These farms are located in the Lim Chu Kang area. In a land area just before the Sungei Buloh Wetland Reserve. I believe there are more than 10 farms in that vicinity, and most, if not all, welcome visitors, though some of them require an entrance fee. For most of those that do not require an entrance fee, visitors can choose to pay a minimal sum for a guided tour.
The distance between farms are pretty far, so driving is a necessity. However, I do believe that "tourists" can pay a small fee for a package, which charters a bus to drive you to 10 farms within that vicinity - with guided-tours included.
