The shimmering blue waters of Lake Titicaca are home to the famous, man-made Floating Islands of Uros. These islands and their dwellings, which date back to a pre-Incan time, are made completely out of totora reeds, a native bulrush plant that grows in the lake. With a guided tour, get to know the inhabitants that have formed a small community and learn how these islands stay afloat. During the afternoon, visit the island of Amantani and experience the unique culture of the locals.
