All year round, fiercely proud 'Amsterdammers' over the age of 55 lead informal walks through the city on a route of their choosing. Tours last two to three hours and are an exceptional way of garnering information on the city, often first-hand as the guides share their own personal memories from living in the city. Starting point is Amsterdam Historic Museum's restaurant, David & Goliath, and tours must be reserved at least one day in advance by phone (Mon-Fri 1pm-4pm) or by booking online.
