The Ninglinspo is a stream in Belgium, tributary of the Amblève upstream from Remouchamps around Quarreux.

The valley of Ninglinspo is classed as an outstanding heritage area of Wallonia.

Its original name is the Doulneux, Dulnosus in Latin, found in the Charter of Sigebert III of 647 AD.

[1] At the top of the valley are the Crahay Rocks, named after J.N.Crahay, a former director of the Department of Water and Forests.

They are a puddingstone formed about 300 million years ago when the Ardennes were covered by sea.
