Grey Mare's Tail is a waterfall on Ferntree Glen Creek, St Mary's, Tasmania, Australia. It only flows in wet weather. A short walking track from St Mary's Pass leads to a lookout with views of the Esk Highway in one direction and views of the falls in the other. This is a good place to stop and stretch your legs if you are driving through St Mary's Pass.
This Tasmanian waterfall should not be confused with the Grey Mare's Tail waterfall in Scotland.
