Whoever read Indonesian local newspaper during year 2012 must’ve known this place. Yup, Waduk Pluit city park is a famous park built during Jokowi’s first year as Jakarta governor. This park is located on the west side of Pluit reservoir, and extended along Ali Sadikin street to the south side of the reservoir.
When I visited the park at around 4pm, the weather is just nice. There you could see people doing group games, basketball, kite flying, jogging, cycling, family walks, hang outs, not to mention lots of couple dating.
A police office and police kiosks are located just nearby, making Waduk Pluit city park is a safe place for tourists. I find this place is good to sit back and relax, although most of the time sitting on the ground since benches are occupied most of the time.
If you are visiting the park with a car or bike, the park has a parking lot with plenty of slots. And if you want to use public transport, you could take Transjakarta Corridor #9 (take a single, non-articulated bus) or #12, and get off at the last stop, Pluit shelter. Then Waduk Pluit city park can be accessed from 5 minutes walk to the east.

Outdoor stage in the middle of the park. 
Can’t find empty benches to sit? The outdoor stage area has plenty of room for you to sit, even to take a nap! 
Open spaces on the lake side. 
Waduk Pluit is a nice place to relax for humans, and cats. He seems unhappy being photographed though ? 
Pavements. It’s shoes and bicycle friendly.

Some remaining debris… 
Lakeview from the park is definitely not the best view as the east side of the lake is still full of slums. 
Ali Sadikin Street. Reservoir on the right side. Extension park on the left side. 
More open spaces alongside Ali Sadikin Street. There are no recreational facilities built here, just trees.
