Singapore - Best parks to visit in Singapore?

I am thinking of visiting a few green parks while in Singapore in April. Such as Southern Ridges Walk, Fort Canning Park, Bukit Timah Reserve, Sungei Buloh Wetlands, Macritchie Park, Labrador Park, Orchid Gardens, Botanical Garden...

Which of the above do you think is well worth a visit?

I have 4 days only in Singapore, and I have never done any of the above before.

I would especially like to visit Fort Canning, so I guess that one is definitely going to happen.

Botanic Gardens is really nice and there is a new MRT station near it.

Fort Canning Park has a lot of history and it is right in downtown Singapore.
Very easy to walk around.

I would recommend these two.

I second the vote for the Botanic Gardens and Sungei Buloh. Add to that your decision for Fort Canning. These 3 together will give you a very nice slice of Singapore.

Botanic Gardens - As much about history as anything else. The canonball tree, the rubber saplings ...
Sungei Buloh - Mangrove and wetlands, fast disappearing all over South East Asia
Fort Canning - Early colonial history, cemetery

Bukit Timah and Macritchie maybe fairly similar experiences. I think they technically touch each other and you can hike from one to the other if you have a good map. Labrador I would pass but that's just me.

Another idea if you get a chance is perhaps Pulau Ubin (Ubin island) as that is quite a "park" too.

+1 for Pulau Ubin. One of the few places in Singapore that don't feel at all like Singapore -- and you can tick mangroves off your list while you're at it, as there's quite a nice trail & boardwalk at Chek Jawa on the east side of the island.

The Orchid Gardens were spectacular. And the park also has a lot of activities as well. Say a dog club when I was there.

i've been transiting a few times through Singapore and during my last stop i enjoyed a lot the Southern Ridges Walk.
Botanic Garden is also a must see

The good thing about Fort Canning is that it gives you some nice views once you reach the top, and you can then climb down the other side and end up right at B.B.'s bar at Clarke Quay for a quick pit-stop. :)
