Summary: The Natural Bridge Loop combines the Natural Bridge Track and Currie Road Trail to form a short loop. The bushwalk crosses a natural sandstone bridge and goes down to the water at Bantry Bay via the Cook Street Trail.

After completing the Bantry Bay Loop in Garigal National Park to the east the previous day, and Flat Rock Beach Circuit to the west a few days before that, I’m back to do the Natural Bridge Loop. This is the bit in the middle between Bantry Bay and Flat Rock Beach, which includes the Natural Arch Track and Cook Street Trail.

Currie Road Trail 

Starting at Currie Road, I take the Currie Road Trail, a wide service track.

Passing the junction with the Natural Bridge Track on the left, I continue along Currie Road Trail up to the Cook Street Trail. 

Cook Street Trail

The Cook Street Trail descends to Bantry Bay. Like most of the trails around here, it’s a shared bushwalking and mountain biking track. Running parallel to the Cook Street Trail is the Serrata Mountain Bike Trail, a purpose-built and fairly challenging mountain-biking single-track.

At the end of the service trail, a narrow walking track descends quite steeply down to the water, with the last bit dropping steeply past some large boulders.

It’s low tide, so at the bottom of the Cook Street Trail there’s a wide expanse of something that’s somewhere between mud and sand. On the opposite side of Bantry Bay is the Bay Track, and further down along the bay are the historic buildings from the old Bantry Bay Explosives Magazine complex.

It’s back the same way, returning up the Cook Street Trail and then along the Currie Road Trail to the Natural Bridge Track, which I turn onto.

Natural Bridge Track

The Natural Bridge Track is a pleasant bushwalking track, which winds down through the tall eucalpyt forest to an unnamed creek.

The track crosses this unnamed creek over the “Natural Bridge”, a sandstone arch that has been formed by water erosion over thousands of years.

The track then ascends the other side of the valley to the Bay Track (also known as the Bluff Track).

Bay Track / Bluff Track

Having reached the Bay Track, I make a small off-track detour to re-visit the Bluff Track Whale Aboriginal engraving site, which I couldn’t see very well on my last bushwalk (I reached them after sunset and the light was rapidly fading). In the afternoon sun I could clearly make out a large whale described back in 1899 as “about thirty-four feet long, with an excessively widely-opened mouth, and almost within its jaws is a man-like deity with straight upraised arms and straight legs” (W.D. Campbell).

I later discover that this engraving has been used for artwork on the concrete wall of the Warringah Freeway near the Willoughby Road overpass.

Once back on the Bay Track, I continue along a well-defined, but unnamed, walking trail that soon crosses another wide and long rock platform. Someone has constructed a rough border with sticks to protect around another Aboriginal engraving. Although I can still make out that it’s a kangaroo, it’s quite weathered.

From this rock platform it’s pleasant walking along the narrow bushwalking trail to reach Currie Road, completing the loop.

The track finishes on Currie Road near Forestville Park, home of the Forestville Ferrets – a rugby league club for Junior and A-Grade players. The road, closed to traffic, passes the oval to reach a locked gate where I left the car.

More information on Natural Bridge Loop

The Natural Bridge (reached bia the Natural Bridge Track) is the main attraction of this loop walk. If you just want to see this it’s 1.4km return walk from Cook St (Forestville). The longer Natural Bridge Loop described here adds a visit to the water at Bantry Bay, and it’s worth continuing a very short distance down the Bluff Track to an impressive lookout.
