Yalwal is the site of a former gold mining town of the same name situated 29 km (18 mi) west of Nowra at the confluence of the Dangera and Yarramunmun Creeks which then forms Yalwal Creek which flows into the Shoalhaven River. It is now the site of a City of Shoalhaven managed picnic area and Dangera Dam.

Prior to European settlement this was Wandandian Aboriginal land.
Mining
Gold was first discovered in the area by Rev W.B. Clarke in 1852. Successful sluicing operations began in 1870 by J. Sivewright and party but were disrupted by the great flood of 1871. In 1872 open cut mining operations were begun at the Pinnacle when the main reef was discovered. The first shafts were sunk in the Homeward Bound mine in 1872 with payable gold found in 1874. In 1875 the first stamp battery (5 head) was erected. In 1880 a mail receiving station was opened and in 1884 a public school opened, it closed in 1918, reopened in 1924 and finally closed in 1928.
Yalwal Post Office opened on 1 January 1883.
In 1895 the nearby Grassy Gully mine was discovered. In 1990 all the usable scrap iron in the town was bought by scrap dealers from Nowra. Further dismantling of the town occurred during the First World War when building materials were used for the war effort.
1934 was the last discovery with the Fountainhead.
In 1939 devastating bushfire destroyed most of what was left of the town with only one residence, one shop and the Post Office surviving. There was one fatality. Mining operations after the fire dwindled until 1971 when the Shoalhaven Council finished construction of the Danjera Dam which flooded most of the former town site and the lower mines.
Some mine shafts and other diggings, the graveyard (the oldest grave dated 1854) and a stamping battery (five head) can still be seen. Of the 35 or so mine workings accessible by foot (or canoe) some are safe enough for a young child to walk and climb through whilst others are extremely dangerous. If in doubt, don't enter. The main mine workings are about 15 minutes walk from the car park and can entertain for the entire day. There are two maps of the mines known to be in existence with the latter from the mid-1990s, prepared by a local surveyor/town planner is considered the most accurate.
The area is now the site of Danjera Dam a part of the Shoalhaven water supply and the site of a picnic area. Canoeing and swimming are allowed on the Dam but power boats are prohibited. The Dam stretches 7 km to the south with some good bass fishing. The previous beautiful upstream grassy river banks have been lost due to a lack of cattle grazing, these areas are now overgrown with blackberries.
The valleys of the area cut into Devonian quartzite and phyllites while the plateau consists of Permian sandstones. Rhyolite and granite also outcrop in the area. Carboniferous granite intruded into the Upper Devonian sediments and the gold deposits are a result of replacement and impregnation by siliceous solutions bearing gold and sulphides. Silver, copper, tin, lead, arsenic and zinc ores have also been found in the area.
