Kallang Park Connector
The first part of this hike is on the Kallang Park Connector along the Kallang River. To get to the park connector from the Potong Pasir MRT station, it is a short walk in a residential area with somewhat triangular HDB flats and then across a bridge. At this stage, the Kallang river is like most Singaporean rivers i.e. with concrete banks, so not great. But the park connector alongside is free from traffic and crossings which is pleasant.
As usual for Singapore, we saw a crew of otters swimming downstream in the river. There is a section of the river where they tried to make it more natural by adding rocks and plants, which was a nice break from the straight concrete basin. After about 4 kilometres and crossing three major roads by pedestrian bridges, you reach Bishan-Ang Mo Kio Park.
Bring a Sun Hat
Besides sunscreen, you can protect your face against the harsh sun with a sun hat. We always throw hats in our backpack, and use them regularly. They are not very useful in the jungle, but once you get to the open sections you are happy to carry one along. I’ve got this airy sun hat from a great American outdoor brand called Outdoor Research:
Outdoor Research Swift Sun Hat on Amazon*.
You may prefer something with a wider brim, like:

Bishan-Ang Mo Kio Park
The nicest part of the Kallang river flows through Bishan-Ang Mo Kio Park. They have really tried to restore the river to its natural way of flowing, meandering through the park with lots of reeds. There are also some exciting stepping stones across the river, so you can check out the river life up close. There are plenty of fish, explaining the otters. Apparently there are also stingrays in the river according to the many warning signs.
It is quite a large park, stretching for about 4 km along the river all the way to Lower Peirce Reservoir Park. It is definitely one of the nicest city parks in Singapore. A major road crosses the park and for the moment you need to cross it with traffic lights, but work is on the way to create a tunnel.
Lower Peirce Reservoir Park
Crossing Upper Thomson Road at the far west of Bishan-Ang Mo Kio Park gets you to the entrance road to Lower Peirce Reservoir Park. After a short walk along the quiet road, you enter the park on the left and not much further is the Lower Peirce Reservoir. This reservoir is rather scenic, and you can enjoy the views while walking to the far end of the park where the Kallang river originates.
We had a snack break on one of the many benches along the way, and afterwards went to the boardwalk. The boardwalk takes you along the edge of the reservoir for a bit, before venturing into the forest. We headed to the Casuarina entrance. From there it is a short walk to one of the entrances to Thomson Nature Park.
Thomson Nature Park
This is a very interesting nature park. Initially, the only thing you meet is jungle. But after a while, there are numerous ruins along the way. There used to be a Hainan Village here until 1975, but the jungle is quite rapidly taking back control. The park is meant as a buffer park to protect the Central Catchment area in the centre of Singapore.
There are quite a few trails to explore, leading to different ruins. Although these ruins aren’t ancient or even old, it is slightly weird that they are there and the jungle is taking over again. We ended up at the official entrance of the park, where there are some information signs and a toilet building.
After a final loop from the entrance to more ruins, we headed out to the road. We then took a bus back home from Upper Thomson Road, which passes the entrance of Thomson Nature Park.
