The valley's main focal point is 16km northeast of Trinidad. Founded in 1750, the estate was purchased in 1795 by the dastardly Pedro Iznaga, who became one of the wealthiest men in Cuba through the unscrupulous business of slave trafficking. The 44m-high tower next to the hacienda was used to watch the slaves, and the bell in front of the house served to summon them.
Today you can climb to the top of the tower for pretty views, followed by a reasonable lunch (from noon to 2:30pm) in the restaurant-bar in Iznaga's former colonial mansion. Don't miss the huge sugar press out back.
