Went to the specialised markets area of Mong Kok which is a short MTR ride from hotel.
Plants, flowers, birds, goldfish, fish and meat and of course the tacky street markets. Spent a couple of hours walking around and then caught MTR to Hong Kong Island to catch the cable tram to the Peak, a hill behind this part of the city. Great views over the city and harbour. Shattered walking for two days.
