The 40-plus floating Uros Islands are perhaps the most photographed attraction on Lake Titicaca, famously constructed with springy totora reeds. The reeds are collected from around the shores of Lake Titicaca, and used to replenish the fragile islands every three months or so, as the bottom of the two-meter (6.5ft) totora mat slowly rots back into the lake. Thus, the islands change shape, size and even number as the centuries pass, anchored to the lake bottom but in many ways a completely separate world.
The Uros people are an ancient race, predating the Incas by millennia and, according to local legend, even the sun and stars. The “People of the Lake,” as they call themselves, once said that they did not feel the cold, thanks to their “black blood.”
