Katoomba is approximately 1 hour 45 minutes drive from Sydney domestic airport.
Depending on traffic, stops etc. it is a good idea to allow 2 to 2 hours 30 minutes for your drive. To plan your drive, the Whereis website is a good resource.
There is also a train service from the airport. It only takes about 11 minutes to travel to Sydney’s Central Station, and from there you can catch an Intercity Train to Katoomba. The total trip from the airport is approximately 2 hours 20 minutes, depending on connections. You can plan your rail trip and find timetables etc. on the Transport NSW website.
Your Relationship Rescue sessions are held in my private clinic in North Katoomba, which is just over 1km from Katoomba railway station… about 15 minutes walk.
