Spain's Foundation for Environmental Education (FEE) and its Spanish branch ADEAC published the 2026 Blue Flag list on 5 May 2026, and the headline figure for the Costa Blanca is unambiguous: the province of Alicante secured 95 Blue Flag awards, more than any other province in Spain. The Comunitat Valenciana, the autonomous region containing Alicante, took 174 distinctions — 22% of the national total and a gain of ten flags on 2025, according to figures reported by Olive Press, Idealista and TodoAlicante.
For anyone weighing a coastal property purchase between Dénia and Pilar de la Horadada, this is the clearest proof of the year that the Costa Blanca's water quality, beach management and environmental services rank at the top of European seaside benchmarks.
Costa Blanca on top — the 2026 numbers
Spain confirmed its position as the world leader for Blue Flag beaches, with 677 beaches awarded in 2026 — 33 more than in 2025. Including ports and sustainable tourism boats, the total reaches 794 distinctions. Within that national picture, the Comunitat Valenciana leads every Spanish autonomy, and within the Comunitat, Alicante province is the leader.
| Level | Blue Flag beaches 2026 | Change vs 2025 | Share of national total |
|---|---|---|---|
| Spain (national) | 677 | +33 | 100% |
| Comunitat Valenciana | 174 | +10 | 22% |
| Provincia Alicante (Costa Blanca) | 95 | — | 14% of Spain |
Key insight: Alicante's 95 flags put it ahead of every traditional Spanish beach destination — including Andalucía, Galicia and Cataluña. No other Spanish province matches the Costa Blanca on this metric in 2026.
Top municipalities in Alicante province
The flags are not evenly spread. Three municipalities dominate the provincial ranking, each with its own property character.
| Municipality | Blue Flag beaches | Blue Flag ports | Property profile |
|---|---|---|---|
| Orihuela (Orihuela Costa) | 10 | 1 | Volume market: apartments and townhouses, broadly the most accessible entry point on the southern Costa Blanca |
| Dénia | 7 | 2 | Mid-to-premium: villas in Las Marinas and Las Rotas, strong year-round demand |
| Torrevieja | 6 | 3 | High-volume rental market, wide range from budget apartments to seafront properties |
Beyond the top three, the Marina Baixa region combined with Calpe accounts for 18 Blue Flag awards on its own — covering the stretch from Altea through Benidorm and into the northern Costa Blanca, where premium villa demand has been strongest in recent years.
What changed in 2026 — newcomers and winners
The 2026 list contains several first-time additions on the Costa Blanca, all in coastal towns where property demand from northern European buyers has been rising:
- L'Advocat (Benissa) — first Blue Flag
- Puerto Blanco and El Racó (Calpe) — both first-time awards
- Cala Lanuza (El Campello) — first Blue Flag
Three further beaches regained the flag after losing it in earlier years:
- L'Arenal (Jávea) — the central urban beach of one of the most sought-after villa markets on the northern Costa Blanca
- L'Espigó (Altea)
- Tamarit (Santa Pola)
Not every result was positive. Cala Fustera in Benissa lost its Blue Flag in 2026 because water quality, while still good, dropped from the "excellent" classification that the FEE requires. (Cabanyal in Valencia city also lost its flag for the same reason, but that beach lies outside the Costa Blanca.) The Blue Flag programme audits water samples across the bathing season, and a single grade slip is enough to remove the distinction — which is precisely why the award carries weight.
Key insight: Cala Fustera's downgrade is a reminder that Blue Flag is not a permanent label. It is reassessed every year against beach safety, services, environmental management and — critically — bathing water classified as "excellent" under EU Directive 2006/7/EC.
Why Blue Flag matters for property buyers
Blue Flag is run by the Copenhagen-based Foundation for Environmental Education and assessed in Spain by ADEAC. To qualify, a beach must meet roughly 33 criteria across four areas: water quality (the strictest filter), environmental education and information, environmental management, and safety and services. Lifeguards, accessible facilities, waste management and posted water-quality data are all required.
For a property buyer, this matters in three concrete ways:
- Rental performance. Tourist platforms, OTAs and short-let agencies cite Blue Flag status in listings. Properties within walking distance of an awarded beach typically command higher nightly rates and stronger seasonal occupancy.
- Resale liquidity. A consistently flagged beach reduces the perceived risk of a coastal purchase. Buyers from northern Europe — the dominant demand segment on the Costa Blanca — increasingly screen for these certifications before viewing.
- Public investment signal. A municipality that retains or grows its flag count is one that is spending on bathing-water monitoring, beach access and lifeguarding. That maintenance flows through to surrounding property values.

What to watch for the rest of 2026
The Blue Flag list is renewed annually, and the 2026 results were measured against samples collected through the previous bathing season. The FEE will begin assessing the 2027 cycle as soon as Spanish beaches reopen for swimming, meaning the 95-flag headline for Alicante is a snapshot — not a fixed asset.
What is durable, however, is the trajectory. The Costa Blanca has held the leading or co-leading position among Spanish provinces in successive Blue Flag rounds, and the Comunitat Valenciana has now extended its national lead with a +10 gain in 2026. The 2026 newcomers — three of them in Calpe and Benissa, one in El Campello — confirm that the upgrade is happening in the same northern-Costa-Blanca corridor where villa demand has been most active.
The single 2026 loss within the province, Cala Fustera, is the more useful signal for buyers doing due diligence: beach quality is monitored, published and revocable. A coastline that adds four new flags and only loses one is not coasting on reputation. It is being measured — and, for now, it is the most-flagged province in the country with the most-flagged Blue Flag coastline in the world.
