Jenolan caves was a fantastic experience with lots of diffused lighting and etherical music. However it seems to be becoming a bit commercialised and care needs to be taken to protect it It seems to be a bit orientated towards money more than service to the tourist industry.

Visited the caves this year as part of a family holiday. We went in the winter time and it was freezing. You definately need a couple of days here to explore all of the caves and you need to get there early in the morning to be guaranteed a spot on one of the many tours. It doesn\'t matter if you do the tour at nighttime or daytime as it all looks the same on the inside. Some of the stair climbing buggers you but it is well worth the walk. Try to get a package deal with the tours cause it can end up very expensive if you book tours separately.

We visited the caves when we were kids for a school excursion - they were awesome.

Best times to visit are late spring and throughout autumn.

Spot on about going there early so you may be able to catch 2 caves as a better package deal - but they are set at scheduled times throughout the day, so expect to spend some time lazying about and potentially spending $ to boost the local tourism $. On a regular basis, there are musical performances in the caves as well making use of the acoustics in the cave. I\'m yet to go for one, at least it\'s not too far off from Sydney.
