I did the full loop of the first bassin and duck reach track hikes and had an amazing time! The duck reach track (if passing by the power station) definitely starts off muh harder, with a bunch of narrow stairs and narrow dirt pathways following one-another in succession, with a pretty quick change in elevating. However, I highly recommend doing the full loop!
While the irst bassin track provides great views of the gorge, the duck reach track really brings you into nature (without the fencing and everything that makes the first bassin track feel a little more "contained").
During the duck reach portion, I had the great pleasure of meeting a bunch of different animals, notably a very curious echidna that made me add another 10 mins to the duration of the hike.
As for the duration, the estimates provided on the signs are fairly accurate if you take your time or get distracted by nature, but for the portions where I was walking briskly, I'd say you can shave 25% off easily.
