The best kids paddle boards are quality inflatable SUP boards that get your little tikes, through to teenagers, involved in stand up paddleboarding.
A kids board is generally smaller in volume, which makes it easier to carry although full size adult boards that are shorter in dimension should be considered as they will allow your child many years of use for their SUP as they grow.
