Overview
Divis Hill (Irish: Dubhais, “black ridge”) dominates the north‑west skyline of Belfast at 1,568 ft (478 m), making it the highest point in the Belfast Hills. Together with the adjoining Black Mountain it forms a 1,500‑acre mosaic of upland heath, blanket bog and basaltic ridges that stretches across the Antrim Plateau. The summit is marked by a trig point, the Divis transmitting station and a historic stone‑pitched path. Since the National Trust took over the former Ministry of Defence training grounds in 2004, the hill has been open year‑round, free of charge, and is now billed as Belfast’s largest urban green space.
History & Background
The name Dubhais reflects the dark basaltic bedrock that caps the hill. Archaeological surveys have uncovered Bronze‑Age hut circles, ringforts and field systems, testifying to millennia of human activity. In the 20th century the site served as a rifle range and, from 1953 to 1999, a Ministry of Defence training area and communications site.
After the National Trust’s acquisition in 2004, the estate was restored – paths were rebuilt, debris cleared and a floating boardwalk installed to reach the summit. The boardwalk uses stone sourced from County Clare, a detail highlighted on the Trust’s site. The project won the Amazing Spaces award in 2005. In September 2023 the National Lottery Heritage Fund granted £3 million for the “Divis – A View to the Future” scheme, aimed at expanding trails, improving habitats and cementing the hill’s status as Belfast’s premier urban green corridor.
A stone cairn near Armstrongs Hill is recorded as Carn Sheaain Bhuidhe (Yellow John’s Cairn) on OS maps, linking the hill to local folklore. The original trig pillar was removed in the early 1970s to make way for the masts; it now resides outside the OSNI headquarters on Stranmillis Road, with plans to relocate it back to the summit.
What to See & Do
Walking Trails
| Trail | Distance | Difficulty | Highlights |
|---|---|---|---|
| Summit Trail | 3 mi (4.8 km) | Intermediate / Challenging | Stone‑pitched ascent, trig point, 180° city and mountain panoramas |
| Ridge Trail | 4.2 mi (6.7 km) | Moderate | Boardwalk sections, transmitter masts, views towards the Antrim Plateau and Causeway Coast |
| Lough Trail | 0.9 mi (1.5 km) | Easy (all‑ability) | Flat, low‑contour walk, ideal for families; starts opposite the Long Barn |

- Summit Trail begins at the Divis Barn car park (OSNI grid ref J272744). The route follows the Tipperary Road, passes a small pond and a kissing gate before reaching the trig pillar at 475 m. On a clear day walkers can spot Belfast Lough, Lough Neagh, the Mourne Mountains, the Sperrin range and, far beyond, Scotland, the Isle of Man and even the peaks of Donegal.
- Ridge Trail continues from the summit down towards Black Mountain, crossing the iconic transmitter masts and offering additional viewpoints toward the Antrim Plateau and the Causeway Coast.
- Lough Trail provides a gentle, accessible loop suitable for strollers and wheelchairs, giving a quick taste of the hill’s heathland and pond habitats.
- Wildlife: Free‑range cattle graze the uplands from April to November, and the varied habitats support birds such as skylarks, meadow pipits, buzzards and occasional kestrels.
Events & Activities
- Doggy Ranger Day – a family‑friendly event where volunteers teach owners how to manage dogs on the hill while protecting wildlife.
- Rivers of Divis – Guided Walk – a seasonal walk exploring the historic rivers that shape the Belfast landscape.
- Adopt a Plot – visitors can sponsor a small area of heath to help with habitat restoration (details on the National Trust page).
- Volunteer Sessions – the Trust runs regular volunteer days for path maintenance, litter picking and wildlife monitoring.
Flora & Fauna
The upland heath is dominated by heather, gorse and bilberry, creating a colourful carpet in late summer. The blanket bog supports sphagnum mosses and a range of specialised insects. Birdwatchers may also spot the occasional buzzard or kestrel soaring on thermals above the ridge.
