Puno Bay In Lake Titicaca is home to about 40 floating reed islands. They are home to the  Uros people who keep up with their age-old habits while trying to make an extra buck by inviting tourists on their islands.

As the reed decays a new layer has to be added every few months. The tortora reed is used as food, construction material and even medicine.
Walking on the islands is a special  experience and it feels a bit like walking on a waterbed.

When we visited Uros Chumi Island on a sunny morning in June 2008, there was still frost on the reed and in the shadow it was freezing. Ater all the altitude is a hefty 3800 meters above sealevel....

The locals walked around on slippers. They claim to have black blood, which is supposed to make them unsusceptible to cold. But most of them end up with arthritis.
