A hiker was seriously injured after falling about 100 metres down a slope while trekking on Castle Peak in Tuen Mun yesterday.
Chan Lai-kau, 43, joined a mountain climbing session organised by Long March Trekking and had hiked from Ching Shan Monastery along Lung Mun Road with 40 other people.
Mr Chan, who was walking at the back of the group, lost his footing and rolled down a mountain slope near Butterfly Bridge. The slope is 137 metres above ground.
He suffered head injuries and broken ribs, and was picked up by a Government Flying Service helicopter and later taken to the intensive care unit of Tuen Mun Hospital. Last night, he was in serious condition.
A veteran hiker who was trekking with him said: 'The track is very sandy and full of rocks. There is no grass or trees, so it is dangerous if you lose your balance because you won't find something to hold on to. The weather at the time was very windy and Mr Chan was in a little bit of a hurry. He lost his balance and rolled down the slope.'
The hiker said the area was unpopular with hikers because of the treacherous ground.
'The surface of the road looks solid but there are holes here and there. The road is full of sand and small rocks - it is very easy to slip,' he said.
He said people seldom went to Castle Peak for hiking but the good weather yesterday had attracted many climbers. 'There are two hiking teams this morning - that's quite unusual,' he said.
He advised inexperienced hikers to be patient when walking across treacherous surfaces. 'I have been hiking for many years and I still find the place dangerous,' the hiker said.
