A ramp system includes at least one ramp component. Each ramp component includes a front surface provided a user sliding thereon and a back surface opposite to the front surface and facing to the ground. The at least one ramp component each has a connecting portion including at least one connecting block and at least one connecting recess spaced by the connecting block. The at least one connecting block and the at least one connecting recess can be assembled with that of other ramp components at random to create a skating facility. These ramp components are easily assembled for use and disassembled for storage and transport.
