El Camino Real, literally translated as the royal road, is referred to in English as the King's road or the King's highway.
El Camino Real is a road crossing the isthmus through the jungle of Panama, connecting Panama city and the city of Balboa (also the city of Portobelo).
Vasco Nunez Balboa was the first Spaniard to hack his way through the isthmus of Panama and stressed the need to build a road connecting the two oceans. Later the King of Spain commissioned to have the road built using Panama locals as slaves. The Spanish used the road to get the gold from Inca raids either from the Caribbean to the Pacific Ocean where the gold could be sailed to California or from the Pacific to the Caribbean where it could be sailed to Spain. It was this same road that the Pirate Henry Morgan used in 1672 to sack Panama City.
Until the completion of the Panama Transcontinental Railroad in 1856 anyone that wanted to cross Panama had to travel by mule or foot through the jungles of Panama
