Lorong Halus Wetland is one of the most unusual walks connected to Punggol because the landscape is doing several jobs at once. It is a wetland, a water-treatment system, a birding area, a park-connector crossing between Punggol and Pasir Ris, and part of the old Lorong Halus landfill story. The bright red bridge across Serangoon Reservoir makes it visually memorable, but the wetland is more interesting once you understand what the reeds and treatment cells are actually doing.
Important 2026 access note: NParks currently lists a partial closure of Lorong Halus Park Connector from 23 November 2024 to 31 December 2026 for MRT works. Visitors should follow current on-site diversion signs rather than relying on an old cycling or walking map. This guide explains the walk as it exists in that temporary construction context.
Lorong Halus is physically across Serangoon Reservoir from Punggol, but it belongs to Punggol’s real environmental system. The east entrance of Coney Island sits near the wetland, the red bridge links the Punggol side to the Lorong Halus/Pasir Ris side, and the wetland helps protect the reservoir’s water quality.

The red bridge route from Punggol
The simplest Punggol-side approach is from the Punggol East / Riviera / Coney Island side. The exact route can shift during construction, so use a live map and follow NParks/LTA diversion signs.
A typical walk links:
- Punggol East / Punggol Promenade Riverside Walk;
- Serangoon Reservoir edge;
- red Lorong Halus bridge;
- wetland treatment cells and birding areas;
- the wider Lorong Halus Park Connector toward Pasir Ris.
If you enter Coney Island from its east gate, Lorong Halus becomes part of a longer nature/cycling route rather than a standalone visit.
What the wetland is actually for
Lorong Halus was historically used for waste-related functions including landfill activity. When Sungei Serangoon was dammed to create Serangoon Reservoir, the site needed environmental treatment so contaminated groundwater and leachate would not simply enter the reservoir.
The wetland system uses engineered treatment cells and vegetation to help treat water before discharge. This is why Lorong Halus is a particularly useful place for students: the “nature area” is also environmental infrastructure.

The birding layer
NParks specifically identifies Lorong Halus Wetlands as a birdwatching stop. The park-connector description mentions species including Chestnut Munias and Little Grebes, while the reservoir, reed beds and open landscape can also support other resident and migratory birds.
Birding is best approached quietly:
- walk slowly;
- use binoculars if available;
- stay on paths;
- avoid loud playback calls;
- do not enter reed beds;
- do not feed birds.
Best time to visit
Early morning and late afternoon are usually more comfortable than midday because the site is exposed and shade can be limited.
- Morning: cooler walking, active birds, softer light.
- Late afternoon: good light over the reservoir and red bridge.
- Midday: hotter and more exposed.
- After rain: surfaces may be wet or muddy around natural edges.
What to bring
- water;
- sun protection;
- insect repellent;
- walking shoes;
- binoculars / camera if birding;
- rain protection;
- charged phone with live map.
Walking with children
Lorong Halus can be an excellent real-world Science/Geography walk for older Primary children and teenagers because the site connects water treatment, wetlands, land-use history, reservoirs and biodiversity.
For young children, the long exposed route can be tiring. Keep the walk short, use the red bridge as the main objective and avoid turning the outing into a forced environmental lesson.
Cycling
The Lorong Halus Park Connector is part of the North Eastern Riverine Loop and wider Round Island Route. It is therefore a major cycling link between Punggol, Pasir Ris and the eastern coastal network.
But the current partial closure matters. Cyclists must follow detours and slow down around construction interfaces and mixed pedestrian areas.
Wheelchair / stroller accessibility
NParks lists Lorong Halus Park Connector as wheelchair-friendly, but temporary works can change the smoothness or directness of the route. Families with wheelchairs or strollers should check the current diversion and weather before making the wetland a long outing.
The Coney Island connection
Coney Island’s East Entrance is near Lorong Halus Wetland. A longer route can combine the island and wetland, but remember that Coney Island is open 7am–7pm and closes at night.
Fishing?
Do not assume every reservoir edge is a legal fishing point. Fishing is allowed only in designated areas under current NParks/PUB rules. Use the official fishing-area information rather than choosing a quiet bank because it “looks fishable”.

Photography
The red bridge is the obvious photo subject, but the better images often include:
- reed beds;
- reflections on Serangoon Reservoir;
- birds using the wetland edge;
- industrial/environmental contrast;
- cyclists crossing between urban Punggol and the rustic Lorong Halus side.
Why the construction closure should not be hidden
A current walking guide that does not mention the 2024–2026 partial Park Connector closure can send visitors directly into a detour. Local guide quality depends on operational truth, not timeless prose.
The route should be refreshed after 31 December 2026 when the current closure period is expected to end, subject to any extension or new notice.

Lorong Halus is not simply a pretty red bridge. It is where Punggol’s reservoir, old landfill history, water treatment, birdlife and regional park-connector network meet. Walk slowly enough to see the system.
