Riumar is a privileged place as it is located between the mouth of the Ebro river and the sea, within the Delta de l’Ebre Natural Park. It has got a beach formed by natural dunes, about 4km long, extending along the eastern part of the Delta. Within the limits of the Delta de l’Ebre Natural Park, walking through this area allows you to come into direct contact with nature and the birds that inhabit there. You can follow the coast until you reach the Garxal area, which is the mouth of the river. It is an ideal place to observe flamingos.
