During the summer holidays we were at Borkum. Borkum is a German island in the German part of the Wadden Sea. The cool thing is, there is a ferry leaving from the seaport near the city, Eemshaven. We took the bus from the main station which runs during the summer months.
The island is very close to the Dutch coast. A a day trip to the island is really doable from Groningen. So yet another option when you’re in for a trip out of town of just one day.
Check the video we took of our little day trip to this nice island.
