The Kadoorie Farm and Botanical Garden is located in the valley along Lam Kam Road between Tai Po and Yuen Long and is most easily accessible by way of bus route 64K. Opening hours are 9.30am to 5pm daily and entry fees are HK$40 (adults) and HK$20 (children aged 5-11).
Note: The Kadoorie grounds are on the slope of a mountain. As such, you can purchase shuttle ticket (HK$10 per adult, HK$5 per child) and be driven to various drop off points from which you can walk back down to the entrance to the farm. Or take your time and walk upwards through the farm and garden grounds and take the shuttle back if you purchase ticket along with your entry fee.
This organisation is dedicated to nature conservation, rescue and rehabilitation of native animals, some of which are endangered or rarely seen and education about sustainable living. Particularly impressive are the efforts towards rescued animals. There are numerous facilities spread around the grounds, where you can view leopard cats, muntjac (barking) deer, bats, raptors, interesting reptiles and other animals in respectable enclosures. There is often information provided about the animals including names and ages if interested.
You will also find a lovely stream with surfaced walking paths and beautiful gardening and landscaping. This is a delightful area to walk and enjoy being in nature. Some benches and picnic spots can be found here and at other tranquil garden areas within Kadoorie as well.
There is an area dedicated to sustainable farming examples and education. You'll find a farm shop and cafe called the Sun Garden Cafe near the entrance. There are public toilets in various locations within the kadoorie grounds. Note, best to print or download the Kadoorie map and layout before setting off to explore as you will quickly learn how large of an area is included. It can be a bit tricky finding particular enclosures if you don't know your way around.
In the end, the location is a bit inconvenient of those in the city but the experience is rewarding for anyone who wants to spend 1/2 to 3/4 of a day in a valley countryside close to nature, especially a good option for those with children.
