Travelling from Peru to Bolivia presented us with one of the most picturesque border crossings on our round the world trip via Lake Titicaca, the highest navigable body of water in the world at just over 3,800 metres above sea level. Nestled high up in the Andes, many people believe this to be the birth place of the Incas, not hard to believe when you consider how tough Machu Pichu was to find. They sure do love secret hideaways, and this lake is in many ways just as mysterious as it’s more famous counterpart. On the Peruvian side you can find intriguing colonies of indigenous people living on man made reed islands, in Bolivia a rural island full of Inca ruins and agricultural communities that are yet to receive any form of transport or wifi. It’s a real back to basics trekking experience not to be missed if you’re feeling intrepid. We ventured forth to find out more.
