If your idea of a great vacation means being by the water, head to Illa Negra de lEst. No matter what you choose to do here, you're unlikely to tire of those lovely views.
You'll have to make your way to Ibiza Town to reach this water-surrounded land mass. If you're hoping to do some sightseeing afterward, why not check out Las Salinas Beach? It's within reach of Illa Negra de l'Est.
