The present disclosure provides a pool ladder with an active protection mechanism. The ladder provides a switch positioned at a significant height from the ground such that children cannot easily reach the switch. When actuated, the switch unlocks a protective door for the ladder and the ladder can be moved to access the steps. As such, the ladder can effectively prevent children from unlocking the protective door and accessing the pool.

A ladder system is disclosed that includes a base unit comprising a base assembly and a pair of support legs extending horizontally from the base assembly, and at least one ladder module configured to be releasably mounted on the base unit to extend vertically therefrom. The base unit and ladder module together form a stable free-standing ladder in which the ladder module is cantilevered out from the base unit.
