"Locks 31-32, or Viñalta locks, are part of the 49 locks on the Canal de Castilla, 18 of which are on the southern branch. The Viñalta locks have the special feature of being grouped consecutively, allowing the steepest gap in this area to be overcome. The locks are oval type and belong to the first stage of construction of the Canal's hydraulic works. They have gates at the bottom and mechanisms that allowed them to be closed using a guillotine system.
This set of locks is located 1.5 km from the Castilla Canal Dock, in a pleasant walk along the secondary branch that connects the dock with the Canal itself. "
