Beacon Hill is probably only second in popularity as a climbing spot behind Tung Lung Chau thanks to the beautiful view you get of Kowloon. Also, the access and the routes at Beacon are comparatively easy, so it’s a good spot for starting outdoor climbers.
The hill is on the east side of Lion Rock Country Park. To get there, take a taxi from Shep Kip Mei station to the Water Supplies Department off Lung Yan Road. From there you can trek up the slope to Beacon Hill. This spot is pretty easy to get to – you might even be able to squeeze in a climb after work before the light fades.
