Dominican Republic at a Glance
Cordillera Central highlands, interior valleys, coastal plains and strong orographic climate contrasts define the Dominican Republic.
Physical geography

Climate pattern
The Dominican Republic has a tropical climate, but its complex mountain relief produces strong local differences in temperature and rainfall.
Water and landform context
The Cordillera Central contains Pico Duarte and gives rise to several of the country's major rivers, while other mountain chains and the Hoya de Enriquillo create additional relief contrasts.
