By car

From Sydney and the east take the Great Western Highway through the Blue Mountains. Lithgow is located at the bottom of the descent of the mountains. The Bells Line of Road from Windsor is a narrower, quieter road, that avoids the many of the Blue Mountains townships.

By train

Lithgow is the westernmost town served by Sydney's Cityrail train network. Cityrail trains to Lithgow depart every one or two hours during the day, and less often throughout the night. The train trip takes three hours from the center of Sydney and two hours from Penrith in the west.

By bus

There are several bus services every day from Dubbo, Bathurst, Orange, Forbes and Parkes, each designed to meet the trains to Sydney. These buses are run by Countrylink, Cityrail, and the local Jones Brothers Bus Company.
