The next day we headed for Katherine stopping at the thermal springs at Mataranka along the way. We didn’t go in the water as the pool is about 2 metres deep. The water there is a constant 32 degrees.
We found another thermal pool in the Katherine river and it wasn’t deep, so we spent a couple of hours in the lovely warm water there (32 degrees again) cooling off from the current August heatwave. It was 36 degrees.
