Dénia has about 20 km. of coast, in which its beaches stand out: To the north, the area of Las Marinas with the beaches of Punta del Raset, Les Marines, Les Bovetes, Els Molins, L'Almadrava (with area of boulders) and les Deveses. On the south coast, the area of Las Rotas with the Marineta Cassiana beach (sandy) and the rocky coves of Les Rotes, of great beauty, such as El Trampolí, La Punta Negra, Les Arenetes and La Cala.
All the beaches and coves of Denia stand out for the excellent quality of their waters. In most of them the Blue Flag flies, which is a recognition of the level of quality and excellence of conservation and services provided on the coast of Denia: lifeguard and surveillance, hammock service, waste collection, access for handicapped and some with parks for children.
Among the main places of interest, it is worth mentioning:
- The castle. It houses the Archaeological Museum, where you can see Roman artifacts found in the area. The Toy Museum is a journey through the city's toy legacy, while the Ethnological Museum, located in a semi-detached house from the s. XIX, contains works that narrate local life. Nearby are the church of La Asunción, in a baroque style, and the porticoed town hall.
- Montgó Natural Park. This park can be visited quietly and with a pleasant walk, it does not require great effort, its views and landscapes are excellent, both the views towards the interior, and the views when you arrive at the sea side. You can also see a variety of types of birds, highly recommended.
- The Denia fish market. Today, it is something that is not easy to achieve since, generally, it has been forbidden for tourists but it is a matter of trying. Fish arrives directly from the sea around 5:00 p.m. and then: the auction begins, it is surprising and fascinating!
