Then finally away at 10.15 am (10:15) to San Isidro de los Destiladeros at Manaca Iznaga just 10 km from Trinidad. Here the attraction was the view from the top of the 3 story / 44m high bell tower of the grand Iznaga estate in the Valley of the Sugar Mills and the bell in front of the house served to summon them.
 
We had 35 min free time to climb the tower with its fabulous 360 degree view from the tower that the owners would watch the slaves at work below them. Walking there I saw a number plate with AKL on it (AKL is Auckland Airport where I live). I was looking for BSL my initials but to date had not seen one. The first letter denote the province that it comes from. Yes, there is a province which has a B as the first letter. I knew that Lisa had paid CUC$5 / US$5 / NZ$7.70 for hers in Havana on the first day. With this in mind. I asked the lady how much and she indicated CUC$5. I offered CUC$4 / US$4 / NZ$6.15 which she readily accepted. Perhaps I should have started the bargaining at CUC$3 / US$3 / NZ$4.60? When I was walking back to the bus, I saw that she had replaced the number plate with another one …. that had the same letters and numbers as mine AKL 751!

Trinidad's immense wealth was garnered not in the town itself, but in a verdant valley 8km to the east. The Valle de los Ingenios (or Valle de San Luis) still contains the ruins of dozens of 19th-century sugar mills, including warehouses, milling machinery, slave quarters, manor houses and a fully functioning steam train. Most of the mills were destroyed during the War of Independence and the Spanish-Cuban-American War, when the focus of sugar-growing in Cuba shifted west to Matanzas. Though some sugar is still grown here, the valley is more famous today for its status as a Unesco World Heritage Site. Backed by the shadowy sentinels of the Sierra del Escambray, the pastoral fields, royal palms and peeling colonial ruins are timelessly beautiful.
