Denia is a small tourist city located in the southeastern coast of Spain, to the north of Alicante. It has a population of around 40,000 although this can be more than doubled by tourism during the summer months.
Mail boats serve almost all populated in Denia, and are amongst the cheapest way to reach many areas, though far from the fastest or most comfortable. The government has a mailboat schedule of mailboat routes online  which may or may not reflect reality.
Beaches. One of the main attractions of Denia are the beaches. It has around 20 km. of coast divided in three parts: one sandy, the harbour and one rocky. If you go with kids it is more comfortable the sandy beach, which is in the northern part. All of them are equipped with foot showers and red cross volunteers. If you like diving it would be more interesting the rocky beach, like La punta negra or at the end of Les Rotes where there is a huge cliff.
Historical sites. Denia has a very long history coming even before the romans (when it was called Hemeroscopeion) and going through the moors until now. Almost everywhere in the town you can find ruins of those times. The castle is in good shape still keeping part of its main wall. There are also some old wind mills near Javea where you will have a great view as well. In the ethnological museum you will find all the information about the ancient and most recent history, when Denia was a big raisin exporter and had a big toy industry.
Historic town. Although most of the town is now full of apartments for tourists it still keeps some of its old charm. It is very interesting to walk around the old fisherman neighborhood, the harbour or the main street (Carrer Marqués de Campos).
Denia has a relatively big mountain (around 650 m.) which is very near the sea. It is now considered a nature reservation thanks to its Mediterranean flora and fauna. It has also some interesting caves like La cova de l'aigua.
As said before, if you do scuba diving or just snorkeling the rocky beach is the place for you. Over there you can see all kinds of Mediterranean fishes, squids, octopuses, sea urchins, etc.
Denia has many restaurants and multiple restaurant "districts", despite the town's small size. These range from small cafe style eateries serving fish and chips from English menus to tourists, to typical Spanish establishments with loyal local customers.
Many restaurants offer a menu of the day for between 8-12 Euros, often including multiple tapas for starters. Octopus, squid, mussels, prawns, scallops etc. are typical in starters and mains. Fish risotto is a common main dish, and makes a filling course that is both delicious and good value.
Head out to the Marina for more modern restaurants targeting international diners.
