Costa Rica–Panama border
The Costa Rica–Panama border is the 330 km international boundary between Costa Rica and Panama. 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 coast, through the Cordillera Central. The Echandi-Fernandez Treaty defined the current border as follows:[1]
- 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.
