Trail maps are on sale at the Government Publications Centre, and some are available at HKTA Information and Gift Centres. The Kadoorie Agricultural Aid Association has sponsored much research, in association with the University of Hong Kong, since the 1950s. The Kadoorie Experimental Farm, on a hillside near Tai Po, is a New Territories sightseeing attraction. To avoid disruption of its work, and to ensure the safety of visitors on its steep stepways, the Farm limits the number of visitors admitted each day. Local travel agents can arrange group visits with advance notice.
Admission is free.
The Farm has an information centre and interested groups are welcome. Of special interest is the nesting site of the Luk Keng Egretry, and the major transit site of migratory birds in the Mai Po Marshes. Access to the egretry is strictly controlled during the nesting season, and visitors always need a permit to visit the protected area of Mai Po. Bird-watchers and ornithologists can make advance arrangements to visit by calling the World Wide Fund for Nature on 2526 1011. The Hong Kong branch of the World Wide Fund for Nature manages the marshes, which contain a new breeding ground.
