Tours leave from near the old stock exchange building and head up through the city centre taking in most of the key sites.
The tour then continues down the Avenida Boavista and out towards the coast at Foz before returning back along the Douro.
There is then a short extension over the bridge to run along the riverside in Vila Nova de Gaia before returning to the starting point
A multi-lingual pre-recorded commentary runs for the whole of the trip
