Kembla Trails and the Illawarra: What's Open, What's Closing
The Illawarra Escarpment has carried unsanctioned singletrack for decades — tight, punchy trails cut by riders who knew the mountain was capable of more than it was officially allowed to offer. In September 2025,
There's a second story running alongside the opening. From June 2026, NSW National Parks and Wildlife Service began closing and rehabilitating around 12 kilometres of unauthorised trails in the Mt Keira section of the escarpment. By 2028, those unformed, environmentally costly lines will be absorbed back into the bushland. The approved network is what replaces them — and with Stage 2 (Kembla and Balgownie, another ~50 km) expected to open in 2027, the trade is looking increasingly favourable.
Quick picks
- Best green to start: Easy Rider (730 m) — connects cleanly back to the main carpark; bail-out point at any junction
- Best intermediate: Switched Up (2.0 km) — the longest single run in Stage 1, flowing spine that links to most other blues
- Best black descent: Do Drop In (1.1 km) — signature gravity drop from the upper escarpment
- Worth warming up for: Mad If You Don't (870 m) — technical black with tight lines and less forgiveness
- Drive time: 15 min from Wollongong CBD; ~90 min from Sydney; ~2.5 hr from Canberra
- Cost: Free. No lift pass, no shuttle booking, no day fees — you earn the views.
- Critical: There is no drinking water on site at either carpark. Bring everything.
What are the Kembla mountain bike trails?
Stage 1 of the Illawarra Escarpment Mountain Bike Network sits inside the Illawarra Escarpment State Conservation Area, roughly 10 km from Wollongong's CBD off Harry Graham Drive at Kembla Heights. The project is a joint delivery by NPWS and Wollongong City Council, with both organisations co-investing the
The trails sit on Dharawal Country, and Aboriginal stakeholders were part of the design process and ongoing advisory group from the start. That's not boilerplate — the Illawarra Escarpment has cultural significance well beyond mountain biking, and the project team was explicit about it. A number of the trail names carry that connection quietly.
The Wollongong Mountain Bike Club (WMBC) has been advocating for legal trails on the escarpment since the early 2000s, and probably longer informally. They're embedded in the ongoing management — running volunteer maintenance days with NPWS rangers and acting as the community face of the project. The trails you're riding are a direct result of their persistence.
What's the trail mix like?
Twenty-five named MTB runs across roughly 20 km, split between two carparks. The grade breakdown:
| Grade | Trails | Character |
|---|---|---|
| Green | 4 | Beginner loops from the main carpark; genuine easy-grade, not sanitised blues |
| Blue | 13 | Flowing intermediates, ridgeline spines, coastal views |
| Blue/Black | 1 | Bridging run between the intermediate and technical zones |
| Black | 7 | Technical descents, exposed rock features, sustained gradient |
For a newly-opened network, the progression is well considered. The green trails are honest — Easy Rider at 730 metres gives real terrain without punishing a learner, and it connects back to the main carpark at multiple points, so there's no committing to more than you're ready for. The blacks are honest in the other direction. Do Drop In drops 1.1 km on a coastal escarpment that doesn't apologise for its gradient; Mad If You Don't (870 m) has the kind of tight, technical character that teaches you quickly whether your skill level matches your confidence.
The standout intermediate is Switched Up at 2.0 km — the longest single run in Stage 1 and the blue that most riders will do first and most often. It's a flowing spine that naturally links to the surrounding blue network, and it gives you a feel for the mountain's rhythm: the escarpment's abrupt vertical meets a trail design that channels it into something rideable rather than survival-focused. Echo (1.56 km) and Endless Summer (1.46 km) run the ridgeline with views east over Wollongong and the Pacific. On a clear autumn morning, these are among the more photogenic trails in NSW.
There's no lift and no commercial shuttle. The network is designed as a self-powered experience — you ride up, you ride down. The elevation gain won't surprise anyone used to NSW trails, but the escarpment setting means the descents are sharper than the numbers suggest.
What's closing at Mt Keira, and why?
From June 2026, NPWS began closing and rehabilitating approximately 12 kilometres of unauthorised trails in the Mt Keira section of the Illawarra Escarpment State Conservation Area. The work runs in stages through to 2028.
The closed trails are being physically blocked with barriers and signposted. The reason is environmental: informal trails on a steep, forested escarpment erode soil, fragment native vegetation, and create persistent public safety risk. The Illawarra Escarpment Mountain Bike Strategy identified their rehabilitation as the necessary environmental counterpart to building the legal network. You don't get the 70 km approved system without decommissioning the informal one.
Penalties apply for riding closed trails. This is worth stating plainly: the Mt Keira closures are inside a state conservation area, they're clearly signed, and NPWS is actively managing the rehabilitation. The Kembla Stage 1 trails are open, free, and 10 minutes away. There's no reasonable case for riding the closed lines.
For riders who came up on Mt Keira's informal trails, the knowledge and love of that terrain is what drove the advocacy for this project in the first place. Stage 2 is where that energy goes next.
What does Stage 2 look like?
Construction on Stage 2 — covering the upper Kembla area and the Balgownie/Tarrawanna zone — is scheduled to commence in 2026, with opening targeted for 2027. The Stage 2 scope adds approximately 50 km to the network, bringing the total to around 70 km once the Balgownie trails (in the Tarrawanna area north of Wollongong) are included.
That puts the completed Illawarra Escarpment Mountain Bike Network in the same tier as Blue Derby and East Kowen by total trail length — not a lift-served bike park, but a serious trail destination with genuine stature. Wollongong is a UCI Bike City; these trails are free and within 90 minutes of four million people. The case for the completed network as one of the more important new builds in the country is solid.
Stage 2 timelines are subject to final approvals. Track progress on the NPWS project page — it's been the most reliable source through the life of this project.
Getting there and what's on the ground
Two carparks, both free:
- Main Trail carpark (off Harry Graham Drive, near the Wollongong Motorcycle Track): serves the beginner green trails primarily. This is where to start if you're new to the network.
- Lower Kembla Heights carpark (near the Mount Kembla Bowling Club): serves the blue and black trails. There's an 800 m walk from the carpark to the trail entrance, which is worth knowing if you're loading up with gear.
Harry Graham Drive access: The road has been partially closed for upgrades for an extended period. As of late 2026, access to the main carpark runs via Mount Keira Road; the lower carpark at Kembla Heights is unaffected. Confirm current access via the NPWS local-alerts page before you drive in — roadworks timelines have shifted before and may still apply.
No drinking water on site. NPWS, WMBC, and Visit Wollongong all say this, and they mean it. Both carparks have pit toilets and bike cleaning/wash stations (the biosecurity signage asks you to clean on the way out — do it; it matters for soil-borne pathogen management). Mount Kembla Village, about 5 minutes away, has a pub and cafés that do post-ride duties well.
No bike hire on site, no food, no commercial shuttle. The nearest hire is in Wollongong CBD. If you're visiting from outside the Illawarra, plan your logistics before arrival — this is a national parks trail network, not a resort.
Getting there from Sydney: The fastest route is M1/F6 south to Wollongong, then local roads to Kembla Heights. About 90 minutes from the CBD with moderate traffic; allow more on weekends. You can also come in via the Grand Pacific Drive if you want a coastal warm-up to the riding.
When is the best time to ride?
The Illawarra's coastal escarpment climate is milder than the alpine parks — rideable year-round, with conditions most reliable April through October. Spring and autumn are the sweet spot: the dirt holds moisture without turning greasy, the days run long enough for full laps of the upper network, and the coastal bush looks its best in September and April.
Closures happen after heavy rain (protecting the new surface), on Total Fire Ban days, and on high-wind days (escarpment tree-fall risk). NPWS posts current status via local alerts; Trailforks picks up trail conditions and closures from the community. Check both before a drive from Sydney.
Summer is rideable if you start early — by 7am on a clear January morning before the heat builds, the escarpment is genuinely beautiful. Don't be mid-mountain at midday in February without water.
Weekends fill the carparks from mid-morning. Both carparks are free and unmetered, but there's a fixed number of spaces and no overflow. Saturday 9am in spring — there will be motorbike club activity at the adjacent track and a full MTB crowd. Earlier is better.
FAQ
How many trails does Kembla have, and what's the total distance? Stage 1 has 25 named MTB trails covering approximately 20 km in the Illawarra Escarpment State Conservation Area. The network also includes connector and management tracks bringing the total mapped routes to around 28. Stage 2 will add roughly 50 km, with the full network targeting around 70 km by 2027.
Are the Kembla mountain bike trails free? Yes. Entry is free and no booking is required. No lifts, no commercial shuttles, no day passes — NPWS built this as an open access national parks trail network. Your only cost is getting there.
What is the Mt Keira trail closure? NPWS is closing and rehabilitating approximately 12 km of unauthorised (informal) trails in the Mt Keira section of the Illawarra Escarpment State Conservation Area. Closures began in June 2026 and continue in stages until 2028. Trails are physically blocked with barriers and signposted. Penalties apply for riding closed trails. The NPWS rehabilitation page has the current status.
Is Kembla suitable for beginners? Yes. The four green trails connect cleanly to the main carpark at multiple points, and Easy Rider delivers a genuine beginner experience rather than the watered-down blue some parks mislabel as green. Bring a companion if you're new to the area — the escarpment terrain looks steep from the road and the trails deliver on that promise at the harder grades.
Do I need to bring water? Yes, and more than you think. There is no drinking water at either carpark or anywhere on the trail network. The escarpment gets warm in summer and the climbs are real. A 2-litre minimum on a summer lap; carry more if you're doing multiple runs.
When does Stage 2 open? Construction is scheduled to begin in 2026, with the target opening for Stage 2 (Kembla) and the Balgownie trails in 2027. The full network will be approximately 70 km once complete. Track current progress on the NPWS project page — construction timelines are subject to approvals.
The Kembla mountain bike trails are already the best thing within reach of Wollongong's 300,000 residents. When Stage 2 fills in the upper escarpment and the Balgownie north zone, this becomes a genuine overnight-trip destination for Sydney and Canberra riders on its own merits. Get there for Stage 1 while the trails are still relatively quiet.
For the full NSW picture, the state trails page covers every network. The Mogo Trails review is worth reading if you're combining a Kembla trip with a push further down the South Coast.
