, which includes the tropical moist forests

and the Galapagos Islands
. The region extends from easternmost Panama
to the lower Magdalena Valley of Colombia
, and along the Pacific coast of Colombia and Ecuador
to the northwestern corner of Peru
. It is bounded on the east by the Andes Mountains. The Tumbes-Choco-Magdalena Hotspot is 1,500 km long and encircles 274,597 km². Tumbes-Choco-Magdalena is near the Pacific Ocean.
