Cleeves Cove cave, the site of the Elfhame, is said to be connected to Loudoun Hill. It is reported that once the Laird of Auchenskeich's collie dog entered the cave at its entrance above the Dusk Water and came out at Loudoun Hill near Darvel, many miles away. The end of the Cleeves Cove system is said to have never been found. Mauchline Castle is said to be linked to Kingencleugh Castle by a tunnel.
