Hong Kong is a city known for crowded housing, skyscrapers, and just all around big city life. And it's true that the city is packed with people. The Kowloon area in particular doesn't have many breaks between buildings that aren't streets. But downtown Hong Kong is right up against a mountain, so it doesn't take long before someone headed away from the water starts going uphill.
I spent around an hour here, but even then I don't feel like I got a good idea of all it has to offer. It's a peaceful, adult-centered park, There is a children's playground, too. I'll definitely have to go back to the park again if and when I am able to return to Hong Kong.
The park itself is open 6:00-23:00, with facilities having shorter hours. The conservatory and aviary are open 9:00-17:00, while the restaurant is open 11:00-22:30. You can visit the park's website here.
