This tour involves walking over some cobbled and uneven ground, including steps. The tram may be subject to some delays due to local traffic or obstruction. It is important to note that the trams have their original engine, which adds to the charm, and they will generate some noise. Guests are advised there are some fairly high steps to be negotiated when boarding the tram. The street leading to and from the Ribeira Quarter is on an incline and cobbled. Flat, comfortable shoes are recommended.
