15. Laguna Verde
The Laguna Verde covers an area of 1700 ha, and a narrow causeway divides it into two parts. It is at the southwestern extremity of the Eduardo Avaroa Andean Fauna National Reserve and Bolivia itself. It has mineral suspensions of arsenic and other minerals which renders colour to the lake waters. Its color varies from turquoise to dark emerald depending on the disturbance caused to sediments in the lake by winds.
