The Blue Mountains were named in 1788 when officers in the First Fleet observed a blue haze rising from the valleys — a phenomenon caused by fine droplets of eucalyptus oil refracting sunlight across a million hectares of forest.
For decades the sandstone escarpment blocked inland expansion until 1813, when Blaxland, Wentworth and Lawson traced a ridge-top route that became the foundation of the Western Road. By the 1870s rail access transformed the high country into a weekend retreat for Sydney families seeking cool air and panoramic views, and the grand hotels of Katoomba and Leura trace their origins to that era. Today the Blue Mountains National Park protects more than a quarter-million hectares of wilderness, its western boundary pressing against the Wollemi and Kanangra ranges.
Three Sisters rock formation above Jamison Valley remains the most photographed landmark in the range, its three sandstone pillars visible from Echo Point and reached by the Scenic World cableway network. Govetts Leap near Blackheath drops 180 metres into the Grose Valley, where eucalypt canopy stretches unbroken to the horizon. Wentworth Falls descends in three tiers across a 300-metre cliff face, and walking tracks thread through cool-temperate rainforest along its base. The park shelters endemic species including the Wollemi pine, discovered in a remote gorge in 1994 and now among the rarest plants on earth. Lyrebirds, crimson rosellas and yellow-tailed black cockatoos inhabit the mid-altitude forests, and grey kangaroos graze open slopes near Glenbrook and Woodford.
Blue Mountain day tour Sydney itineraries depart central hotels each morning and follow the Great Western Highway through Parramatta and Penrith before ascending the escarpment at Lapstone. Most routes include a stop at Featherdale Wildlife Park or similar facility, then proceed to Katoomba for guided walks around Echo Point and lunch in Leura village. Afternoon hours typically include a Scenic World ticket for the railway, cableway and skyway circuits, which traverse clifftops and canyon floors within minutes. Return journeys reach the CBD by early evening, completing a circuit that crosses sandstone plateaus, temperate valleys and urban fringe in a single day.
