Langeoog (Low German: Langeoog) is one of the seven inhabited East Frisian Islands at the edge of the Lower Saxon Wadden Sea in the southern North Sea, located between Baltrum Island (west), and Spiekeroog (east).
This walking tour leads once over the large dikes of the island. First in the direction of Oostende, then towards the harbor and past the Flinthörn nature trail in the village.
