The Knockreer section of Killarney National Park is within walking distance of Killarney Town, County Kerry. This area was formerly part of the Kenmare Estate, which was laid out by Valentine Brown, the third Viscount of Kenmare. Deenagh Lodge Tearoom dates back to 1834 and was the gate lodge of the Kenmare Estate. The tearoom is a popular haunt with locals and visitors after a stroll in the park. It is located just inside Kings Bridge across from St Mary’s Cathedral.

Knockreer House, a short walk up the hill, is the Killarney National Park Education Centre and is built on the site of the original Killarney House, which was destroyed by fire in 1913. The circular walk is signposted and offers excellent views of the Lower Lake. On the circular walk there is a pathway off to the right that leads up to the viewing point on top of the hill, which provides a wonderful panorama of the surrounding countryside.
