I have been into Ferntree and what is now referred to as Leda by locals of the area. Ferntree are about 100m from the road you were on...there is a bend in the road at one stage with a driveway leading up to a house. Stop where you can on this bend and follow the cleared area down the water. Falls are small but really pretty. In spring climbing over the top is worthwhile as the wildflowers are very pretty.
Leda falls (or what is known as leda nowdays) are best accessed by wading up the creek. Lovely way to spend a summers day. The falls are very pretty.
Both were on Taswaterfalls before i let it lapse and lost the domian
I am considering redoing the site sometime this year. I will try and dig up photos for you. For the geocachers out there that make it to Leda there is a cache hidden to the left of the falls about 1/2 to 3/4 of the way up the bank that never got released. My trusty travelling companion on that trip lost the coordinates and I have never made it back
