Porters Pass Circuit (Including Colliers Causeway and Centennial Glen Pass)

Last updated: June 26, 2023

The Porters Pass circuit is an exciting bushwalk in the Blackheath area of the Blue Mountains involving waterfalls, valley views, creek crossings, rainforest gullies, and slot canyons.

This challenging hike combines four different walking trails and is among the best in the Greater Blue Mountains region. What’s great is that Porters Pass is far less-trafficked than, for example, the Grand Canyon Walk.

Keep reading and learn more about this amazing walk and its highlights, how to navigate the trail, and where best to park your car.

How to Get There

The Porters Pass Circuit has multiple entry points, but the best spot to start this adventure is at the end of Burton Road in Blackheath (see map location).

This spot is a short 3-minute drive from the Blackheath town centre, via Station Street, Wombat Street, Kanimbla Road, and Burton Road.

Note that this is a residential street, so please park on the side of the road without blocking any driveways.

Below is a map of the walk along the following highlights and sections:

  1. Lamberts Lookout
  2. Porters Pass Gully
  3. Colliers Causeway
  4. Centennial Grove Grotto Canyon
  5. Centennial Glen Pass
  6. Fort Rock
  7. Clifftop Walk

Porters Pass Track Notes

We classify the Porters Pass Circuit as a moderate to hard walking track. There are lots of steps and sections with rough surfaces to negotiate. Good hiking shoes are recommended, and a set of hiking poles might also be helpful.

The distance is approximately 5.5 km, and overall, the path is easy to follow. However, there are multiple intersections where things can get a bit confusing, so it’s recommended to familiarise yourself with the route. The map above and track notes below will hopefully help with that.

1. Lamberts Lookout

Once you’ve parked your car and put on your hiking boots, it’s time to start this Blue Mountains adventure. At the information board at the end of Burton Road, follow the walking path heading into the bush.

After about 600 metres, you will see a non-signposted path on your left, moments before a signpost that says “Porters Pass and Colliers Causeway”.

Views from the Lamberts Lookout

Follow that path on your left for a short detour to the Lamberts Lookout, a rocky outcrop from where you can enjoy fantastic views of a cliff wall and valley straight ahead.

Once you’ve finished admiring the views, retrace your steps to continue on the main trail towards Porters Pass and Colliers Causeway.

2. Porters Pass Gully

From this point, the trail goes downhill, with the scenery evolving from typical Blue Mountains bushland to a lush rainforest setting.

This is where the path for a short while follows the Porters Pass Gully, a creek that you’ll have to cross a few times.

The walking track also passes a small, unnamed waterfall with handrails on one side to help with crossing the gully creek safely.

3. Colliers Causeway

The Colliers Causeway is a beautiful section of the Porters Pass Circuit, where you’ll be hiking alongside the base of impressively high cliff walls.

The narrow path is a bit challenging along this stretch, but as long as you stay focused on your surroundings, it’s all very manageable.

Colliers Causeway

Towards the end of the Colliers Causeway section, the scenery again evolves into a rainforest setting, before arriving at a cascade waterfall.

This waterfall is, unofficially, also referred to as Slippery Dip Falls. It’s a beautiful waterfall, with the walking path ascending right next to it via a series of steps with handrails.

Soon after this waterfall, the path hits a junction with a signpost that says “Canyon” and “Centennial Glen”. Turn left at that signpost to visit the popular Centennial Grove Grotto Canyon.

4. Centennial Grove Grotto Canyon

The Centennial Grove Grotto Canyon is a slot canyon with a small waterfall at the end. This waterfall drops into a pool where you can go for a quick dip if the weather is warm.

To get to that pool, you can either walk through the water in the slot canyon, or try and walk along a narrow elevated path under a rock overhang.

In the warmer summer months, the Centennial Grove Grotto Canyon is a lovely spot to go for a splash. But as pretty as the small pool is, we also believe it has been hyped up too much on social media channels.

There are better swimming holes in the Blue Mountains with more space to move around, such as Minnehaha Falls and Jellybean Pool.

Once you’ve finished exploring Centennial Grove Grotto Canyon, retrace your steps to the junction, and make your way up the steps to Centennial Glen.

5. Centennial Glen Pass

The trail soon arrives at two more intersections, where you’ll need to follow signs for “Centennial Glen exit Bundarra St” and “Fort Rock exit Bundarra St”.

Centennial Glen is a beautiful area where you’ll walk along impressive cliff walls, a popular abseiling and sport climbing spot.

This section also includes a stunning waterfall that is a bit hidden behind the trees, but the trail navigates behind the waterfall, so you won’t miss it.

6. Fort Rock

After this waterfall, the track goes uphill quite steeply before arriving at Fort Rock, a rocky outcrop that you can climb onto.

Views from Fort Rock

The district views from Fort Rock towards the valley and surrounding headlands are pretty spectacular.

Interestingly, you wouldn’t know about those great views unless you climbed onto the big rock. And this unassuming rock is easy to just walk past and miss altogether!

7. Clifftop Walk

The Clifftop Walk starts right after passing Fort Rock, and is a highly enjoyable walking trail.

This last stretch of the Porters Pass loop walk is a fantastic way to complete this hiking adventure, with wonderful views of the Kanimbla and Megalong Valley to take in.

Towards the end of the Clifftop Walk, the path heads back into the bush, climbing to higher grounds where it meets the junction with the Porters Pass. From that junction, it’s only a short walk back to Burton Road.

We enjoyed the Porters Pass Circuit so much that we have it featured on our list of the best hikes in the Blue Mountains.
