The most interesting sight is the Museo de Ciencias Naturales Sandalio de Noda. In a wild, neogothic-meets-Moorish mansion built by local doctor and world traveler Francisco Guasch, this museum (called Palacio de Guasch by locals) has everything from a concrete T-Rex to a stuffed baby giraffe. Come for the flowering garden, architectural details and friendly specialist staff.
Cueva Punta del EsteThe Cueva de Punta del Este has been called the 'Sistine Chapel' of Caribbean Indian art. Long before the Spanish conquest (experts estimate around AD 800), Indians painted some 235 pictographs on the walls and ceiling of the cave. The largest has 28 concentric circles of red and black, and the paintings have been interpreted as a solar calendar.
Valle de los IngeniosThe ruins of dozens of ingenios (small 19th-century sugar mills), including slave quarters and manor houses, are scattered throughout this valley. The royal palms, waving cane and rolling hills are timelessly beautiful. The prime sight is Manaca Iznaga, an estate purchased in 1795 by the dastardly Pedro Iznaga, who became rich by trafficking in slaves.
Mirador de BacunayaguaAbove the Vía Blanca on the border of Habana and Matanzas Provinces is the Mirador de Bacunayagua, an outlook over Cuba's longest (313m) and highest (100m) bridge. This is one of the best views in Cuba, with densely wooded valley chasms backed by blue waves. All tour buses between Varadero and Habana stop here.
La Jungla de JonesLa Jungla de Jones is a rich and verdant botanical garden containing over 80 varieties of tree. The highlight of La Jungla is the aptly named Bamboo Cathedral, an enclosed space surrounded by huge clumps of craning bamboo that only a few strands of sunlight manage to penetrate.
