The gardens were established in 1970 following a land donation by Eric Campbell.
The collection includes rare, high-altitude rhododendron species that struggle to grow in lowland Australian climates.
The garden site was specifically chosen for its acidic, well-draining sandstone soil and natural protection from harsh winds.
It serves as a habitat for local bird species, including the Crimson Rosella and the Satin Bowerbird.
The plant collection is managed by the Australian Rhododendron Society, Blue Mountains branch.
Campbell Rhododendron Gardens is a 45-acre cool-climate sanctuary located in Blackheath, featuring an extensive collection of rhododendrons, azaleas, and maples. The gardens are built into a natural valley, utilizing the local sandstone landscape to create tiered display beds. Managed by the Blue Mountains Rhododendron Lodge, the site functions primarily as a conservation area and botanical reserve. The grounds incorporate 20 acres of native Australian bushland surrounding the managed exotic plantings. The gardens transition from high-altitude woodland to protected valley gullies, creating distinct microclimates for diverse flora. The site is a community-managed asset, relying on volunteers for its upkeep and preservation. Pathways wind through the bush to connect various ornamental display areas.

Wear sturdy walking shoes as the terrain includes sloping paths and natural uneven surfaces.
Carry a light jacket even in summer, as Blackheath's high altitude creates significant temperature drops.
Bring a water bottle and snacks, as there are limited food facilities on-site.
Do not visit outside of the primary flowering season expecting vibrant color, as the gardens are more muted in late summer and winter.
Open daily year-round, though the peak display is strictly seasonal.
No dogs allowed; stay on marked paths to protect sensitive root systems; carry out all trash.
