Bungonia National Park is in the Southern Highlands region of New South Wales.
The park sits across the traditional lands of the indigenous Njunawal group, the northwest corner of the Wandandian tribal region, and the southern boundary of the Gandangara tribal group. The prominent ridge tops are considered historically significant travel routes for tribes who moved with the seasonal harvest. However, archaeological evidence of campsites has been found on the main plateau, along with limestone dolines that contain the remnants of edible plants consumed by Aboriginal peoples.
The establishment of European settlement in this region began around the 1820s, with Goulburn settled in the 1840s and the town of Bungonia set to be created in 1832.
The park was initially established as a water reserve in 1872, to protect the water supply extracted from the Shoalhaven River and in the same year, a visit was reported to the Drum Cave and the Sky-Light Cave, named after the sound made when a stalactite was struck and the large hole in the roof, respectively. Multiple minor explorations of the park were made by Europeans throughout the late 1800s, to explore the many cave systems which were prominent features of the area.
Visitor records for the park began in 1892 when 85 visitors were recorded. By 1899, this number had increased to 559, with exploration of the caves costing 15 pounds per party "candlesticks provided".
The average summer temperature in Bungonia National Park is between 12 and 26°Cs with the highest recorded temperature being 40°C. Due to its increased altitude and inland southerly position, the park receives a very cold winter temperature. On average the temperature sits between 1 and 14°C with the lowest ever recorded temperature being -9°C. Average rainfall in the region is around 665 mm with most precipitation occurring in March and the least in September. The highest recorded rainfall in a single day is .
The park can only be reached by car. If you're going on the M31 Hume Hwy, exit on Jerra Rd, just south of Marulan, and head down till Bungonia and then turn onto Bungonia Access Road, where you should continue heading up north from there.
There is a fee of $8 in Bungonia National Park and can be paid off at the ticket machines.
Caving is a popular activity in the park with hundreds of caves open to explore throughout the year. Access to many of these caves is via ladders or by anchored ropes which allows their use by experienced and inexperienced cavers alike with several of the larger caves include the Drum Cave and Grill Cave, but there are other smaller caves in the park such as the Blowfly Cave, Argyle Cave, Chalk Cave, College Cave, Canberra Hole, Fossil Cave, Spider and dozens of other unnamed caves. However, be warned that dangerous levels of carbon dioxide are often present in these systems, especially during the summer months.
There are a number of hiking trails in this park, although there aren't many compared to other parks. Such include the Green track, a 6.7 km trail going through some of the bushy areas of the park, or the Molly O'Neill nature track, a simple 0.3 km walk around a picnic area.
There aren't any cafes, restaurants, eateries, kiosks etc., and you'll need to bring your own food.
