Yes, you can find a winery tour operator that can take you and your friends to the Yarra Valley on the cheap with a half day tour. Now, keep this in mind as this is not a public bus tour, no winery bus tour will offer half day option.
At Kangaroo Hopping Tours, we do offer private half day wine tasting tour, and it is more expensive than the public bus tours. This is an option if you are looking for more private opportunity and you don’t have to pay for the whole day.
With a cheap half day winery tours, you choose only to pay for a designated driver for the small group. You will need to organise the itinerary with a list of wineries to visit of your choice. The time will allow you to visit 3 wineries close to each other to save time on travelling.
