From the Tin Hau MTR bus terminal take the 49M mini bus and get off on Braemar hill road by the St Joan of Arc secondary school. The trail will start from there.
Difficulty 7/10 and the accent of the mount Butler is a challenge. Uneven steep at times rocky trail and lots of stairs.
Approx 2.5 hrs to reach Shek O beach from getting off the 49M bus.
Well worth it when you reach the summit.
