Mussenden Temple and Downhill Demesne is an extraordinary historic estate that stands out as one of the best things to do with kids in Castlerock and along the Causeway Coast. Perched dramatically on a 120-foot cliff edge overlooking the Atlantic Ocean, this 18th-century classical rotunda was originally built as a summer library for the Earl Bishop. It operates as a heritage outdoor site where families can explore grand historic ruins, vast coastal gardens, and natural cliffside paths.

Parking is £10 per vehicle at Lion's Gate (free for National Trust members). The interior of the temple itself is closed to casual visitors but accessible during special events or private bookings.

If you are looking for the best place for a day out with family and kids, this dramatic cliff-top estate offers an unbeatable blend of history, fresh air, and legendary views. Children can run through the ruined halls of Downhill House, explore secret walled garden paths, and watch trains emerge from the historic tunnels below. It is an inspiring outdoor destination that turns a scenic coastal walk into an exciting historic adventure.
