The time of year has finally arrived to see the famous Howth Demesne Rhododendrons in bloom! The rhododendrons were first planted in about 1850 during the time of the 3rd Earl, Thomas St. Lawrence. Additions were made regularly during his life and again by the 4th Earl until about 1909. You can now find the greatest variety of rhododendron hybrids anywhere in Ireland. We believe there are about 400 species, 100 crosses and upwards of 500 hybrids to be seen. Some of the more commonly seen here are Ponticum, Thomsoni (introduced by Trinity College in about 1870) and Edgworthi (a tender species from the Himalayan foothills).
Nestled amongst the rhododendrons you will also find Aideen's Grave and continuing beyond the growth, you will reach the summit of Muck Rock for wonderful views across the bay. You can find the rhododendrons towards the summit of the estate by heading up the drive from the main gates, passing the castle on your right eventually you will reach the Deer Park Hotel and Golf Club. On the right of the Café Bar you will find a gravel path under an avenue of cherry trees at the end of which you will see the beginning of the Rhododendron Walk.
