Lismore Castle’s gardens are in Lismore, County Waterford, south of Cahir across the Knockmealdown Mountains. The gardens and Lismore Castle Arts can be combined in a day trip.
The upper and lower gardens
The official gardens guide describes two gardens within the castle walls, covering about seven acres.
The upper garden includes ornamental and productive planting, with vegetables, herbs, fruit and flowers. The lower garden has informal paths, trees and shrubs, lawns and a yew avenue. Contemporary sculpture is also displayed in the grounds.
Opening and tickets
Lismore Castle Arts publishes its opening season, ticket details and exhibition programme on its website. Its listed 2026 season runs from 13 March to 25 October, checked on 19 October 2026.
Check the date you want to visit, the last admission time and what your ticket includes. Review the operator’s accessibility information if steps, slopes or surfaces affect your visit.
A garden ticket should not be assumed to provide access to the private rooms of the castle.
Travelling from Cahir
Plan the road journey using current mapping. A route through Clogheen and over the Vee takes you through the Knockmealdowns; allow time for bends, weather and any stops.
Use designated parking places for views and keep entrances clear. Check your return route before setting off if you are travelling late or in poor conditions.
