On your Dublin visit be sure not to miss the magnificent Botanic Gardens in Glasnevin. Located near city centre just 3 km from O Connell Street, the National Botanic Gardens are an oasis of calm and beauty, and entry is free. A premier scientific institution, the gardens also contain the National Herbarium and several historic huge wrought iron glasshouses. An ideal half day would combine a visit to the gardens followed by a tour of the adjoining historic Glasnevin Cemetry. For opening hours and further information visit the Botanic Gardens web site.
