Rocky River Road runs through farm land, forest land, conservation land and eventually leads to Mount Campbell. There is a public access easement as far as the locked gate. Check the conditions of access and if for any reason access is restricted, leave the cache for another day. If you want to go further than the locked gate, then you will need to obtain landowner permission first.
The road is unsealed and rough in places but unless your car is particularly low slung, you shouldn't have any trouble getting this far. There are some pretty awesome views to be had from this point and a feature which was crying out for a cache.
The cache is a 400ml sistema with log, pencil, eraser, sharpener and room for small swaps. Please return carefully and ensure that the cache is secured from falling out of its hiding place.
