It would be understandable to assume that after seeing Machu Picchu, one might as well fly home. But Peru has myriad fascinating and stunningly scenic attractions set in widely varying environments, ranging from high-altitude valleys sculpted by centuries-old terraces to unique floating islands in otherworldly Lake Titicaca. Although I’ve now had several sojourns to Peru, each of which lasting two weeks or more, I discover something new and wonderful on every visit.
