For a singular Riemannian foliation $\mathcal{F}$ on a Riemannian manifold $M$, a curve is called horizontal if it meets the leaves of $\mathcal{F}$ perpendicularly. For a polar foliation $\mathcal{F}$ on a unit sphere $\mathbb{S}^{n}$, we show that the horizontal diameter of $\mathbb{S}^{n}$ is $\pi$, i.e., any two points in $\mathbb{S}^{n}$ can be connected by a horizontal curve of length $\leq\pi$.
