"The only botanic garden in a UNESCO World Heritage Area, the lush Blue Mountains Botanic Garden conserves the cool-climate plants of lofty Mount Tomah. Covering 622 acres, with 70 open to the public, the grounds are home to around 900 global species spread over diverse gardens, though they especially champion Southern Hemisphere plants. Don’t miss the famous Wollemi Pines along the Gondwana Walk—you'll see plant groups that stretch all the way back to Gondwana, the super-continent dating back 80 million years." - Sophie Davies
