So, we arrived in Puno which was the place I have waited to visit when my grandad told me about Lake Titicaca. Lake Titicaca is the highest navigable lake in the world and the largest lake in South America. It is 3812 meters high up and 8272 km2. Outside Puno, people live on floating Islands made of straw. We think they were the most amazingly built floating Islands we have seen during our world around trip. See our pictures.
