Site description Two rocky islets (Roque de Dentro and Roque de Fuera) located off the north-eastern tip of Tenerife, which support drought-resistant and salt-tolerant vegetation. A copse of dragon's blood tree Dracaena draco exists on one of the islets. Human activities include gathering shellfish and boating.
