Mermaids Pool & Tahmoor Canyon, Southern Highlands NSW

An excellent walk that passes through the atmospheric Tahmoor Canyon, and also visits the particularly scenic Mermaids Pool.

Mermaids Pool & Tahmoor Canyon, Southern Highlands NSW

After 13 years of bushwalking around Sydney we are still doing new walks that exceed expectations. The Southern Highlands circuit visiting Mermaids Pool and passing through Tahmoor Canyon was one such walk. I hadn’t heard of it before, but it was fairly popular so it’s evidently not a secret. Mermaids Pool is probably the most scenic pool I’ve seen in NSW, and Tahmoor Canyon was deep and very atmospheric in places. Definitely recommended.

If you are doing the walk in warmish weather then there are numerous swimming holes along the way. Mermaids Pool isn’t really one of them though, because there is no easy or safe access in or out (except maybe from the northern end, which would require entering from Tahmoor Canyon). There have apparently been a number of spinal injuries incurred at this spot.

Track notes at the end.

I particularly liked this section of the canyon, with the small stand of rainforest plants in an otherwise dry landscape.

Track Notes

Mermaids Pool & Tahmoor Canyon, Southern Highlands NSW
On a marked track the whole way, with short side trips to visit the main sights and views.

I’m still discovering good new walks in the guide book Best Walks of the Southern Highlands by John and Gillian Souter (2012 edition, although there’s now a 2019 edition out). Their books have good track notes and are in full colour. A rather dedicated volunteer(s?) also left free maps in a box on the track, and I have posted a picture of that below – hopefully you can read it.

A free map provided along the track (at the point marked ‘log book box’).

The route is marked pretty clearly with a variety of tape, metal markers and paint on rocks. We started on a dirt road near Rockford Bridge, and the junction of Rockford Road and  Charlies Point Road. From there you walk on down stream on the true right of the Bargo River, passing Bargo Falls and Mermaid Pools (with short side trips to see both of these). We then did the Tahmoor Canyon circuit anti clockwise, although it seems most people did it clockwise. Just moderately difficult with a couple of steep sections. Possibly harder if the river level is high.

Nearby Walks

If you are interested in doing more walks in the NSW Southern Highlands then have a browse through the ones I’ve done below. It’s generally not quite as picturesque as the Blue Mountains or Royal National Park, but there are a few lesser known gems to be done.

Ahearns Lookout Track, Nattai National Park

Ahearns Lookout is an alternative walk to the Starlights Trail, in Nattai National Park south-west of Sydney. There are excellent views from the precipitous cliff edge over the Nattai River Valley. Along the way there are rocky outcrops and clearings, plus occasional broken views through the trees. Well worth the only moderate effort. (more…)

Baldy Billy Peak & the Wollondilly River, Guula Ngulla National Park.

Two walks in one here, on my first visit to the recently established Guula Ngulla National Park. The name means Koala Country, and there is a population in the park, but also emus, which is the closest to Sydney I’ve seen them. There are good views over the Wollondilly River from the short ascent to Baldy Billy Peak. After returning to the main track, you descend steeply into a valley to emerge at a pleasant stretch of the Wollondilly River.

Belmore Falls Walking Track

I’d seen Belmore Falls on Instagram, and was surprised I hadn’t visited them before, because they are a very attractive two tier waterfall. The walk to see them is very short (1.8km return), and in fact we visited with my 81 year old mother-in-law in tow, and did an even shorter walk than that described on the NPWS site (just a couple of hundred metres from the car park probably). They are well worth the visit if you are in the area (Robertson in the NSW Southern Highlands), and were particular good when we visited, as there had been heavy rainfall in the preceding few days.

Bonnum Pic Route, Nattai National Park

The high quality walk to Bonnum Pic in Nattai National Park is relatively unknown, and I hadn’t heard of it until just a week before I did it. The valley and cliff views are excellent, and once you get to the cliff line the walking experience is very enjoyable, walking over rocky outcrops and eventually navigating a rocky ridge.

Box Vale Circuit, Southern Highlands near Mittagong

The Box Vale Circuit is a lesser travelled walk in the Southern Highlands near Mittagong. It follows an old mining railway cutting at first, with valley views on a short side trip. It then descends very steeply into wilderness, follows a river, then climbs back out, passing the attractive Forty Foot Falls on the way. You may well meet other walkers, but probably not in the middle half of the walk, which skirts a section of the Nattai River and feels a bit more remote. (more…)
