Mount Victoria Heritage Trail starts (if you want) at the Embassy Theatre on Marjoribanks Street by the sign Modern Shoe and Bag Repair, Dry Cleaning, Key Cuitting. At this sign there is a display about the Heritage Trail, what its intent is, and what to visit. Here the scene is also set for you to outline your journey around the Wellington Suburb of Mount Victoria, in which you can take in historical sites, ranging from Churches, Houses, Statues, Tunnels (2) and olive trees. The Olive Trees once won an international award, for there oil, but now are mainly enjoyed by the birds, and are a reflection of the time that there was a strong Mediterranean influence in the suburb.
To me, if you are a purist you could stick to the Trail as outlined, or you could include other things, such as having a beer in The Welsh Dragon Bar, at 10 Cambridge Terrace, which was once a public toilet. If fact you could mix the trail up a bit and have a pub tour at the same time, by going to the Cambridge Hotel, and then Boneface Tavern on Pirie Street, or the Black Sparrow, for a cocktail. There are also things not mentioned, that are also worth a visit, such as the Wellington Fire Station (perhaps not quite Mt Vic).
I started from St Gerard's Church and Monastery and ended up at the Basin Reserve, but you could do it the other way, especially on a hot day, and venture to Oriental Parade and take a swim, or you could finish at the Embassy and go to a movie. The Trail enables various ways to pursue what is on offer, and to me this is what makes it enjoyable. Suit yourself.
