I read earlier about the gibbston valley wine trail and my husband and I would love to cycle it (or walk but would prefer cycling). We are having a hard time with the logistics, it seems you have to book a tour group in order to rent a bike near the wineries? Any advice? The problem is we would like transport so neither of us has to drive but we don't really want to be stuck with someone else's itinerary for us/some of the extras like a packed lunch or a bottle of water which just racks up the price. Thanks!
