Castlefield lies on the River Ive as it flows between High Head Castle (a Tudor and early Georgian ruin) and Thistlewood Pele Tower (15th Century). The old estate has left its mark on the landscape with old drinking troughs, bridges, ancient individual oaks and coppices. The river valley has a wide range of habitats including sandstone gorge, sandy haughs, bog, a bluebell wood, and a wooded ghyll with extensive badger setts. Forty species of tree grow on the farm. The livestock on the farm consist of a closed herd of Belted Galloway suckler cows and a flock of pure-bred Scottish Blackface sheep.
