I’m checking through various booking websites, and really, I am a little confused. The distances quoted for hotels in Kingston to the Blue Mountains seem on the ‘ low’ side! These range from 5 to 9 miles. And while they may well bring you within the limits of the Blue Mountains, you will need to travel a lot further to guest houses or the start of the BM peak hiking trail. The real figures are around 20 miles to Mavis Bank and 24 miles to the walking trail, around 1 hour and 2 hours respectively. Budget around 80-100 US$ each way.
