short distance west of Rannoch Forest lies The Black Wood of Rannoch, a
Caledonian Forest Reserve. This special place is rich in native tree
species and supports a wealth of plants, insects, birds and animals.
Today the wood is peaceful, but in a time long gone it sheltered outlaws
and caterans (cattle rustlers) who made it the base for their notorious
operations. Remnants of canals, constructed in the 17th century to
assist in the clearing of timber, can also be seen in the woods.
