Overview
Altamont Gardens sits on a 100‑acre (≈ 40 acre of cultivated ground) estate on the banks of the River Slaney, just off the N80 between Tullow and Bunclody. Described by the Office of Public Works as the “jewel in Ireland’s gardening crown”, the garden blends formal lawns, sculpted yew avenues and a romantic lake with wild‑flower meadows, an arboretum and a series of historic woodland walks. The site is open year‑round, and entry is free, making it an ideal stop for families, botanists and anyone seeking a peaceful escape in the Irish countryside.
History
The origins of Altamont stretch back to at least the 16th century, when a fortified house stood on the site. By the late 18th century the estate had acquired the name Altamont, possibly linked to the Marquis of Sligo. Significant alterations were made by the St George and Doyne families in the 1740s, including the creation of the grand semi‑circular avenue of beech trees that still frames the front of the house.
The garden’s modern character owes most of its development to the Watson family, who purchased the property in the 1920s. Feilding Lecky Watson introduced a substantial rhododendron collection, and his son‑in‑law, Corona North, devoted the next five decades to restoring the over‑grown estate after World War II. She oversaw the hand‑digging of the lake, the planting of the iconic Myshall Gate, and the creation of the Bog Garden, Ice Age Glen and the extensive arboretum. After Corona’s death in 1999 the estate was bequeathed to the State, and the OP W now maintains the gardens while preserving her vision.
What to See & Do
The Yew Walk and Lake Loop
A signature feature is the ancient yew walk – a 300‑year‑old avenue of towering yews that forms a dramatic, tunnel‑like promenade. From there the path descends to the man‑made lake, framed by mature oaks, beeches and chestnuts. Stone bridges and a series of benches provide perfect spots for quiet contemplation or photography.
Arboretum, Bog Garden and Ice Age Glen
The arboretum showcases a remarkable collection of native and exotic trees, including Japanese maples, a fossil‑tree Metasequoia and a handkerchief tree (Davidia). The adjacent Bog Garden offers a wet‑land experience with moss‑covered stonework, while the Ice Age Glen presents a canopy of ancient sessile oaks, some over 500 years old, and a series of hand‑cut granite steps that lead down to the River Slaney.
Walled Garden & Plant Sales
Tucked behind the house, the Victorian‑style walled garden is a showcase of herbaceous borders, rare roses and a herb garden stocked with culinary and medicinal species. The on‑site Altamont Plant Sales nursery, run by local gardener Robert Miller, sells a selection of the garden’s own cultivars – a wonderful souvenir for horticultural enthusiasts.
Seasonal Highlights
- Winter & Early Spring – Over 100 varieties of snowdrops carpet the woodland floor, creating a delicate white carpet that is one of the largest collections in Ireland.
- Spring – Bluebells, crocuses and early rhododendrons add colour to the shaded glades.
- Summer – The walled garden bursts with roses, lavender, lilies and foxgloves; the lake’s surface reflects the vibrant foliage.
- Autumn – Japanese maples, beech and oak turn fiery red and gold, while the river walk is alive with migrating birds and butterflies.
