billion in 2024.

That recovery brings an obvious structural challenge. Visitor growth concentrated around a limited number of airports, heritage sites, beaches and resort corridors can create congestion even when national tourism figures appear healthy.

The distinction matters for travellers because a country’s headline arrival figure tells little about pressure at an individual destination. A million visitors dispersed across several regions can create a very different experience from the same number concentrated around one island or heritage district.

Bali Reveals the Concentration Problem

Indonesia offers perhaps the clearest numerical illustration of tourism concentration. Official statistics show the country recorded 15,386,646 foreign tourist arrivals in 2025, with Ngurah Rai Airport receiving 6,907,585.

That means Bali’s principal international gateway accounted for about 44.9% of Indonesia’s foreign arrivals recorded through the listed entry points. Jakarta’s Soekarno-Hatta Airport handled another 2.76 million, while Batam received about 1.59 million.

The significance extends beyond Bali itself. When one tourism gateway captures such a large proportion of national international demand, infrastructure, accommodation, roads, beaches and public services face pressure that national totals can conceal.

Consequently, secondary Indonesian destinations such as Lombok and Flores become strategically important. Their value is not simply that they are quieter; it lies in their ability to offer different tourism products while potentially distributing spending across a broader geographic area.

Vietnam’s Growth Is Testing Capacity

Vietnam illustrates another dimension of the transformation. The country’s National Statistics Office recorded nearly 21.2 million international visitors in 2025, representing a 20.4% increase from 2024.

Air travel dominated the recovery. More than 17.8 million visitors arrived by air, accounting for 84.3% of international arrivals, while nearly 3.1 million entered by road and 273,900 arrived by sea.

This pattern has a direct travel implication. Air connectivity can rapidly transform a destination because new routes reduce access friction and make short stays commercially viable.

However, connectivity alone does not make a destination sustainable. New flights can accelerate hotel construction, road traffic, waste generation and pressure on sensitive landscapes if local capacity grows more slowly than demand.

The opportunity therefore lies in directing new connectivity towards a wider collection of destinations rather than repeatedly adding capacity to already saturated gateways.

Cambodia Is Diversifying Beyond Angkor

Cambodia provides an especially useful test of whether tourism diversification is actually happening. Official 2025 data recorded 5,569,752 international tourist arrivals, alongside 25.16 million domestic tourists and US$3.878 billion in international tourism receipts.

The country’s tourism statistics now distinguish Phnom Penh, Siem Reap Angkor, the Coastal Zone, the Eco-tourism Zone and other tourism regions. That geographical breakdown allows policymakers to examine visitor distribution rather than relying only on the national total.

The shift is significant for travellers seeking alternatives to heavily visited heritage circuits. Cambodia’s coastal and eco-tourism regions can broaden the country’s proposition, while community-based experiences can potentially retain more tourism spending locally.

Yet the same warning applies. A destination promoted as an “alternative” can become a new mass-market attraction once transport, accommodation and international marketing converge.

Bohol Shows How Alternatives Scale

The Philippines offers a revealing example through Bohol. The Asian Development Bank reported that Bohol attracted approximately 1.4 million tourists in 2025, up 4% from the previous year.

Connectivity is central to that growth. Bohol-Panglao International Airport recorded 2.22 million passenger arrivals in 2025, according to the provincial government, illustrating how rapidly an emerging tourism gateway can scale.

Bohol’s development also demonstrates why “hidden destination” is an increasingly unreliable label. The province has become a substantial tourism economy with international connectivity, established attractions and significant visitor infrastructure.

Its designation as the Philippines’ first UNESCO Global Geopark adds another layer. The destination now has to balance tourism expansion with protection of geological, marine and cultural assets.

Boracay Shows the Pressure Waiting Ahead

Boracay provides the contrasting picture. The island recorded 227,828 arrivals in December 2025, its busiest month of the year, according to Aklan Provincial Tourism Office data reported by the Philippine Information Agency.

The December figure included 182,913 domestic visitors, 40,179 foreign visitors and 4,736 overseas Filipino workers. Annual tourism-related revenues reached approximately ₱47 billion.

The figures demonstrate why tourism diversification cannot be judged purely by visitor growth. Boracay’s economic contribution is considerable, but intense seasonal concentration can create very different pressures from a similarly sized visitor base distributed across a larger region.

For travellers, that translates into practical differences in traffic, accommodation availability, beach conditions, excursion demand and the overall visitor experience during peak periods.

Langkawi Is Growing Into Its Own Test

Malaysia’s Langkawi demonstrates how an established secondary destination can move into a new stage. Official Langkawi Development Authority statistics show 3,215,730 visitor arrivals in 2025, up from 2,904,629 in 2024.

The data also reveal an important feature of modern tourism: visitors do not arrive through one channel. Langkawi’s 2025 traffic included jetty, airport, cruise, yacht and port arrivals.

That mix matters because different visitor segments place different demands on destinations. Cruise passengers may generate intense short-duration peaks, while longer-stay visitors create more sustained demand for accommodation, restaurants, transport and attractions.

For destination planners, diversification therefore means more than attracting additional visitors. It means balancing arrival channels, length of stay, geography and seasonality.

The New Tourism Strategy Is More Deliberate

The regional policy direction has also changed. ASEAN’s Tourism Sectoral Plan for 2026–2030 and related tourism strategies place greater emphasis on quality, sustainability, connectivity, digital transformation and broader destination development.

ASEAN’s sustainable tourism roadmap specifically calls for stronger destination monitoring, stakeholder participation and integration between tourism planning, land use and conservation.

The approach also recognises the importance of secondary cities and tourism areas. Earlier ASEAN planning explicitly identified stronger direct air links to secondary cities as a way to create new tourism destinations.

This represents an important evolution from conventional destination marketing. Instead of simply increasing visibility for already famous locations, policymakers increasingly need to determine where additional visibility can be absorbed safely.

What This Means For Travellers

The shift creates a useful opportunity for travellers. Secondary destinations can offer different landscapes, smaller tourism economies and more geographically dispersed experiences, while potentially reducing pressure on the most congested sites.

However, travellers should not assume that a destination described online as “hidden” remains lightly visited. Visitor statistics, airport traffic and hotel development can reveal whether an apparently obscure destination is already entering a rapid growth cycle.

This makes travel timing increasingly important. Visiting outside peak periods can reduce crowding, while staying longer and spending across smaller local businesses can distribute tourism value more widely.

The smarter alternative to overtouristed destinations is therefore not necessarily the most remote place. It is a destination where visitor growth, infrastructure and environmental management remain reasonably aligned.

The Hidden-Destination Paradox Is Emerging

The central paradox is becoming harder to ignore. The more successfully a destination is marketed as an escape from crowded tourism centres, the faster its own visitor numbers can rise.

That creates a repeating cycle across the region: a major destination becomes congested, governments promote alternatives, airlines improve connectivity, investors add accommodation, travellers follow and the alternative begins facing its own capacity pressures.

The policy challenge is therefore not to find one permanent list of secret places. It is to build a distributed tourism system where demand can move between destinations without overwhelming the next location.

That requires better visitor data, stronger local planning, environmental safeguards, transport investment and more sophisticated destination marketing.

A New Travel Map Is Taking Shape

Southeast Asia is entering a new tourism cycle with considerably more visitors and a more deliberate effort to redistribute them. ASEAN’s outlook projects roughly 201 million international arrivals by 2030, around 51% above the estimated 2025 level.

For travellers, that means the regional map is likely to become more varied. Bali, Boracay, Phuket and other established destinations will remain major draws, but airports, rail links, ferries and destination investment are creating new pathways into less concentrated tourism markets.

The real opportunity is not simply to replace one famous destination with another. It is to discover places where tourism remains economically valuable without becoming geographically overwhelming. As Southeast Asia moves towards 2030, the defining travel question may therefore shift from “Where is still hidden?” to “Where is growth being managed well?”
