A cattle guard 1 comprising a frame having two opposed frame members 2, 3 and a plurality of parallel bars 6a-I extending between the two opposed frame members, wherein: each end of each bar 4, 5 is rotatably supported by a respective frame member so that each bar may rotate about a respective longitudinal axis of rotation of that bar; each bar has a substantially planer surface which may be located uppermost by rotation of the bar; and wherein the cattle guard further comprises a linkage mechanism (12, 14 figure 3) connected to each of the bars and arranged to rotate the bars together between a position where the planar surfaces of each bar are uppermost and substantially coplanar, making it easier to walk over the cattle guard, and a position where the nonplanar surfaces are uppermost, making it more difficult to walk over the cattle guard, the cattle guard further comprising a locking means 8, (9, figure 2) for locking the bars in a position where the nonplanar surfaces are uppermost (figure 2).
