Very private valley nestled between two mountainous sandstone ranges. 3.5 kilometers from Colebrook, via Yarlington road. The property in total size is 37 hectares half of which is gently undulating grassland slopes. These slopes lead to the banks of the beautiful Iles Creek which runs nearly all year round. The western range across the creek includes numerous caves within comfortable walking distance. The highest cave provides magnificent views to the East coast.
Camping options include non-designated sites either side of the creek under the huge black-wood trees, restricted to 4-wheel drive vehicles during winter and spring months, with a secluded site with year-round access for all vehicles.
At the entrance sits the first of the designated sites, the rest are accessed via the meandering road down 300 or so meters to the camping ground entrance for the other two sites. The last 500-700 meters of Yarlington road leading to the entrance is quite steep. Some two wheel drive vehicles towing large vans have found this challenging, while others haven’t.
The two main camping areas now have a ‘bush loo’ in each site.
