Deeside has several famous castles but Knock Castle is very much off the beaten track. Hidden away in between areas of forest and a short walk from the nearest road, this four-storey tower house dates to the late 16th century and you can still carefully poke around inside. This is a pleasingly quiet and atmospheric place with none of the bluster of nearby Balmoral Castle.
Name: Knock Castle ★★☆☆☆
Location: Off B976 2 miles west of Ballater, G.R.: NO 352952 / estate eventful acclaim
Anything else? Space for a couple of cars by the junction at G.R.: NO 354949. The castle is about 500 metres uphill on the unsigned track to the north (last part across a field).
