An obligatory stop in Lima is part of most itineraries to Peru. In fact, I recommend that you spend a night on either end of your trip to Peru in Lima as flights in Peru are often delayed due to bad weather or can be overbooked. We spent 5 hours in Lima on our first night in Peru and another 5 hours in Lima on our last night in the country. We spent a final 4 hours in the city the next day prior to catching our flight. Here's what you should do with that time.
