Kallang River is the longest river in Singapore and is appx 15km long.
It originates from Lower Pierce Reservoir and ends at Kallang Basin where National Stadium is located.
Earlier today, I took the opportunity to bike from Lower Pierce Reservoir Car Park to National Stadium via the Kallang River PCN which took me appx 2 hours.
Glad to report that biking and walking along the PCN is very doable even though there is need to use the overhead bridges that span across the Braddell Highway & Nicoll Highway.
The paths are generally well marked and do be careful when crossing the massive multi-highways at the Serangoon Road / Upper Serangoon Road / Macpherson Road / Bendeemer Road junction.

The key Landmarks along the Kallang River PCN

The Lower Pierce Reservoir Car Park is a great meeting and start point. There is ample car park space and the location is serene and beautiful. It is appx 500m away north of the entrance to the Bishan – Ang Mo Kio Park.

The Upper Thomson Road entrance to the Bishan – Ang Mo Kio Park is near the junction of Ang Mo Kio Ave 1 and Upper Thomson Road. This park is very well landscaped and the Kallang River runs parallel to the park.

The Eunoia Junior College has a commanding view of the Bishan – Ang Mo Kio Park and the Kallang River. It is located near the junction of Sin Ming Ave and Marymount Road.

SBS Transit has their massive bus terminal at the junction of Braddell Road and Kallang River. The PCN runs opposite the SBS Transit Terminal.

The St Andrews Campus which houses the Primary, Secondary and Junior College is unique as it operates on both sides of the Kallang River and there is a bridge which connects the Campus. The Rugby Fields are prominent on both sides of the river.

The National Stadium is the Go-To Place for all major sporting and entertainment events in Singapore. It is located at the mouth of the Kallang Basin where the Geylang River meets the Kallang River before flowing into the Marina Bay.
