Killarney House is a substantial country house at the entrance to Killarney National Park, just a few minutes' walk from the town centre. The house was the residence of the Earls of Kenmare and has been restored as a visitor centre for the national park. Exhibitions inside describe the park's natural history, geology, and the human history of the Kenmare estate.
The grounds around the house are particularly attractive — formal gardens with mountain views and direct access to the national park trails. Entry to the house and grounds is free. The walled garden, restored to its Victorian-era planting scheme, is one of the best in Kerry.
