Gnaala Mia is a new area just up the hill from Congelin Dam and the camping area there..
The Dryandra Area in general is a great place to do some great picnicing, walking and exploring through the woodland from the Arboretum, Contine Hill, and Old Mill Dam areas, as it is a hotspot for native flowers and wildlife.. Lions WA also have forestry cottage accomodation out here, and there are nocturnal walk and wildlife tours to do as well.
The cache is a simple mid size camo sistema hidden out along the 3km walktrail loop. The walktrail starts and finishes at the Gnaala Mia entry station but you can make a quick walk and grab from the western end of the southern camping loop..
Enjoy..
