The Australian Outback centres on Uluru-Kata Tjuta National Park's red sandstone monolith, Kings Canyon's Rim Walk, Alice Springs as the Red Centre's hub, and Kakadu National Park's wetlands and Aboriginal rock art galleries.
Cool dry season with Uluru and Kings Canyon walking pleasant, Field of Light installation at Uluru ongoing, and Kakadu accessible without monsoon road closures.
Outback dry season with Alice Springs Camel Cup mid-July, Kakadu and Litchfield National Park 4WD tracks open, and Larapinta Trail walkable in cooler temperatures.
Hot wet season with Uluru hitting 38°C and walking dangerous after 11am, Kakadu's wetlands at peak with monsoon rains greening the country, but many roads cut by floodwaters.
Coldest desert nights with Uluru sunrise temperatures near freezing, Field of Light Solar at peak photogenic, and Alice Springs Beanie Festival drawing knitters from across the country.
