Other months in Kakadu

Swim only where it is checked
1 Jan – 31 DecRiskSaltwater crocodiles move all over the park with the water, and rangers survey and clear the few plunge pools that open each dry. Everywhere else is closed to swimming, permanently and for good reason. Source ↗

Dry season
1 May – 31 OctCrowdedFrom May the floodplains drop, the unsealed roads dry out and the park opens up properly. Bininj count six seasons here, not two, and this covers three of them.
- Rule
Park pass, dry-season price
15 May – 31 OctEveryone needs a pass and it costs more in the dry than in the wet (an adult pass is $40 in the dry, $25 in the wet). Buy it online before you drive in; the ranger stations are a long way apart and there is no boom gate to sell you one. Source ↗
- Nature
Birds crowd the last billabongs
1 Aug – 31 Oct · usuallyBirdlife seasonAs the floodplain shrinks, magpie geese, jabiru and whistling ducks pack onto what water is left. The late dry is when the Yellow Water cruise is at its best and the heat at its worst.
- Festival
Mahbilil Festival
20 Aug – 10 Sep · usuallyMajor festivalA one-day festival on the lake at Jabiru at the end of the dry: music, weaving, bush foods, spear throwing and a magpie-goose plucking competition, run by and for the local communities. Source ↗
