This is the Delta de l'Ebre.
For just 25€ per person it's possible to arrange a boat ride out into the Delta to visit a local oyster farm.
You arrive at a barge floating out in the water. Just off the barge are rows of wooden planks with ropes hanging off them. The oysters grow off the ropes in the sea and at the small floating restaurant you're able to sample and taste them fresh.
Of course the tasting comes with a bit of cava, too!
Thanks to the Catalonia Tourism Board for inviting Traveldudes. All views are our own.
