Overview
The Knockmealdown Mountains straddle Tipperary and Waterford, and the feature most people come for is a road. The Vee is a sharp, V-shaped pass carrying the old Lismore-to-Clogheen mail-coach route over the ridge, crossed today by the R668, with views towards the Golden Vale and down to Bay Lough. The range runs east to west along the border, a line of heather-covered sandstone summits with no visitor centre, no turnstile and no admission fee: open upland, a few lay-bys, and a lot of weather.
Stop only in a proper pull-in and choose a walking route before you set out. Knockmealdown itself rises to 794m, and Sugarloaf Hill (663m) is its near neighbour along the ridge.
The Vee and the drive
The Vee Scenic Drive runs between Lismore and Clogheen, and the climb to the pass is the part to linger over. From the viewpoint near the top you look out over the Golden Vale and across to the Galtee Mountains, with Clonmel, Cahir, Ardfinnan and Ballyporeen laid out below and, on a clear day, Cashel away to the north. Directly under the pass sits Bay Lough, a small dark corrie lake. In late spring and early summer the rhododendron that has colonised these slopes turns the roadsides solid purple for a few weeks – a genuine spectacle, even if the plant itself is an invasive headache for the people managing the hill.
Near the head of the pass is Grubb’s Grave, a stone cairn marking the resting place of Samuel Grubb, whose family had long ties to the land below. A little further into the hills lies the grave of Henry Eeles, an eccentric remembered as much in local story as in fact. St Declan’s Way, the waymarked pilgrim route revived between Cashel and Ardmore, crosses the range at the Vee, following much the same line as the centuries-old mail road.
One honest caveat: the road over the pass is narrow and twisting, and cars parked carelessly on the bends make the drive harder for everyone. Use a proper pull-in, and come on a weekday morning if you can.
Choose a walk
Knockmealdown Active lists a short there-and-back route down to Bay Lough. The return climbs back to the road. Stay on the path and keep back from the banks.
For higher ground, Dungarvan Tourism describes a 10 km Knockmealdown–Sugarloaf horseshoe with about 600 m of ascent. The descent from Sugarloaf is steep. Carry navigation equipment and allow time for the weather and terrain. In poor visibility, choose a lower route.
The mountain section of St Declan’s Way is graded strenuous. Parts use private land with the owners’ permission. Follow the current access notice and waymarks, and leave dogs at home for this route.
Underfoot and on the tops
The ground on the tops is rough heather and bog rather than built path. Walkers regularly describe the descents as boggy and slippery; the summits hold cloud, waymarkers are sparse, and mobile reception drops away once you leave the main valleys. From the top of Knockmealdown the view reaches Dungarvan and Youghal harbours and the River Blackwater; in very clear conditions you can pick out the high Kerry mountains far to the west.
Carry a map or an offline GPS track, bring waterproofs whatever the forecast, and don’t rely on the phone to navigate you off the hill in fog.
Wildlife
The heather slopes and boggy hollows are a designated breeding ground for two protected and declining birds, the red grouse and the hen harrier – both need a wide, quiet berth, particularly through the spring and early-summer nesting season. Birdwatchers also record cuckoo, nightjar, crossbill, buzzard and grasshopper warbler across the range through the year.
Heritage on the hill
In 2023 the volunteer group Knockmealdown Active, working with the Irish Uplands Forum and funded by the Heritage Council, completed a digital Heritage StoryMap of the range, gathering written histories, drone footage and mapping into one place. It’s a good thing to browse before a visit – the group also keeps trail updates and event news on its social media, worth a look for current ground conditions.
Getting there
The usual approach is from Clogheen in County Tipperary, climbing into the Vee on the R668. There is no visitor centre on the mountains, and nothing to rely on for water, food or bins, so bring your own and take all rubbish home. If you can only time one visit, aim for late spring when the rhododendron is out along the Vee and the longer evenings give you room to wait out the cloud on the tops.
