Javea the jewel in the crown Javea, or Xabia in the Valencian language, sits on the southeastern coast of Spain on the Costa Blanca. It is a small, historic town, virtually free of high-rise buildings. The clean, warm, blue Mediterranean Sea laps the many beautiful beaches and coves. Javea is often referred to as the jewel in the Crown of Costa Blanca. With its 20 kilometers of coastline and dramatic scenery it is easy to see why.
