AUTHORITIES have warned that they will crack down on cyclists at popular High Island Reservoir in Sai Kung. Country park officials said police had been told not to tolerate cyclists caught on restricted roads in Sai Kung East Country Park and along the reservoir. These include Sai Kung Man Yee Road and Sai Kung Sai Wan Road, and a trail between Hoi Ha and the Wan Tsai Peninsula. The area is popular with weekend cyclists, who ride the winding roads surrounding the reservoir and lead to quiet beaches. An Agriculture and Fisheries Department spokesman said: 'In co-operation with the police, we have stepped up enforcement. 'Verbal warnings will usually be given but a summons may also be issued,' the spokesman said. He said authorities had turned a blind eye to the practice for years, but would not say what had prompted the sudden enforcement. Currently, cyclists are allowed on trails in only four country parks - Sai Kung West, Shek O, Pui O and Lantau South - and on nine other free-access roads. But cycling enthusiasts have cried foul, arguing the restriction at High Island has not been enforced for years. Hong Kong Mountain Bike Association chairman and police inspector Richard Barton-Smith said there was no reason not to open the area to cyclists. 'It's an extremely popular and excellent road for cyclists and it poses no problem for other people. 'I have no idea why they choose to enforce the law now when for the five to six years I have been cycling in the area, I have had no problem from the police there,' he said. The department spokesman said there was no plan to make the road legal for cyclists. The Transport Department recorded 11 deaths and 829 injuries involving bicycles last year, but had no breakdown on where the accidents occurred.
