Lying on Spain's radiant Costa Blanca, Alicante exudes a rare beauty. Lovely Baroque buildings cluster around the historic central district. Marble plazas grace its broad waterfront boulevard, the illustrious Explanada de Espana. Pristine beaches like San Juan hug the shoreline. It's no surprise that Alicante is popular year-round. Venture to the grand Castle of Santa Barbara overlooking the city and walk from its high towers down into the dungeon. Stop for a glass of refreshing sangria in the Old Quarter. Behold the masterpieces hanging in the Gravina Museum of Fine Arts, a former 18th century palace.
