It passes through the most picturesque scenery in Belgium and is remarkable for its sinuous course, its length of 120 m.
It comprises a sinuous strip of territory measuring between 750 and 800 m.
The south-eastern like the northwestern corner of the island is watered by a considerable number of short mountain streams. The one great river of the eastern versant is the Kutei or Mahakan, which, rising in the central mountains, flows east with a sinuous course and falls by numerous mouths into the Straits of Macassar.
In nearly all instances the rivers, owing to their sinuous course, are much longer.
It is about a mile east of Torquay harbour and is of a sinuous nature, running deeply into a hill of Devonian limestone.
