Lake Titicaca is one of the many amazing places on this planet and at 3800 metres is generally regarded as the highest navigable lake. We were there, unfortunately many years ago, and we were lucky to have this wonderful day with the blue sky, the blue water and the white clouds. It was very warm to start with when we took our tour of the lake from Puno but at that height the temperature quickly fell as the sun became lower in the sky. We were fortunate unlike many others who had warmer clothing with us as it was an open boat. A fantastic experience if you manage to get there.
