Mount Tomah Botanic Gardens is located between Lithgow and Richmond, north of the Blue Mountains.

Mount Tomah is the cool-climate garden of the Royal Botanic Gardens Sydney. It covers 28 hectares on the summit of a basalt-capped peak 1000 metres above sea level in the rugged Blue Mountains.

The theme of this Garden emphasises cool-climate plants from around the world, especially those from the southern hemisphere.

A walk round this 28 hectare garden takes you past the rhododendrons of the Himalayas and western China, the southern beeches of Australia, New Zealand and Chile, the giant lobelias of Mount Kenya, the proteas of South Africa, and the conifers of Europe and North America, to name but a few.

As well there is also an impressive collection of cool-climate garden plants. These have been arranged in traditional fashion, as in the Formal Garden and Residence Garden. All of this has been established on an impressive site with panoramic views over the mountains to the north, making it an ideal place to learn about and enjoy the beauty of plants from the principal montane regions of the world.
