Panama is the southernmost country of Central America. Situated on an isthmus, it connects the north and south part of America. It is bordered by Costa Rica to the north-west and Colombia to the south-east. Panama enjoys a rich Pre-Columbian heritage of native populations whose presence stretched back over 11,000 years. The country is best known for the US-built Panama Canal that was opened in 1914, and turned over to Panama in 1999. Small and amazingly diverse, Panama makes it possible for a traveler to visit not only two different oceans in one day, but be able to combine in less than a week a diversified natural experience (white sand beaches, cloud or rain forest, mountains or valleys) with a wide range of cultural experiences (seven Indian tribes, Afroantillian and Spanish Colonial culture, several historic monuments and a 300 year old World Heritage Site called Casco Antiguo (often referred as Casco Viejo, Panama Viejo, San Felipe or Catedral).
