One of Singapore’s oldest geological formations, the Gombak Norite, is named for the hill (Bukit Gombak) because this rock formation occurs most prominently here. Norite are iron and magnesium rich rocks formed from the cooling of magma deep in the Earth’s crust.
In the Bukit Gombok area lies the former Seng Chew Granite Quarry, sitting on a small hill about 500m north of Little Guilin. After its abandonment, rainwater filled it up and the former quarry became a lake.
The development of Bukit Batok Town Park saw one side of the once-heavily forested hill trimmed to become the contoured slopes today. A drainage system is also built to allow excessive water from Seng Chew Quarry, especially during the thunderstorms, to flow down along the slopes to the underground canals.
Seng Chew Quarry had existed from 1949 to 1960. The period between the fifties and seventies was indeed the golden era for local granite quarrying industry.
After alighting at Bukit Gombak MRT station, we exited in the direction of Bukit Gombak Sports Hall and followed the park connector towards Block 383 Bt Batok West Ave 5. At the first block of HDB flats, we turned right and walked up the gentle green slope.
At the top, we walked along the longkang which carries water from the quarry lake. Soon after we followed the drain to go further into the forest. There is a fallen tree trunk lying across the path. We went under it and soon reached a fence. There is an opening on the left side of the fence for closer look at the quarry lake. It is a very short trail to this lake. When we returned to the top of the slope, we decided to walk along it to the other end. This slope is actually an ideal spot for a picnic. There are many residents taking a walk here or doing yoga exercises.
We saw an opening into the forest and walked in. We saw a vegetable garden with many banana trees, chilli plants etc. Slightly ahead, we were rewarded with an aerial view of the quarry lake with an even better view. Although Seng Chew Quarry is not well known, it is surprisingly easy and convenient to reach it.
