From Ada No.2 Mill, explore the extensive mill remnants, and the bridge over the Ada River 150m further on. Return to Federal Crossing and turn right for the New Federal Mill site. There is a stone crossing over the Little Ada River which may be difficult after heavy rain.
Leeches are common, so bring repellent.
The trail narrows and goes through dark and lush bush, slippery logs so a good level of fitness required.
