At Portumna Castle and Gardens · Portumna, Co. Galway, H53 YK27
For the whole of August 2026, the OPW is running a pilot scheme giving free admission to everyone under 18 at its fee-paying heritage sites nationwide, and Portumna Castle and Gardens is one of the Galway sites taking part. Children must be accompanied by a paying adult, and pre-booked tickets are required to manage numbers for the duration of the scheme. Portumna Castle was built in the early 1600s by the fourth Earl of Clanricarde as the power base of the de Burgo family, and its design blends late-medieval and early Renaissance style. A major fire in 1826 left it a roofless shell for well over a century before state restoration began in the 1960s, and that work is still ongoing today. The ground floor is open to visitors and holds an exhibition telling the story of the castle and the de Burgo family. Outside, the walk up to the building passes through restored formal gardens, with the walled kitchen garden the highlight, and the site looks out over Lough Derg. It sits right beside the River Shannon and Portumna Forest Park, so a castle visit can easily be combined with a walk or cycle in the forest afterwards.
Portumna is in the south-east corner of County Galway, on the shore of Lough Derg where the River Shannon widens, roughly an hour and a quarter’s drive from Galway city via the M6 and R355/R353. The castle sits at the edge of the town, next to Portumna Forest Park, with on-site car parking. There is no direct rail link to Portumna; the nearest stations are Athlone or Ballinasloe, from where a car is needed to complete the journey.
