Environmental protection, enhancement, and sustainability are the ingredients of a recipe that offers the Asinara National Park the best development prospects . The island promotes environmentally friendly tourism, as demonstrated by its commitment to the European Charter for Sustainable Tourism, recording over one hundred thousand visitors in the 2025 season, with a strengthening of foreign visitors and a preference for experiential tourism. This is confirmed by data processed by the Eagler company, which shows a stabilization trend following the 2024 peak in arrivals. Out of 20,186 users monitored through the Heart of Sardinia app, a progressive stabilization of tourism trends is evident, with the composition of visitors by origin remaining essentially stable compared to 2024, with a slight increase in local tourists (Sardinia and Italy) and a marginal reduction in some foreign markets (Germany and France).
Among Italian visitors, Lombardy and Lazio remain the main regions, followed by Tuscany, Veneto, Piedmont, and Emilia-Romagna. Sardinian visitors come primarily from the municipalities of the Metropolitan City of Sassari (53.4%), and partly from the province of Northeast Sardinia (24.8%). The main tourist entry points are Alghero Airport and Porto Torres, which continue to dominate arrival rates. Access to the park continues to be concentrated between the two main embarkation points: Stintino and Porto Torres, with the former prevailing during peak months (July–August), while Porto Torres recovers during off-peak periods. Figures provided by some facilities on the island show small variations for 2025 compared to the previous year. The Cala Reale Sea Observatory saw a significant increase in visitors, from 25,000 in 2024 to 28,080 in 2025, while the Whale Skeleton exhibition increased from 500 visitors in 2024 to 1,500 in 2025. Conversely, the Cala d'Oliva Memory Observatory saw a decline, from 44,650 visitors in 2024 to 40,314 in 2025, a reduction of approximately 3%, likely related to some critical issues with the shuttle bus passenger transport service and the temporary closure of the Hostel, a hospitality facility undergoing safety improvements.
On the island, where several renovation and restoration projects are underway on historically significant buildings, data shows an increase in visitor numbers at Cala Reale, which have become true attractions, such as the Casa del Parco and the Marine Observatory. Visitors are particularly interested in experiential tourism. In 2025, the popularity of more accessible outdoor experiences (cycling tourism) and activities related to the park's marine area (chartered sailing excursions and fishing tourism) remained stable.
Economic activity in the wider Asinara Gulf area has also not seen significant changes, with visitors generally being more likely to associate a visit to Asinara with economic activity in the area. This is the so-called "intensity effect," which draws the island into tourists' preferred itineraries, with peaks in consumption during the summer months.
Regarding the analysis of visitors to Asinara who, in the 24 hours preceding or following the visit, were present at other attractions (tourist and seaside) in the area, the trend remained essentially unchanged: La Pelosa beach and Porto Conte Park maintained the highest percentages.
The 2025 data report encourages strategic choices geared toward quality tourism, combining enjoyment and conservation, while maximizing the economic impact on the Gulf of Asinara.
