From the vibrant heritage gardens of Mount Wilson to the sweeping lookouts and walking trails of the Blue Mountains National Park, the region offers an enchanting escape all year round, but especially during autumn. But beyond the usual circuit of local favourite spots, there are plenty of quieter alternatives where you can escape the crowds and still make the most of the season. One such destination is the Blue Mountains Botanic Garden at Mount Tomah. Located a short and scenic drive from Sydney, the 28-hectare estate sits on a basalt cap roughly 1,000 metres above sea level, making it not just the highest botanic garden in Australia, but in the Southern Hemisphere. Autumn is one of the best times to visit, with cooler temperatures and vibrant seasonal colour appearing across several parts of the garden; here is everything you need to know for a visit.
Blue Mountains Botanic Garden, Mount Tomah

Spread across 28 hectares, it is the only botanic garden of its kind in the world located within a UNESCO World Heritage Area and home to a spectacular range of cool-climate plants from Australia and overseas. Although expansive, the layout is easy to navigate winding past a network of paths linking distinct garden areas, open lawns and lookouts. Among the primary features is the Rock Garden, currently recognised as the largest collection of its type in the Southern Hemisphere. It houses a diverse range of alpine plants from South America, South Africa, and New Zealand, offering a true global perspective on high-altitude flora.
Also impressive is the Ornamental Garden which forms one of the main sections, with structured plantings and seasonal displays throughout the year. The garden also features a dedicated Woodlands area, with paths lined with towering Giant Sequoias and Redwood trees. While much of the garden remains evergreen, the Formal Garden and Residence Garden are specifically designed with deciduous trees and Japanese maples that provide the most concentrated displays of autumn colour during April and May.
The Plant Explorers Walk offers a quieter route through 400 species, including the Wollemi Pine, a rare “living fossil” from the age of the dinosaurs. Nearby, the World Heritage Viewing Deck provides a direct look over the wilderness and stunning mountain views.
