Sundrum Castle Holiday Park is a peaceful, secluded holiday park operated by Parkdean Resorts, set within mature woodlands approximately six miles from the coastal town of Ayr in South Ayrshire, Scotland.

It sits beside the Water of Coyle, near the village of Coylton, on the grounds of a historic estate centred on a 14th-century castle later expanded into a Georgian mansion by the Hamilton family.

The park offers a range of accommodation including caravans, lodges, and touring and camping pitches, with 129 pitches in total. It holds a David Bellamy Conservation Award, reflecting its woodland setting and natural surroundings.

The wider area provides access to sandy beaches, golf courses, and cultural attractions including the Robert Burns Birthplace Museum in nearby Alloway.
