Serpentshrine Cavern is the raid wing of Coilfang Reservoir, where Lady Vashj has made her lair. It is a 25-man raid instance with six bosses, culminating with Lady Vashj herself. There is no longer an attunement to zone into this instance.

For most raids, Serpentshrine Cavern will come only after the raid has been farming Karazhan as well as Gruul's Lair.
