The National Trust has some amazing properties around Northern Ireland. Rowallane is just outside Saintfield village (about 20 mins outside Belfast).
Rowallane consists of a beautiful old house (I forgot to take photos), stable block, walled garden, toilets and café, established gardens and woodlands.
Spring is an amazing time to visit, as everything is in full bloom, including the amazing blue Himalayan poppies. The gardens and woodlands are pretty fabulous at anytime, and with the easing of Covid restrictions a full calendar of events will hopefully be back on soon.
The gardens are popular with dog walkers and families, and are generally accessible for anyone with mobility issues. Kids will love the woodlands with plenty of trees to climb and a meadow to run crazy in.
