I was hoping to get some advice from the group... I've learned so much from reading the forums. thanks to all! My family and I plan to go visit the Blue Mountains for a 2 night trip. What's the best way up? Train, bus or car? And what are the roads like? Is it scary, with zig zag roads, where you drive right beside cliffs (or whatever you call them?). Will be travelling with grandma who is scared of heights and she doesn't want all of us to go to BM. But the rest of the group want to see this World Heritage site, so in order to convince her to come, we have to make sure that the roads are not steep and scary on the way up... Thank you very much in advance.
