CAUTION: As of 16th December 2017, the log bridge at the chasm was missing, making the track beyond that point impassable. Signs at the car park and on the track warned about this. Do not attempt to walk from the Mother Cummings Rivulet car park to Ironstone Track or Dell Track.
Smoko Creek is near Meander, Tasmania, Australia. This video follows the walking track from Mother Cummings Rivulet to the three waterfalls on Smoko Creek. The last of these enters the eponymous chasm.
