The Ebro Delta National Park is the second largest wetland in the Mediterranean, the Camargue in France is the largest.
We stayed at a private aire which is free to stay the night at. It has dedicated motorhome services which are available for 3 euros. if you do need to use the services you collect the key and pay for the use in the restaurant next door. https://www.searchforsites.co.uk/marker.php?id=18094

There are only a couple of towns in the Ebro Delta National Park. We stopped at Deltebre and went to Lidl to get some shopping. There is also a very reasonably priced fuel station opposite and we paid 1.07 euros per litre for diesel. On the opposite side of the road to Lidl there is also a Dia Maxi supermarket and we spotted a washing machine and dryer in the car park.

The Ebro Delta National Park is home to many species of floral and fauna and about 95 species of birds. Also over 300 different species of migratory birds pass through each year.

22,000 hectares are used to grow rice. Delta de l’Ebre rice is considered a quality ingredient throughout this part of Spain and many famous local chefs serve Delta de l’Ebre rice in their restaurants.

Since 1992 a colony of pink flamingos have been settled in the Delta de l’Ebre where they are visible throughout the year, although they’re most visible in the winter. This is now the only place in Catalonia where the birds reproduce and some 2711 pairs were counted in 2017, the highest number on record yet. Unfortunately we didn’t get to see any flamingos while there.
The Ebre Delta is very unique and it was great to spend a couple of days off the beaten track.
