Ash Lake is an optional area accessed by successfully reaching the bottom of The Great Hollow, through a tunnel past the Mushroom enemies. It is a wide, open space with seemingly endless views of Archtrees amidst deep, dark blue waters and below a sky of dense clouds. A large stretch of sand connects two Archtrees, and the shores abruptly end, leading to a watery grave.
Two bonfires are at either end of the area. One can be found shortly after arriving from The Great Hollow, and another is directly in front of the Stone Dragon, which is the only one in the area that can be warped to with the Lordvessel.

- If one continues through Ash Lake without defeating the Hydra it will attempt to follow the player. Once they pass the area about where the Giant Clams are, it will jump out of the water and fly across the beach to the other side to continue to pursue the player. It will then follow all the way to Arch Tree at the end, making confrontation with the Hydra unavoidable.
