The municipality with a land mass of 55,27 square km, borders the towns and cities of Alicante, San Juan de Alicante, Muchamiel, Busot, Aguas de Busot, Orcheta and Villajoyosa.
Campello has 23 km of coastline of which Muchavista beach is the most outstanding spot (the beach links Campello to San Juan, part of Alicante) and the beach is directly connected to the town centre. Between the two beaches is the mouth of the river Monnegre, called “Dry river” in the Huerta de Alicante area, whose flow generally stops before reaching the town although it does fill up during periods of intense rainfall and flash floods.
On this stretch of coastline are also well known spots such as Calle del Mar beach ,next to the promenade (in the town centre), the coves at Baños de la Reina, la Isleta, and at Coveta Fumá -a small resort which has undergone urban redevelopment in recent years. The terrain of Campello is flat in the south whilst the northern zone lies in the foothills of the Cabezón de Oro, which reach a height of over 310 metres.
