Alicante
It is definitely worth spending some time in Alicante (Alacant). With beaches, nightlife, a lovely renovated old town and, if you're there at the end of June, a great fiesta, Las Hogueras.

Alicante, in Valencia, is the main city of the Costa Blanca and has an airport.
As well as the town with its wide avenues and seafront Paseos full of cafés and bars there is the Castillo de Santa Barbara standing high above Alicante's beach. A shaft has been cut straight up the hill with a lift up to the Castillo. The castle is a medieval fortress but there are also Roman remains on the site. After exploring the Castillo relax in the castle gardens, the Parque de la Ereta. The views of the city are not to be missed.
Alicante's Museo de Arte Siglo 2000 has works by Picasso, Miro, and Dali. There is also a good archeological museum.
