Open year-round (free, no formal hours), visitors can view the ruins from nearby paths, as access to the castle itself is restricted due to private ownership and safety concerns.

Limerick has minor castle ruins like Castleconnell Castle (15th-century, on the Shannon, private and heavily ruined), Kilmallock Castle (Dominican Priory gatehouse, often mislisted as a castle, free but minimal), and Glin Castle (18th-century mansion, now a luxury hotel, limited public access). These are less prominent due to their state or restricted access. Bunratty Castle, often associated with Limerick, is in County Clare.
Limerick’s castles offer diverse experiences, from King John’s urban fortress to rural ruins like Carrigogunnell. King John’s and Desmond are the most visitor-friendly, while others cater to niche interests.
