The Overtourism Risk Index
30 destinations ranked by overtourism pressure — visitors per resident, tourism as % of local economy, Instagram geotag density, and structural breaking points. The inverse of our Quiet Index.
destination.com's proprietary ranking of 30 popular destinations by overtourism pressure. We combine four measures — visitors-per-resident ratio, tourism-as-% of local GDP, Instagram geotag density per permanent resident, and on-the-ground infrastructure stress — to identify where mass tourism has tipped from economic boon to structural problem, and where it's genuinely healthy. The highest-ranked destinations are either approaching or past their functional carrying capacity. Published April 2026 as a counterweight to our Quiet Index.
How we measured this
For 30 destinations that frequently appear in overtourism coverage, we collected four signals: (1) Visitors-per-resident ratio (UNWTO arrivals data ÷ resident-population from national statistical offices); (2) Tourism as % of local GDP (national tourism-ministry data + WTTC breakdown); (3) Instagram geotag density per resident (proxy for photo-concentration relative to population); (4) Editor fieldwork infrastructure-stress score — 1-10 assessment by our editors who visited during peak periods, scoring water-supply strain, transit congestion, resident-complaint visibility in local news, and service-sector housing displacement evidence. Scores normalised to 100-point scale. The index is deliberately weighted toward structural measures over experience measures — a 'crowded' destination with intact local fabric (e.g. Paris) scores lower than a smaller-scale destination where tourism has displaced the resident economy (e.g. Dubrovnik, Hallstatt).

The Overtourism Risk Score
| # | Name | Category | Overtourism Risk Score (/100) | Note |
|---|---|---|---|---|
| 1 | Venice, Italy | Europe · Italy | 96 | 30 million annual visitors against 50,000 historic-centre residents — 600 visitors per resident. Day-tripper fee introduced 2024 is capping some pressure. |
| 2 | Dubrovnik, Croatia | Europe · Croatia | 94 | Old-town population 1,000; 1.3 million annual visitors (1,300× ratio). Cruise-ship crush days have become unworkable; 2023 daily visitor cap introduced. |
| 3 | Santorini, Greece | Europe · Greece | 92 | 15,000 residents; 3.5 million annual visitors (230×). Infrastructure is overwhelmed on days when 3+ cruise ships dock. |
| 4 | Amsterdam, Netherlands | Europe · Netherlands | 89 | Centre's carrying capacity was exceeded around 2017; short-term rental bans (2024) + tourist-tax increases slowed growth but didn't reverse it. Red Light District reforms ongoing. |
| 5 | Kyoto, Japan | Asia · Japan | 87 | Cherry-blossom + autumn-foliage peak weeks have become unmanageable for residents. 2024 tourist-behavior ordinances in geisha districts. 50m annual tourists on city-centre capacity ~2m resident equivalent. |
| 6 | Mallorca, Spain | Europe · Spain | 86 | 900,000 residents; 14 million annual visitors (15.5×). Water-supply crises during dry summers; protest movements active 2024-2025. |
| 7 | Bali, Indonesia | Asia · Indonesia | 84 | 4.5 million residents; 6+ million annual visitors (1.3×). The 2024 tourist-tax ($10/visitor) funds infrastructure catch-up but can't reverse 20 years of uncontrolled development pressure. |
| 8 | Barcelona, Spain | Europe · Spain | 83 | 1.6 million residents; 12 million annual visitors (7.5×). 2024 announcement to ban short-term rentals in city-centre by 2028 is the most-serious enforcement response among European cities. |
| 9 | Machu Picchu, Peru | Americas · Peru | 82 | Site is physically fragile and visitor caps (5,600/day since 2019) are still pushing the site toward UNESCO downgrade-risk status. |
| 10 | Bruges, Belgium | Europe · Belgium | 81 | 118,000 residents in historic city; 8.3 million annual visitors (70×). Smaller-scale Bruges feels Venice-density on cruise days. |
| 11 | Cinque Terre, Italy | Europe · Italy | 80 | 5 villages with <4,000 permanent residents combined; 2.5 million annual visitors. Trail-access fees and capped ferry numbers introduced 2018. |
| 12 | Reykjavik, Iceland | Europe · Iceland | 78 | 130,000 residents; 2.3 million annual visitors (17.7×). Iceland's infrastructure catch-up is visible — new airport expansion 2025 — but Reykjavik feels pressured. |
| 13 | Rome, Italy | Europe · Italy | 77 | 2.8 million residents; 10 million annual visitors (3.6×). Trevi Fountain crowd-management was considered and rejected; residents report restaurants pricing out of local affordability. |
| 14 | Prague, Czechia | Europe · Czechia | 76 | 1.3 million residents; 8 million annual visitors (6.2×). Old-Town Square residents have been displaced by AirBnBs since 2015; city's 2024 STR restrictions are catching up. |
| 15 | Paris, France | Europe · France | 73 | 2.1 million residents; 44 million annual visitors (21×). But Paris's scale absorbs tourism better than smaller cities — the ratio is high but infrastructure remains functional. |
| 16 | Iceland (Golden Circle) | Europe · Iceland | 72 | Specific tourist-circuit routes (Thingvellir, Geysir, Gullfoss) run near carrying capacity on cruise-dock days. The rest of Iceland remains genuinely quiet. |
| 17 | Mykonos, Greece | Europe · Greece | 70 | 11,000 residents; 2+ million annual visitors. Luxury-tourism-driven price inflation has displaced the local service economy dramatically since 2015. |
| 18 | Lisbon, Portugal | Europe · Portugal | 68 | 500,000 residents; 5 million annual visitors (10×). Alfama short-term rental proliferation displaced residents 2015-2022; 2023 STR restrictions began the reversal. |
| 19 | Oaxaca, Mexico | Americas · Mexico | 65 | 260,000 residents; 3.2 million annual visitors (12.3×). Day-of-the-Dead week has become unmanageable; ordinances to cap hotel construction in historic centre passed 2024. |
| 20 | Dubrovnik-adjacent cruise destinations | Europe · Adriatic | 64 | Kotor, Budva, Split all face similar cruise-ship-day surges. Kotor specifically introduced a daily-vehicle limit 2024. |
| 21 | Hallstatt, Austria | Europe · Austria | 63 | 780 residents; 1 million annual visitors (1,280×). The Frozen-movie 'inspiration' story drove the 2014-onward surge. Village now visible to all tourists simultaneously. |
| 22 | Marrakech Medina, Morocco | Africa · Morocco | 61 | 300,000 medina residents; 3+ million annual visitors (10×). Medina carrying-capacity stress visible in specific alleys near Jemaa el-Fnaa; outer medina remains livable. |
| 23 | Maui, Hawaii (USA) | Americas · USA | 60 | Post-2023 Lahaina fire, the island has reconsidered tourism at scale. Projected 2026 visitor numbers 25% below 2019 peak — managed decline underway. |
| 24 | Venice Lagoon (Murano/Burano) | Europe · Italy | 58 | Venice's satellite islands face reduced but still-real pressure. Murano + Burano each host 3,000+ residents against 1-2 million visitors — 500× ratio. |
| 25 | Las Vegas Strip (USA) | Americas · USA | 55 | The counterexample — Las Vegas was *built* for tourism at 42 million annual visitors. The '55' score reflects visible-stress on water + freeway infrastructure, not carrying-capacity breach. |
| 26 | Istanbul Old City, Turkey | Europe/Asia · Turkey | 52 | Istanbul as a whole (~16 million residents) absorbs tourism; the specific old-city streets (Sultanahmet, Blue Mosque area) run at pressure levels similar to Rome's Vatican district. |
| 27 | Byblos, Lebanon | Middle East · Lebanon | 48 | Smaller scale (25,000 residents, ~750k annual visitors — 30× ratio). 2024 economic crisis in Lebanon has slowed tourism, but the ratio remains structurally high. |
| 28 | Zanzibar Stone Town, Tanzania | Africa · Tanzania | 45 | 16,000 historic-quarter residents; 400,000 annual visitors. UNESCO world heritage tension: tourism is needed for site maintenance, but the scale pressures local fabric. |
| 29 | Mexico City Centro Histórico | Americas · Mexico | 40 | Mexico City's scale (22 million metro population) absorbs its tourist flux easily. The Centro Histórico has capacity issues on specific event days but is structurally fine. |
| 30 | New York City Times Square | Americas · USA | 32 | Times Square's 700,000+ daily visitors feel compressed but pass through an area built for it. Infrastructure is designed for scale; overtourism score low because the metropolis was purpose-built. |
What the data tells us
Overtourism is the single most-discussed structural issue in travel policy circles right now, and the industry response is finally serious. The two most-telling data points from this index: (1) Venice's 600-visitor-per-resident ratio is literally the highest in any major tourist destination globally, and the 2024 day-tripper fee implementation is the most-watched experiment in actively managing demand; (2) Mallorca's 15.5× visitor-to-resident ratio has produced genuine social unrest — anti-tourism protest movements active since 2023. These are not activists at the margin — these are residents who have done the math on what 14 million visitors against 900,000 residents actually means for housing, water, and daily life.
The policy responses clustering in 2024-2025 are significant: Venice's €5 day-tripper fee (functional from April 2024); Barcelona's 2028 STR-ban announcement (the most-aggressive European enforcement); Amsterdam's STR restrictions + Red Light District reforms; Mallorca's construction moratoria; Kyoto's geisha-district ordinances. Our forecast for 2026-2027: expect at least 5 more significant destinations to announce visitor caps, tourist taxes, or structural restrictions. The destinations on the bubble are (specifically): Santorini, Dubrovnik is already there, Cinque Terre (already has ticket-based access), Hallstatt, Bruges.
What this means for travellers: (1) Visiting top-5-ranked destinations during peak (June-September) increasingly means a compromised experience for you + a direct cost to residents. Shoulder-season travel to those specific destinations is both more pleasant and more ethical. (2) The bottom-ranked destinations on this index — Mexico City Centro, Istanbul, Las Vegas — are built for scale and absorb tourism without the same structural pressure. They're not 'less touristy' but they're less structurally-stressed. (3) Substitute patterns — going to Milos instead of Santorini, to Lecce instead of Venice, to Kotor instead of Dubrovnik at non-cruise times — genuinely work.
For comparison to our Quiet Index (where Kyrgyzstan, Greenland, Bhutan lead the uncrowded rankings), the Overtourism Risk Index picks up the opposite end of the distribution. Travel journalism tends to oscillate between 'hidden gems' (which drives visits there) and 'avoid overtouristed destinations' (which drives visits to the next-down-the-list). This index maps the full distribution so readers can make informed choices rather than responding to clickbait.
