Procida is connected to the islet of Vivara in the west, by a bridge.
Vivara has a surface area of 0.32 square kilometers and reaches its maximum height above sea level with a high ground of 109 meters.
Vivara is a protected oasis and all the typical Mediterranean vegetation is present in it. Vivara is connected to Procida by a bridge that, because of its currently being unsafe, obstructs visits.
Of volcanic origin, Procida is the site of now partly corroded ancient craters in the inlets of Chiaiolella, of Carbonchio and Pozzo Vecchio.

The proximity of Procida, like Ischia, to the Campi Flegrei allows us to presume that its geological age actually coincides with the origin of "fire earth", which is the ground which can be found in vast zones of Campania, constituted by yellow and grey “tufo”(tuff) and lava of basaltic nature.
Eruptive demonstrations in Procida actually date back as far as medieval times, feeding the myth of the giant called “Mimante” that sleeps under the island.
Procida reaches its maximum height at 91 meters above sea level with the promontory of Terra Murata.
The coasts are tall cliffs but they are alternated with bays and beaches between the prominences of Punta dei Monaci and Punta Pizzaco, Punta della Lingua, Punta Pizzaco and Punta Socciaro.
