Track grade

Grade 2 (Easy) - A Gentle Introduction to Inclines: Grade 2 on the AWTGS represents easy walking tracks that offer a slightly more challenging experience compared to Grade 1. Similar to Grade 1, no prior bushwalking experience is required. The track surface is typically hardened or compacted and may have gentle hill sections or occasional steps. The total distance of a Grade 2 walk is typically no greater than 10 kilometers. These walks are still suitable for families with a bit more experience or those seeking a gentle introduction to some inclines.

About the region

Judburra Gregory National Park, the second largest in the Northern Territory, offers a stunning diversity of landscapes. Explore gorges, escarpments, sandstone formations, monsoon rainforests, and eucalyptus woodlands. Be aware that saltwater crocodiles inhabit all waterways in the park, so swimming is prohibited. Always practice crocwise behaviour.

Immerse yourself in the rich Aboriginal culture. The traditional owners consider this land a vital part of their identity with deep spiritual significance. Numerous archaeological sites and a wealth of rock art, featuring painting, stenciling, and engravings, showcase a long history of Aboriginal occupation. The park encompasses the traditional lands of several Aboriginal language groups, and ceremonies and rituals are still practiced here.

For the active visitor, there are walking tracks catering to all fitness levels. Adventurous types can tackle the 4WD tracks. The dry season (May to August) provides comfortable weather, but the park remains open during the wet season (November to April) if you prefer lush landscapes and fewer crowds.
