Altamont Gardens in Co Carlow are an enchanting blend of formal and informal gardens with riverside walks covering over 40 acres (16 hectares). The estate gains much of its character from the many mature trees, natives in the avenues and woodland areas, and exotic specimens throughout the gardens. Lawns bisected by sculpted yews slope down to a lake surrounded by rare trees and rhododendrons and lead in turn to a very different garden featuring exotic shrubs and trees.A fascinating walk through the Arboretum, Bog Garden and Ice Age Glen with its canopy of ancient oaks and huge stone outcrops leads the visitor to the River Slaney. When Corona North, who lovingly cared for the gardens for over 50 years died in 1999, the gardens were left to the State at her request. Ongoing restoration and maintenance continues under the stewardship of the Office of Public Works
