Nature is also an attraction in many Heritage Cities. Indeed, Ibiza’s biodiversity has been declared a World Heritage Site by the UNESCO. In addition, the surrounding areas of Cuenca are a highlight with the gorges of the Júcar and Cabriel rivers, the source of the Cuervo River and the mysterious Enchanted City. In turn, enjoy the little known beaches and leafy laurisilva forests near San Cristóbal de La Laguna. Mérida is another fine example, surrounded by the Cornalvo Nature Reserve, Lácara Meadow and several wetlands.
