A hidden garden accessible by using Crystal Heart to dash through a tunnel of spikes at the east end of the Waterways after defeating the Dung Defender, or through a tunnel connected to the Kingdom's Edge. The Grove houses the presumably deceased Isma, on whose corpse the Knight finds Isma's Tear, which allows the Knight to swim through acid.

- There is an unused key in the game's files labelled "Waterways_Key" which was presumably used to open Royal Waterways instead of the currently used Simple Key.
