The fashionable Belgian watering place, Spa, is situated 1000 feet above the sea, in the centre of a circle of hills called the High Moors (Lea Hautes Fauges), a wild and desolate tract covered with peat-bogs and heaths, themselves some 600 to 800 feet above the town. Immediately above Spa, and opposite to it, there are two other distinct hills, of lesser height, the limits of which are definitely marked out by streams or deep valleys, and these, together with the “High Moors” and their rock, constitute the leading geographical features of the immediate neighbourhood.
