Denia is a modern cosmopolitan city offering both visitors and residents a range of services. Dénia has a 20-kilometre coastline, made of small, beautiful coves. To the north there are the fine sandy beaches of Les Marines and Les Bovetes and the shingle beaches of Les Deveses and L' Almadrava (shingled) beaches which are craggy and rocky; to the south is the Les Rotes beach. Though the beaches are long, they are not enormous and generally appeal to family-type tourism.

Dénia is close to the sea, though some of its most characteristic features, such as the Mongó and the Natural Park, are situated on the border between Dénia and Jávea. In the surrounding area there are Gothic hermitages from the period of the Conquest and caves where potholing is carried out.
