The Valley of Snakes is a small canyon found behind the Lost City. It is not as large as the surrounding lands and it houses the Claw Viper Temple where the vile Claw Vipers lay in wait; no monsters wander around outside. However, sometimes one or two Fire Towers can be found just before the entrance to the Claw Viper Temple. Technically this is where the vasts deserts of Act II 'end', as it's the furthest desert area players can reach by the connecting zones outside Lut Gholein. The last desert area players can explore in Act II is the Canyon of the Magi.
