Welcome to Blue Mountains
The foothills begin 65km inland from Sydney, rising to an 1100m-high sandstone plateau riddled with valleys eroded into the stone. There are eight connected conservation areas in the region, offering truly fantastic scenery, excellent bushwalks (hikes), Aboriginal engravings and all the canyons and cliffs you could ask for.
Although it’s possible to day-trip from Sydney, consider staying a night (or longer) so you can explore the towns, do at least one bushwalk and eat at some of the excellent restaurants. The hills can be surprisingly cool throughout the year, so bring warm clothes.
