weekend ride

I was thinking about doing a ride somewhere, maybe over a couple of days.
Is there any good routes from sydney, say if I took friday off work and stayed overnight friday and sat night somewhere along the way, preferably a round trip.
My girlfriend is keen to do it, I have found some routes around the hawkesbury. I just wanted to see if anyone has any experience or tips?
I’m happy to drive somewhere first. Blue mountains maybe?

Blue mountains is cold and very hilly! Pretty awesome though.
Hawksbury would be super nice :smiley:
