From Cusco we headed down to Lake Titicaca, the largest lake in South America. At over 12,000 feet in elevation the lake is considered the highest "navigable" lake in world. We crossed the border into Bolivia and took a ferry to Isla Del Sol. The Island was considered by the Inca to be the birthplace of their all important Sun God. We found this tranquil place to be defined by the incredible warmth of it's inhabitants (whose ancestors have been living on the Island for thousands of years), and it's breathtaking landscape. Charlie, Evan and I walked across the hilly island in three hours on foot - as there are no cars! Footpaths connect several small communities and numerous agriculture terraces.
