Castle's Waterway

Castle Town Sewers, also known as the Castle's Waterway and the Underground Waterway, is a location in. As its name suggests, it is the underground waterway of Hyrule Castle Town which connects to Hyrule Castle. Link only explores the Sewers in his wolf form.

Features and Overview
When Link is captured by the Twilit Messengers, he is imprisoned in a jail cell inside the Castle Town Sewers. Here, Link meets Midna for the first time, who frees the young hero. Midna tells Link that she wishes to introduce him to someone, and the two begin searching for an exit from the sewers. As Midna and Link traverse the Castle Town Sewers, they must lower and raise the water levels of the underground passageway in order to eventually exit through a small tunnel at the far end. At the edge of the Sewers is a long, spiraling staircase which Link must cross via ropes to reach the rooftops of the castle. By jumping from rooftop to rooftop, Link eventually reaches the tower in which Princess Zelda is imprisoned.

Later in Link's quest, Midna is gravely injured by Zant, and Link must once again go through the Sewers to take the dying Midna to Princess Zelda. He enters them through a secret passageway from Telma's Bar, which leads to Jovani's House and then to the underground waterway. Here, Link explores a new section of the Sewers which is infested with Skulltulas as well as cobwebs that he must burn in order to proceed. This connects to the area in which Link was imprisoned near the beginning of his quest.

Once Link reaches Princess Zelda for the second time, he will be unable to return to the Castle Town Sewers again.
