Serpent Island

From Tardis Wiki, the free Doctor Who reference

Serpent Island was an island on Skaro infested with "hundreds of millions" of snakes of all sizes. (PROSE: The Dark Side of Skaro [+]Loading...["The Dark Side of Skaro (feature)"]) It was located in the vast Serpent Sea, with the island's snaked thought to be "dwarf mutations" of the region's sea serpents.

An Anti-Dalek Force expedition discovered this island on the dark side of Skaro. During their time on the island, the researchers found it was impossible to take more than two strides without stepping on a snake. (PROSE: The Dark Side of Skaro [+]Loading...["The Dark Side of Skaro (feature)"])

Serpent Island no longer existed in the era after the Last Great Time War, having been lost in geographic upheaval from Skaro's long history of war. Not enough evidence survived for Dalek historians to place the Island in relation to their modern Skaro geography.
