Peru and Bolivia are both lands of the epic and that which must be seen to be believed. This 25-day odyssey takes you to the world’s highest-navigable lake (Titicaca), the world’s largest tropical rainforest (the Amazon), the world’s highest administrative capital (La Paz) and the world’s largest salt flats (Uyuni). It also includes the chance to trek the Inca Trail before emerging above Machu Picchu, which isn’t actually a world-record holder but probably should be for ‘best ancient city in the clouds’. In between the gasps you can ramble through markets, sipping Pisco sours and munching ceviche with locals.
