Starting from Ridgeway Road in Blackheath.  Park at locked gate.  Burramoko fire trail is a wide path undulating to Baltzer Lookout. Steep up and out to Baltzer lookout on a point. You can walk down the stairs - very rough track (Grade 4) and tricky underfoot to reach a point where you can see Hanging Rock from below.  Not a good walk to do if windy or the faint hearted as it is beside a cliff from the lookout onwards.
Had morning tea at Baltzer lookout and walked back along Burromoka Fire Trail to cars. Then drove on to lunch at the Campbell Rhodendrum Garden where there are toilets and picnic tables and lovely gardens (donation required). 
Free time for the rest of the afternoon - some choosing to shop, some to Mount Blackheath Lookout and Hargreaves Lookout.
