I had prebooked four-day tickets for one of Lisbon’s hop-on, hop-off bus tours. The busses follow a fixed route with a number of predetermined stops where passengers can hop off, explore an area and then hop back on a follow-up bus.
There were several companies offering this service, and after careful consideration, I chose the Yellow Bus company, which offers two routes with a collective total of 25 stops.
Saturday was bus riding day. We would ride both routes, looking for neighborhoods we would explore over the following days. Riders are given earbuds, which we can plug in and get a narration about sights along the way delivered in a language of our choice. Not being fascinated by the names of the architects who designed various buildings, I found the audio somewhat boring.
