Costa Rica–Panama border

The border between Costa Rica and Panama is 348 km (216 mi) long. The border in its present state is demarcated by the Echandi-Fernandez Treaty of 1941.

The border between the two countries runs between the Pacific and Caribbean coasts, through the Cordillera Central. The Echandi-Fernandez Treaty defined the current border as follows:

  • It begins at the mouth of the Sixaola River in the Caribbean Sea, following the valley of this river to its influx in the Yorkin River.
  • Thence continuing upriver on the bottom of the river valley up to the parallel in the length 9°30'N.
  • Then continuing in a straight line to the meridian at 82°58'10"W.
  • From there it continues south along this meridian to the summit of the Cordillera de Talamanca, which separates the Caribbean waters and Pacific waters.
  • It follows this ridge to Mount Pano where it meets the ridge that divides the waters of the tributaries of the Golfo Dulce and the Charco Azul Bay.
  • From here it follows the ridge until the end of Punta Burica on the Pacific Ocean.
