Union Lido, located in Cavallino-Treporti on the northern edge of the Italian Adriatic, remains the largest campsite in Europe in terms of capacity. Specialized Italian and German articles dedicated to megacampings published between 2023 and 2024 consistently cite it as a historical and current reference in terms of size, ahead of La Ballena Alegre in Spain or the large French campsites in the Landes region.
Cavallino-Treporti: why this site concentrates the megacampings of the Adriatic
The coastal strip of Cavallino-Treporti, between the Venice lagoon and the Adriatic Sea, brings together an unparalleled density of very large campsites over just a few kilometers. The sandy, flat ground, bordered by pine forests, offers a considerable usable area without the constraints of relief.

The immediate proximity to Venice generates a constant flow of tourists from April to October. Campers who want to visit the city without paying for Venetian accommodation find here a logical base, less than an hour from St. Mark’s Square by vaporetto.
Union Lido takes advantage of this configuration better than its neighbors. The campsite has a direct access to a private fine sandy beach, a water park, several restaurants, and sports facilities that make it a self-sufficient destination. The five-star rating reflects this level of infrastructure, comparable to that of an integrated resort rather than a traditional campsite.

To discover the largest campsite in Europe in detail, the opening period generally extends from spring to autumn, with a peak in attendance in July-August that requires booking several months in advance.
Train and shuttle access: the car is no longer the logical reflex
Since 2023, the large campsites of the Adriatic, led by Union Lido, have strengthened their private shuttles from nearby train stations and airports. This shift responds to the increase in arrivals by train and low-cost flights rather than by personal car.
Organized transfers from the Mestre and Venice train stations or the Venice-Marco Polo and Treviso airports are now bookable online, directly within the campsite’s booking process. The Italian tourist press reported this development as early as 2023.
We recommend the train + shuttle combo for three concrete reasons:
- On-site parking for two weeks represents a significant additional cost, especially in high season, where the shuttle is often included or charged at a modest flat rate.
- The Milan-Venice train line serves the Mestre station in a few hours from most major cities in northern Italy, with TGV connections from France via Turin.
- Treviso Airport, served by several European low-cost airlines, is less than an hour’s drive from the campsite, including transfer.
This multimodal accessibility distinguishes Cavallino-Treporti from large French (Landes, Hérault) or Spanish (Costa Brava) campsites, which are often more dependent on individual cars due to the lack of nearby train stations.
Locations and accommodations: what size really changes in the stay
A campsite of this scale is not managed like a family campsite with a few hundred pitches. The size has direct effects on the daily experience, both positive and negative.
The first tangible advantage is the diversity of pitches. Union Lido offers classic plots for tents and caravans, recent mobile homes, lodges, and high-end bungalows. This segmentation allows for the coexistence of very different budgets and expectations on the same site, which would be impossible in a medium-sized campsite.
The water park and leisure facilities (sports fields, children’s clubs, entertainment) reach a scale that more modest campsites cannot finance. The pool is not a single basin but a complex with slides, a paddling pool, and swimming areas.
In contrast, the density in high season transforms certain areas into a small urban village. The main paths are busy, the ambient noise increases, and the feeling of nature significantly decreases in the most central areas. To find calm, we recommend the pitches on the outskirts of the site, near the pine forest, which are farther from the entertainment but much quieter.
Campsite in Italy or France: the match on very large capacities
France has several very large campsites, particularly in the Landes and along the Mediterranean coast. Some exceed a thousand pitches. Their strong point lies in the quality of water spaces and the variety of activities for children.
The difference with Union Lido lies less in the area than in the integration into a broader tourist ecosystem. Cavallino-Treporti provides access to Venice, the islands of Murano and Burano, and the beaches of the Adriatic coast, all without a car. No French campsite of comparable size offers a cultural heritage of this level within an hour.
Spanish campsites on the Costa Brava, like La Ballena Alegre, compete on the beachside. Their natural setting is often wilder. However, train access remains more complicated from northern Europe, and organized shuttles from airports are less systematic than in Veneto.
The choice between these destinations depends on the type of vacation sought. For a stay focused on beach, pool, and pure relaxation, the Landes or Costa Brava hold their own. To combine camping and cultural visits without multiplying car trips, the position of Cavallino-Treporti remains hard to match in Europe.
Mass camping is evolving towards a model of accessible resort, where the size of the site is no longer sufficient to justify the trip. What makes the difference today is the ease of access without a car and the richness of the immediate environment. On these two criteria, Union Lido remains ahead.
