When it comes to places to visit and places for day outings, all places aren't open. All museums and other places of interest that operate under the Leisure and Cultural Services Department have been closed down. Theme parks like Ocean Park Hong Kong, Hong Kong Disneyland are still open. Also, major sites like the Ngong Ping 360 cable car, The Peak Tram, The Observation Wheel, sky100 Hong Kong Observation Deck and Monopoly Dream Hong Kong are open to visitors. But you will need to follow the safety protocols that the properties have come up with. The best option would be to go through the official websites for more information on their precautionary measures.
