Leaving from our campsite in the morning, we walked 10km north toward Rantum.

Initially we followed the main road. But veered off a little to have a look at the marshland. Most of this is fenced off as it is a bird sanctuary. The island is at its narrowest here, so it was only a short distance from the open North Sea to the west and the Wadden Sea mudflats to the west.

We wandered past the LORAN-C radio mast. This is the only such navigation transmitter in Germany, but its use has diminished in recent years, with the rise of GPS technology.

Arriving in Rantum, it was striking how new the houses were. It seemed to be predominantly holiday villas, built with a vernacular thatched roof, but most appearing to date from the 1980s or later. I had read that Rantum had been rebuilt a number of times through its history after severe storm flooding. I wondered whether this explained the lack of old buildings.

We found very little to do in Rantum. After a meal of labskaus at a restaurant near the sea, we caught the bus back to Hörnum.
