Pittsburgh has three major parks in the city limits - Point State Park downtown, which is a small area that hosts events, Schenley Park which has plenty of hiking, biking, and fishing, and Frick Park which is massive and allows you to get lost in the forest in the middle of the city. It's a great way to get out of crowded areas without traveling.

I don't know about other cities, but the ones I've lived near were simply too irregularly shaped. NYC was able to be built like a grid, but a city like, say, Buffalo (go Bills!) is both too wibbly wobbly as well as too cold to envision a park being used as a centerpiece.

Chicago has a huge lakefront park as well as large parks throughout neighborhoods connected by grassy and tree-lined avenues. Not quite Central Park but a lot of great park space throughout for residents.

Didn't Los Angeles have central green space (not on the scale of central park in NYC, but large) that was gradually eaten away and paved over with time?

Kings park, Perth.

Bigger than central park and high up on the only hill for miles

Some cities did, like Vancouver. But others thought it too expensive to the taxpayers and are now kicking themselves decades later. Or the taxpayers didn't want to support it back then.

Detroit has Belle Isle which was designed by the same guy who did Central Park.

Louisville has Cherokee park that was designed by Olmsted, same dude as Central Park.

When I lived there I loved to go dirt trail running in the middle of the city.

Paris in France has a few parks and gardens. It’s weird to thing that the US invented the concept: https://www.evous.fr/Guide-des-plus-beaux-parcs-et-jardins-de-Paris,1176706.html

Forest Park, St Louis MO

New Orleans has City Park. Go check it out!

Hyde Park in Sydney

Because its really hard to do it retroactively. Not too many people cared about its aesthetic/health or public value when compared to the commercial real estate value

The English Garden in Munich comes close: A long park reaching almost into the very center of the city.

Vancouver - Stanley Park (downtown), Queen Elizabeth Park (geographic center), Central Park (Metrotown)... The lack of parks in US cities is a matter of poor planning.

@someguy3 Portland, Oregon has the largest urban park in the country, Forest Park, but it is forested an not a garden park. Also it is on the edge of the city instead of Central.

Jesus I had no idea

We have lots of large parks in my city. Not central park sized, but we are not an NYC sized city. It's basically a small city incorporated into the forest. Sometimes they try to capitalize some of it, but the voters reliably shut them down, we love our green spaces.
