If you happen to be on a holiday trip to Lanzarote and get bored by endless sunbathing and fiestas, try something different. From the northern tip take a ferry to the small island of La Graciosa. There is no entertainment other the hiking. The real island feeling. follow the coastline, cross the semi desert, climb some pumice cones and have nice views on neighbouring Lanzarotes eroded coastline.
