A number of specialist farms (birds, frogs, fish, vegetables, goats … ), mostly in the Lim Chu Kang Road area (away from the city) are open to the public at specific times on specific days.
Tour farms and buy farm-fresh local produce.

Each farm has its own opening hours. Non-drivers can get to the farms on the Kranji Countryside Express.
For group tours covering multiple farms, Mr. William Ho, KCA’s resident licensed tour guide is a great help. Contact him @ unclewilliam@unclewilliam.net.
