EDEN is the acronym for European Destinations of Excellence, a project promoting sustainable tourism development models across the European Union. The key feature of the selected destinations is their commitment to social, cultural and environmental sustainability. The recipients of the award are emerging, little known European destinations located in the EU Member States and EU candidate countries.

Each year, a new theme is chosen for this award. In 2010, the theme of excellence was announced to be "Aquatic Tourism" for which Nin was recognized.
