Razor Hill divides Tseung Kwan O and Sai Kung's countryside, rising over 430m. After a tough steep but luckily short climb from Pik Uk, I arrived at the top where the drone didn't need to go that high up to enjoy panoramic views of both city and nature.
Beyond the hills is the main city skyline.
The area around the Pik Uk jail is mostly lowrise and serene. I had started the hike through these residential streets.
To the east, the Hong Kong University of Science and Technology has wonderful sea views.
To the north is Hebe Haven and plenty of countryside.
To the south is the bustling suburb of Tseung Kwan O.
