a few friends and I are kinda locked in date wise to do the trek friday-sunday 18-20 March. Would love to find a way to reach the caves if possible walking an alt route as finishing at the Jenolan Cave Cabins might be a bit of an anticlimax.
happy to tack on a few more hours to day 3 to get to somewhere like the jenolan river fire trail or something, but unsure if that is operational at the moment.
thanks in advance

Many years since I walked the SFT (in the opposite direction). Yes it looks like the only practical option would be via the McKeown's Valley track/Jenolan River, assuming there's a connecting track from the cottages. Or a (sensible) route that can be followed. It only looks a km or so in between but I wouldn't want to scrub bash the whole way.
McKeown's Valley track appears to be open but they only list a very short version of it -
https://www.nationalparks.nsw.gov.au/things-to-do/walking-tracks/mckeowns-valley-walking-trackI know that area was badly affected by the fires so it may only be partly accessible. Suggest ringing the cottages/caves (same contact number) who may be able to help.
Otherwise try NPWS at Blackheath/Govetts Leap, as they also act as the tourism/advice bureau for the region. Best to get hold of someone with relevant local knowledge (not always possible).
