Hey Melbourne, there's a new boat in town! Port Phillip Ferry has just started running from Wyndham Harbour to Docklands with their impressive 400 seat catamaran. The ferry has been started to service commuters wanting to avoid the highway and cramped trains but it also makes for a fun little adventure for families.
The trip goes for 1 hour and 15 minutes and you get the choice of comfortable indoor seating or braving the elements on the outdoor deck (way more fun!). There are toilets on board and space to park the pram. The lower level is fully accessible but there are only stairs to the upper deck.
Starting the trip at Wyndham Harbour will get real straight away as you hit the open water. The ferry goes quite fast and the day we went for a ride the water was fairly rough. If the kids don't like the motion try and sit on the lower level where it is a smoother trip. Things slow down considerably as you near Williamstown and there is a casual pace perfect for sightseeing all the way to Docklands. Along the way you will see the Sea Shepherd, Scienceworks, the Westgate Bridge, the Port, plenty of container ship action, the Bolte Bridge, great skyline views, the Melbourne Star and Docklands.
There are several trips each day so you do get the choice of how much time you spend in Docklands before returning. (Timetable here). Some attractions that are close by are Library at the Dock (and it's great little playground), The Cow in the Tree, HarbourTown, Etihad Stadium, Harmony Park and there is also a tram stop close by that is within the free tram zone that will get you to plenty of places in the CBD.
As an introductory special the Ferry is offering adult return fares for $20 until June 30th 2016 and children are $15. Kids under 3 are free. Tickets are purchased on board, cards welcome. For more pricing details check the website.
