If you’re looking for something other than the usual hiking trails, then you should get out there and spend an afternoon stream trekking in Hong Kong! “Stream trekking” might sound a bit daunting at first, but this is a relatively easy and convenient (if you’re living on the island) hike that starts in North Point and should only take you a couple of hours.
If you’re not quite up to speed on Hong Kong’s history, Kowloon Walled City was an extremely densely populated section of Kowloon that housed an interesting mix of residents. Prostitution, gambling, and drug use were very common in this area. The Walled City was predominately ungoverned by HK, instead it was controlled by the Triads for the last few decades before the HK government decided to begin evicting all residents in order to demolish the city.
