At the age of 52, I have just returned from a trip that felt like the biggest I have done for a very long time. I took myself from the Chilean Atacama across into Bolivia to trail across the desert and the salt flats up to the highest capital in the world, La Paz. From there I ‘turned left’ and headed for Lake Titicaca into Peru and the Sacred Valley of the Incas. Machu Picchu was a life goal. Unable to resist the relative proximity, I tacked on an 8-day cruise through the West, Central & Eastern islands of the Galapagos archipelago; stopping in Quito on the way.
