Uros refers to a group of floating islets located in Lake Titicaca off Puno, Peru as well as to the pre-Inca people who fashioned them, around 3,000 of whose descendants still inhabit and maintain the islands.
The islets are made of totora reeds, which grow in the lake. The residents use the reeds to create the conditions that ensure the islands stay afloat. The dense roots that the plants develop support the island.
Local residents fish, and hunt birds and graze their cattle on the islets. They also run crafts stalls aimed at the numerous tourists who land on the islands each year.
