In these days of political correctness, visiting six pubs in one go is probably frowned apon, but it makes a nice trip out.  Travel to Warwick by train is easy, so no need for cars.   The route is shown in yellow on the map. You can download a higher resolution copy of it.  Do it with the usual right click and select "Save target as" menu selection The journey starts at Warwick station.  From there walk North West until you reach the Grand Union Canal and then walk next to the towpath heading West and step through a hole in the hedge to get onto the towpath.  You will soon see the Cape of Good Hope which you get to by crossing over the locks.  Most people manage to do this without falling into the canal!

Here are pictures of the pubs on the route and a little text shamelessly plagiarised from the Warwickshire CAMRA website and their copyright is acknowledged.

TheCape of Good Hope The Cape of Good Hope is adjacent to Cape top lock on the canal. Built just after the canal opened in 1800, it has given its name to the canal locks, the street and the surrounding district. A painting in the rear lounge explains the story of its name. It has a traditional bar at the front, and an enlarged lounge at the rear. Two LLocks is a house beer, previously brewed by Walsh's Bakehouse Brewery in Warwick. The brewery was also located by the canal, below the two Cape locks - hence the name. One delivery of beer in 2004 was carried by boat between the brewery and the pub.  An excellent pub which is far better than its website
The Kings Head The King's Head is a two roomedsymetrical Georgian pub. Extensivly redecorated November 1998 - the two rooms are now the Music Room and the Tapestry Room. Just before reaching this pub you will have noticed the unusual building on the North side of Saltisford Road with two octagonal towers.  This was the original Warwick gas works which is being converted into flats.
The Old Fourpenny Shop Hotel. The Fourpenny Shop A Popular pub for its varied range of real ales. Most guest beers last only a day!It was a racing inn and stables for the near-by racecourse. When the street was constructed in around 1800, the fine Geogian building we know today was built. It was offically named The Warwick Tavern. However, around this time the Warwick and Birmingham and the Warwick and Napton canals were under construction. The pub became a favourite for the navvies because it sold coffee with a tot of rum for 4d (4 old pence), this was 2d cheaper than other local pubs. Hence the nickname, which over 150 years later became adopted as the offical name. The suffix Hotel was added in 1987 when the owners opened the guest rooms.
