First stop in the valley of "Los Ingenios" (14 km before Trinidad) at La Torre Manacas-Iznaga. This 45 meters tower is the symbol of the former glory of one of the most powerful families in the sugar aristocracy. The tower made it easier to keep a watchful eye on the slaves working in the sugar fields. There is a small market at the base of the tower. The big bell which was once at the top of the tower.
