Cristal Hotel is situated near the well-known Estuary of Villaviciosa. It is famous for its special drink "sider", and has beautiful beaches and stunning scenery. The Estuary of Villaviciosa is a striking, natural spot, combining elements from the river and the sea. The main characteristics of this Estuary of great environmental value are the halophilous and sub-halophilus vegetation, its important fauna, especially ornithological and the great variety of units generated within its boundaries. The Estuary flows into Tazones, between the beaches of El Puntal and Rodiles and gradually narrows into the centre of Villaviciosa itself, when it reaches The Porreos, name given to the pieces of land found in the area reclaimed from the sea where sub-halophilus meadows can be found with highly interesting canals and ponds. The forests surrounding the valleys are specially recommended for hiking.
