In response to dee_legg's post on the "Lees Paddocks Track Bridge Down" topic, here's some info about Little Fisher.
This route into the northern end of the Walls of Jerusalem has been popular with trappers and fishermen for some time. Once the Walls of Jerusalem really started taking off as a bushwalking destination local walkers started to use the less crowded Little Fisher instead.
The track is accessed from the Mersey Forest Road on Lake Rowallan's eastern shore turning left into Dublin Road before the Fish River, then right into Little Fisher Road, right into Little Fisher Spur 1 then immediately right into Little Fisher Spur 1-1. (I was last there 10 years ago so signage and overgrown roads may have changed these directions.)
The walk is described in The Abels for access to Turranna Bluff and Mersey Crag. I think it may also get a guernsey in John Chapmans new edition of his Overland Track book where he describes almost every 'trackless' route into the Walls imaginable. Not surpirisingly, the area is rapidly becoming less 'trackless.'
Once National Park and World Heritage status stopped logging in the upper reaches of the Little Fisher, it was no longer practical to maintain the road all the way in so a second bridge over the river was allowed to collapse. Consequently the walk commences with a bit of road-bashing, then a short section of regrowth before the myrtles herald the upper extent of logging. Before long the waterfall mentioned by dee-legg is reached.
The fall has appeared on posters and in publications as either Little Fisher Falls or Rinadeena Falls. If people take The Abels' advice and return from Mersey Crag by following this stream down from the plateau, a number of interesting small falls and chasms await discovery.
Once the upper limit of rain forest is reached, the valley broadens briefly before another short climb to the plateau at Long Tarns, the northern boundary of the Walls of Jerusalem NP. At this point, you are half a day's walk from Blue Peaks, The Higgs Track and the Walls themselves.
