This was the only walking tour I could find of central Lima - and I'm so glad we booked it. We were the only two attendees, and during our 'private' tour, our guide spent more than three hours giving us an overview of Lima's colonial and post-colonial history, the significance of the religious and cultural sites in the centre, and Lima's current realities. We looked into local restaurants and shops and the central market in addition to well-known sites like the San Fransico Monestary, venturing off the typical 'tourist track.' We left the tour much more knowledgeable about the city's colorful history, and well-equipped for doing further wandering on our own. Highly recommended.
