From Hockai, you head towards the Hautes-Fagnes - Eiffel nature park to reach the infamous Cross of the Betrothed.

The Cross of the Betrothed is a monument on the plateau of the High Fens in Belgium, not far from the Baraque Michel. It is located on the ancient Gallic road "La Vecquée" and on the former border between Belgium and Prussia.

The cross was inaugurated in its present state on Sunday 20 September 1931 in memory of two young engaged couples who died in a snowstorm on 22 January 1871.

On the route, you can also see the former border marker 151 which marked the boundary between Prussia and Belgium.
