A putting green simulator consists of an inflatable body, an upper putting layer which is arranged to distort under pressure when inflated, an artificial turf layer attached or attachable to the upper putting layer so as to define a putting surface over which a golf ball may be putted, and at least one golf ball receiving cup or aperture defined in the putting surface. The arrangement is such that distortion of the upper putting layer causes contours in the putting surface so as to simulate the contours of a conventional putting green. The artificial turf layer is provided as interchangeable synthetic mats or carpets corresponding to a range of putting speeds as measured by a conventional stimp meter.
