Published 24 October 2026 | Bukit Timah, Singapore. Did you know that a route beginning near King Albert Park is part of a much bigger plan to connect habitats between Bukit Timah Nature Reserve and the Southern Ridges? The Clementi Nature Corridor has a practical walking story for families and a more complex conservation story that will continue into 2027.
Imagine strolling beside the Bukit Timah First Diversion Canal on the Holland Green Linear Park link. The existing trail gives people a relatively gentle encounter with greenery near established roads and rail. Now zoom out: forests around Clementi, Toh Tuck and Maju form ecological stepping stones. Planning for new recreational trails is happening alongside the difficult question of how much woodland should be conserved when more homes are built.
Quick answer: NParks describes Clementi Nature Corridor as an ecological connection between Bukit Timah Nature Reserve and the Southern Ridges, with an approximately 18km planned recreational route network. Holland Green Linear Park and part of the Clementi Nature Trail are already publicly accessible. NParks’ July 2026 information reported through Lianhe Zaobao expected the Clementi Nature Trail to be fully open in the second half of 2026 and indicated progressive Old Jurong Line Nature Trail openings from the second half of 2027. These are forecasts to verify against subsequent opening notices, not proof that the entire 18km network is ready today. Separately, 2026 Maju Forest housing plans and public feedback prompted a review of proposed greenery retention.

Did you know? Five useful facts first
- Why it matters: The nature corridor helps maintain ecological movement between Bukit Timah Nature Reserve and the Southern Ridges.
- Planned network: Around 18km of recreational trails and connectors across the broader Clementi area, not 18km of uninterrupted path already open.
- Available now: Holland Green Linear Park runs along Bukit Timah First Diversion Canal, with a public Clementi Nature Trail link.
- 2027 prospect: Progressive Old Jurong Line Nature Trail openings have been discussed for the second half of 2027; exact access requires an NParks notice.
- Conservation question: Maju Forest development plans have been revised or reconsidered following feedback; initial cleared-versus-retained figures must not be mistaken for a final detailed outcome.

What is the Clementi Nature Corridor, and why does Bukit Timah matter?
Nature corridors are not ordinary parks with one gate and a fixed opening hour. They are networks that help wildlife move between forested places even where roads, homes and other urban uses divide the landscape.
NParks says Clementi Nature Corridor contains forested sites at Clementi, Toh Tuck and Maju together with the Rail Corridor. It is intended to provide ecological connectivity between Bukit Timah Nature Reserve and the Southern Ridges.
That makes Bukit Timah one of the anchors of the network. The forest around Bukit Timah Hill is a core habitat. Connections toward the west and south allow species more chances to move, feed, disperse and potentially maintain healthier populations.
The corridor also links the Bukit Batok Nature Corridor with the Labrador Nature Park Network. These connections are important even if someone cannot walk every metre as a public trail.
This is the first distinction readers need: an ecological corridor is not always an open recreational route. Wildlife habitat may be conserved specifically because people should not enter it.
NParks explains the ecological role in its nature corridors and nature ways guide.
What does the 18km network actually include?
The 18km figure comes from NParks’ 2021 plan for a new recreational trail network in the Clementi Nature Corridor. It includes two nature-trail concepts and park connectors linking the Rail Corridor, Ulu Pandan, Old Jurong Line and further destinations toward Jurong Lake Gardens.
The Old Jurong Line Nature Trail is planned around the former railway alignment; Jurong Town Hall Park Connector provides another piece of recreational connectivity. Clementi Nature Trail follows the Bukit Timah First Diversion Canal to connect green spaces toward Ulu Pandan.
Different portions may be on park connectors, normal paths or newly designed nature trails. Their surfaces, access rules and opening dates should be checked section by section.
An attractive 18km overview map should therefore be read as a network plan, not permission to hike along 18km of finished uninterrupted wilderness. Some alignments are indicative and some habitats must remain protected.
The original description appears in NParks’ nature corridor and Old Jurong Line trail announcement.
Where can you walk today near King Albert Park?
Holland Green Linear Park is the easiest place to understand this project on the ground. NParks identifies the linear park as a 2.32-hectare green corridor along the Bukit Timah First Diversion Canal.
NParks’ updated listing says the park links with the Rail Corridor and Clementi Nature Trail. It also lists access from King Albert Park MRT via the Rail Corridor, giving Bukit Timah residents a way to enjoy a green outing without necessarily driving.
The park is listed as open 24 hours and wheelchair accessible, although anyone travelling at night should verify lighting, local path conditions and any segment-specific guidance. The nearby Rail Corridor has its own night-use restrictions and is largely unlit.
A visitor should not automatically infer that every future trail junction shown on a concept map is open. Use the current NParks park map and on-site signage when deciding where to walk.
The existing Holland Green link is a good example of a small, practical section of the corridor that is already useful while later network plans continue to develop.
See NParks’ Holland Green Linear Park page for present-day visitor information.
What is changing in the 2026–2027 trail timetable?
A July 2026 Lianhe Zaobao report, quoting NParks, said the Clementi Nature Trail was expected to be fully opened in the second half of 2026. It also described progressive opening of the Old Jurong Line Nature Trail from the second half of 2027, beginning with a section beside Clementi Avenue 6.
This is more recent than earlier reports suggesting the Old Jurong Line trail could begin opening from the end of 2026. The chronology matters because public projects are often rescheduled as design, conservation and site works proceed.
As of 24 October 2026, a published intention to open a section later in the year is not itself an official notice that all remaining sections have opened. The latest NParks maps and announcements should be used to establish actual access.
It is also important not to swap the two names. Clementi Nature Trail and Old Jurong Line Nature Trail have different alignments and phased timelines within the same larger nature-corridor vision.
The public benefit comes when individual sections safely open, rather than when the whole 18km is discussed in a single planning headline.
For the July 2026 reporting on NParks’ revised indicative timeline, see Lianhe Zaobao’s Maju Forest and nature-trail update.
Why is the Old Jurong Line such an unusual nature trail?
The former Jurong Railway Line was built to move goods between the industrial Jurong area and the main railway network. Traces of track and railway bridges remain, making the future trail an opportunity to understand both industrial heritage and ecological change.
As rail traffic ceased, vegetation gradually regenerated along parts of the former alignment. This created a mixture of human-made structures and living habitat that is different from a park designed entirely from scratch.
URA explains that the proposed Old Jurong Line Nature Trail will follow the railway’s old alignment through parts of Clementi, with its first phase linked to Ulu Pandan Park Connector. The broader network is intended to connect back toward the Rail Corridor.
The project’s appeal is not merely a photo of rusting rails. It shows how land can move from industrial transport to ecological and recreational value over several decades.
Visitors should never enter an unannounced closed stretch simply because an old track appears in a public photograph or a map of a future trail. The lawful trail and the historic alignment are not automatically identical.
URA’s Transforming Play in the West explains the old railway and future recreational connection.
What happened at Maju Forest in July and August 2026?
Maju Forest near Sunset Way became a major planning discussion in 2026. On 10 July, HDB released proposals relating to housing development at a forested site around 23 hectares and an environmental impact assessment.
The initial proposal discussed clearing approximately 15 hectares while retaining about 8 hectares for habitat, including significant areas around a freshwater stream and the Old Jurong Railway Line. These were initial published planning values, not a guarantee that every boundary was final.
Environmental groups and residents raised concerns about habitat fragmentation, edge effects, biodiversity and whether sufficient forest would be conserved. These concerns matter because a narrow green strip can be less useful for some forest species than a wide, protected habitat.
On 14 August 2026, the Government said it would adjust the housing plans at Sunset Way and Gillman Barracks to retain more greenery after public feedback, with fewer homes as a consequence. The final area and detailed layout require subsequent official plans; do not keep repeating the July figures as final.
Readers do not have to pretend that housing and biodiversity are the same goal. They can recognise the need for homes while evaluating whether mitigation, connected forest cover and ecological safeguards are adequate.
See CNA’s 14 August 2026 report on changed conservation intentions.
Why does a corridor need more than a pretty walking path?
A nature corridor has to work for wildlife, not only people. Birds, small mammals, insects and reptiles move through habitats in different ways. A broad forest patch may provide shade and cover that a thin planted verge cannot.
Connectivity can also be disrupted by light, noise, roads and changes in temperature or moisture along forest edges. That is why ecological profiling and planning safeguards matter even when a proposed development includes attractive trees and landscaping.
NParks says connectivity routes are continuously identified as land use is planned. This is an important statement of method, not proof that every development automatically preserves all the movement routes species need.
The safeguarded nature-park area at Ulu Pandan is intended to act as a stepping-stone habitat between Clementi Forest and the Southern Ridges, while the Rail Corridor offers another line of ecological connection.
A good 2027 update should ask what habitat was actually preserved, what green links are connected and whether monitoring shows the intended environmental benefits. Renderings are helpful, but field observations and approved plans are more informative.
What is the difference between the Rail Corridor and the Clementi Nature Corridor?
The Rail Corridor follows the former main railway alignment and has its own established heritage nodes, paths and repair notices. It is one component of the broader ecological connectivity discussed in Clementi Nature Corridor planning.
Clementi Nature Corridor is an ecological network encompassing forested patches, proposed nature trails and park connectors. It does not replace the Rail Corridor’s identity or management rules.
The Bukit Timah–Rochor Green Corridor is a third, distinct project. Its first elevated section near Jalan Kampong Chantek has an estimated 2027 construction completion, but that is not the same as the Old Jurong Line trail opening.
Three similar names can create enormous confusion in search results. The correct comparison asks for the route, location, responsible agency and actual status of each specific section.
A map of the broader Bukit Timah region can show how these routes may eventually complement one another; it should not draw unbuilt links as if they were pedestrian shortcuts today.
Can families walk the corridor with children or older relatives?
The answer depends on the section. Holland Green Linear Park is an established park with an NParks accessibility listing. A future nature trail through sensitive forests may have a different surface, gradient and set of access rules.
For a first family outing, the safest approach is to choose an already opened, clearly mapped public section. Check whether it is sheltered, whether benches or toilets are available nearby, and how easily you can return to a bus or MRT station.
Young children often enjoy looking for butterflies, birds or interesting leaves. These activities are best done quietly from open paths without collecting plants or following wildlife into undergrowth.
For older visitors, an accessible short route can be more rewarding than trying to cover all the miles on a network overview. Confirm current path conditions and whether any construction has temporarily diverted the entrance.
During thunderstorms or very heavy rain, postpone the walk. A linear park beside a canal still requires weather awareness, and protected woodland should never be treated as an emergency shelter.
For a longer future outing, do not plan through a section described only as ‘from the second half of 2027’ until NParks confirms public access.
How can residents take part in the corridor’s ecological future?
NParks’ Friends of Clementi-Ulu Pandan Nature Corridor group was formed in 2021 to support ecological resilience and community engagement. Its October 2026 page describes efforts such as habitat enhancement, restoration and BioBlitz nature surveys.
Volunteer and educational activities can make conservation more tangible. A family that learns to recognise native trees or document birds can begin understanding why habitat connections matter.
However, community participation should follow official programmes and approved access. Sensitive forest areas are not automatically available for independent trail cutting, planting or organised activities just because volunteers are interested.
For those following Maju Forest proposals, official feedback exercises and published environmental reports are more meaningful than unsupported claims about fixed future clearance areas. Ask what is proposed, what is approved and what will be monitored.
The latest community page is Friends of Clementi-Ulu Pandan Nature Corridor, updated 8 October 2026.
What should happen next during 2027?
The practical 2027 milestones to watch are actual NParks notices confirming which Old Jurong Line Nature Trail sections are safe and open, current maps for the Clementi Nature Trail and updates to conservation and housing decisions around Maju Forest.
The second-half-2027 indication for the Old Jurong Line route is a reported target, not a completed project. A later date or revised phasing should be reported with the new source rather than concealed under an old article headline.
At the same time, existing links like Holland Green Linear Park can already serve residents, provided any local access notices are followed. There is no need to postpone every green outing until the full network is delivered.
The bigger ecological question will extend beyond 2027. How future housing is designed around retained woodland, streams and rail corridors can determine whether the area stays connected for wildlife as well as people.
Bukit Timah’s green story is therefore a balance: keep existing public paths useful, add new access carefully and protect the habitats that make those paths meaningful in the first place.
- Now: Walk open sections such as Holland Green Linear Park, following present-day maps.
- Late 2026: Look for confirmed Clementi Nature Trail opening notices rather than relying only on anticipated dates.
- Second half of 2027: Follow official announcements for the first Old Jurong Line Nature Trail sections.
- For conservation: Track the revised Maju Forest plan after 2026 public feedback.
- For safety: Use legal entrances, respect protected areas and avoid exposed routes during thunderstorms.
