A network of meandering trails leads through this lovely arid zone botanic garden (opbg.com.au; free), which was founded by the prominent anthropologist Olive Pink. The garden has more than 500 central Australian plant species, including bush foods and medicinal plants traditionally used by Arrernte people, such as native lemongrass, sour quandong and emu bush.
There's a gentle climb up Meyers Hill with fine views over Alice and Ntyarlkarle Tyaneme, one of the first sites created by the caterpillar ancestors. It also provides habitat for 80 bird species and the black-footed rock wallaby.
The small visitor center has various exhibitions during the year, and the excellent Bean Tree Cafe alone is worth a trip to the gardens.
