The Chocón Machacas Protected Biotope is a protected nature reserve in eastern Guatemala. It is located in a densely forested area covering the lower reaches of the Chocón Machacas River basin and the northern shores of the Río Dulce-Golfete Dulce system.
This area harbors a very complex hydrologic system that includes the sea, a lake and several
rivers, all of which bestow upon it very special characteristics.
