AT A GLANCE
Why go?
Slievemweel is a name that tells you exactly what you are looking at. From the Irish An Sliabh Maol — the bald mountain — it is a low, open heathland hill in the southern Wicklow uplands, stripped of trees and scrub to bare heather and grass by centuries of grazing and fire. It does not shout. There is no trailhead with a car park, no signpost with distances, no summit cairn. What it offers is something rarer in a county that has become one of Ireland's busiest walking playgrounds: silence, open sky, and the feeling that you have wandered onto a landscape still working out what it is becoming.↗↗↗
At 578 acres, Slievemweel is a commonage — shared hill pasture that has been grazed by sheep for generations. A 2020 ecological survey mapped its habitats as a patchwork of dry heath, wet heath along two watercourses, acid grassland, and patches of dense bracken and gorse. You will walk among purple ling heather, hare's tail cotton grass, and the occasional bilberry shrub. Where the survey noted the hill was recovering from years of uncontrolled burning, small stands of native broadleaf are now being planted along the gullies, so the landscape is in transition from bare to green.↗
What you will see on the hill
Slievemweel sits in the Ballinacor South barony, bordered by townlands like Askanagap to the east and Corndog to the south. It is part of the wider Wicklow Uplands area, a vast expanse of commonage between the better-known peaks to the north and the lowland farming villages below. The hill itself is a ridge with slopes falling to both sides, its highest ground exposed and windswept, its lower ground damp where watercourses cut shallow gullies.↗↗
In late summer the heath turns violet and the grassland takes on a golden tone. In spring the gorse blooms bright yellow along the edges, and the new planting along the watercourses will show small bright green leaves against the grey slate-stone ground. The view is not a single panorama but a rolling sweep across other commonage hills — Slieveroe, Askakeagh, Ballymaghroe — each bald, each quiet, each carrying its own sheep.↗↗
What makes it special
The Irish name An Sliabh Maol means 'bald mountain' and the landscape bears it out — open, treeless, wind-scoured heath↗
Part of the Wicklow Uplands commonage network, where ecological restoration is actively transforming a landscape scarred by decades of uncontrolled burning↗
A genuine off-the-map spot: no waymarks, no facilities, no crowds — just hill, sky, and the sound of your own footsteps on heather↗
A little planning goes a long way
- Slievemweel has no dedicated trailhead or parking area. Approach from local roads in the Ballinacor South area near Askanagap or Moyne; park considerately at the roadside and be aware of livestock.↗
- The ground is rough, boggy in places, and the ridge can be exposed to wind. Waterproof boots and navigation skills are essential. There are no painted waymarks — map and compass or GPS recommended.↗
- The best seasons to walk are late May through early autumn, when the heather is flowering and days are long. Winter visits require checking local conditions and avoiding periods of deep standing water.↗
- This is working commonage. Keep dogs on leads around sheep and follow any instructions from graziers on the hill. The ecological restoration means new planting areas should be kept clear of foot traffic.↗
