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.
