We had an inspection trip to Emden to see if we wanted to go there and were recommended a trip to Greetsiel.
It was such a cozy place. We were there on a very busy day in May and there were people everywhere.
I noticed that most people had backpacks with a thermos and some lunch and good walking shoes so I think this is a super picnic destination, although there were many charming restaurants.
Greetsiel is a great place for a Sunday walk, more info her.
