Mussenden Temple (Castlerock)

Perched dramatically on a cliff edge overlooking the Atlantic Ocean, Mussenden Temple is a stunning 18th-century circular building inspired by the Temple of Vesta in Rome. It forms part of the Downhill Demesne estate and is a must-see landmark on the Causeway Coastal Route. Families can enjoy panoramic coastal views, explore the nearby ruins of Downhill House, and run along the sandy Downhill Beach below. The site is free to visit and open year-round, though access may be limited in bad weather due to exposed paths. Best for: All ages (supervise young children near cliff edges). Facilities: Small car park (fee applies), no toilets or café on site; nearest facilities in Castlerock village (1 mile). Tips: Combine with a walk on Downhill Beach or a visit to the Bishop's Gate. Arrive early to avoid crowds. Sturdy footwear advised for uneven ground.
