The Fantastic
Floating Islands of Titicaca


Starting shot
The Uros people of Lake Titicaca have a unique way of life - they build their own islands, float them on the lake and then proceed to live on them. Here is a glimpse of their world, where their homemade "islands" are truly "in the stream".

Floating islands? It may sound like something out of a Jonathan Swift novel, but to the Uros people it is a fact of every day life. This small tribe of South American indigenous people retain a great deal of a culture that goes back millennia and one whose unique domestic arrangements stem from that age old fear - the dread of suppression by other, stronger and more populous peoples.

If you look closely at the picture above, you will see that the "ground" out of which the tortora reeds (which grow along the edges of the islands) appears to be covered with dead stems. That is because the "ground" out of which the reeds grow, and on which the huts are located, is actually not ground at all. It is simply mats of dried stems, tied together to make the floating islands. Where do they get the stems? From the weeds which grow on the edges of the islands.

These reeds are called "tortora reeds", and are almost waterproof, once they are dried. They have interweaving roots which create a dense layer up to two meters (a little over 6 feet) thick on top of which the islands themselves develop. Anchorage for the island is provided by driving large logs into the bottom of the lake. Ropes are then attached to these logs to give the islands stability. If there is ever a need to move the islands to a safer location, they simply release the ropes and float away.

however, the reeds slowly rot away and the islanders must replace them constantly. Each island will go through this process at least four times a year - more when the rains come. However, there is reward for all of this hard work as each island has a lifespan of around thirty years, and other than the hard work to keep them floating, the rent is free.

The tortora reeds themselves are malleable enough to dry out, bundle and shape in to extraordinary boats which float quite nicely.

With a leap of the imagination, the original Uros saw the possibility for a system of "boats" large enough to hold an entire village, and which, in case of emergency, could simply be moved away from the mainland. The also realized that the houses could also be made of the same reeds as the island on which they sit.


The reed islands are meticulously created by hand and are a continually evolving habitat for the Uros. Although the reed used for the island is not as painstakingly ‘woven' as that used for their boats, the construction of the islands represents an enormous workload for the people of the tribe. The islands themselves must be several meters thick in order to support the homes and associated buildings.


Although the Uros people number in the low thousands, it is thought that only about five hundred of them still choose to live in this ancient manner - though with some concessions to the modern world!

Traditionally there are around forty small islands on the lake with one - the largest - being the focal point of the community.

The reed, as well as being - quite literally - the foundation of the community, is important to the Uros' economy and well being. Iodine is produced from the base of the reed and it is also used for general medicinal purposes. The reeds are wrapped around parts of the body that are hurting and, purportedly - cure it of its aches and pains! The flower of the reed is also used to brew up a very tasty drink!

Like many unique cultures around the world, that of the Uros is under threat from assimilation. Most of the Uros speak Aymara - a highly regular language, which is also the language of a larger local tribe that remains resolutely mainland. It is thought that the Uros lost their own language around five hundred years ago. Whether the language was naturally lost or Aymara was forced upon them is not known, but the relatively recent arrival of Europeans has been the greatest threat to their cultural identity - greater than that of the Inca Empire - to which the Uros had to pay taxes and give up many of their own people as slaves. Many think that it was to escape from the Inca empire's people that the Uros first began to live on and escape using their floating islands.
