Ruins - none from the pre-Columbian days unless you count the Caritas Indias (indigenous rock carvings) near Lago Enriquillo in the SW, or Taino cave paintings in places like Cueva de las Maravillas near San Pedro, where photography is not allowed.
Post Columbian ruins:
- early Spanish settlement which was later abandoned, La Isabela on the north west coast;
- early Spanish settlement destroyed by an earthquake, La Vega Real in the centre of the country, near the modern city of La Vega;
- early sugar mill, Ingenio de Nigua, to the west of the capital.
In the capital itself the Colonial Zone boasts several ruins: Hospital San Nicolas de Bari, Convento de San Francizco and Fortaleza Ozama.
Waterfalls:
- Salto el Limon in the NE near Samana.
- Damajagua (aka Siete Aguas) near Imbert in the north.
- Aguas Blancas near Constanza
- Salto Jimenoa near Jarabacoa.
(To name just a few...)
Sites of general ecological interest:
- Lago Enriquillo in the SW, semi arid region with interesting wildlife and desert scenery.
- Parque Nacional Los Haitises in the NE.
- Samana Bay for whale watching - you will be here at just about the right time.
All the above score pretty high on the photogenic scale, but you have to be lucky as well as skillful to snap those whales!
