I have young kids, so we took them to Ocean Park and Disneyland.
Victoria Peak and the Tian Tan Buddha are common tourist spots.
There are different museums and gardens to check out. Boat rides and a light show in the harbor.
If you want to do some souvenir shopping, there’s the Ladies Market, Temple Street Market, Stanley Market, and more.
If you’re a member, I highly recommend going to the Hong Kong temple.
Happy to discuss more if you’d like. My mom is from Hong Kong and my dad served his mission there, so I’ve gone there once per decade.
