The Big Wood is one of the best broadleaf woodlands in North East Scotland. It is outstanding as an ancient oakwood, with rich lichen and diverse ground flora. The wood supports a community of woodland birds and typical woodland fauna.
 
Records show that the Big Wood has a long history, dating back to the time before the major forest clearances in Scotland. In 1505 the Thane of Cawdor was 'requested' to provide timber for King James IV. By 1640 timber was scarce due to the rising demands of fuel, tanning, shipping, mining and clearing for farmed crops. By 1658, coal became an acceptable alternative fuel to wood. In 1684, Sir Hugh Campbell of Cawdor took Pine, Oak and Cherry timber from the Big Wood to remodel the castle. His original Scots Pine beams are still sound and in place, supporting the ceiling of his 'great hall'.
 
In 1732, 920 Oaks from the Big Wood were sold for just £300 sterling. The first written reference to planting was made in 1742 when Oaks were planted 'on the banks of the brook in the wood' by the gardener. In the latter half of the eighteenth century and through the nineteenth century the Big Wood was extended. New exotic species were introduced from North America and Rhododendron made its first appearance. Little trimming and no felling was done during this time.
 
In 1953, the 'great gale' broke up the canopy of the wood. Various experts have been consulted and plans adopted. The Big Wood is now regarded with increased veneration as it has grown older and more beautiful.
