A balance training device for young children is revealed. The balance training device includes a footplate, at least one support disposed on a bottom surface of the footplate and at least one base connected to the support. The footplate, the support and the base are combined in different ways to form various playing modes including a see-saw mode, a ramp mode, a balance beam mode, etc. Thus the balance training device not only attracts young children to play but also improves their balance and trains their leg muscles in the play.
