Overview
Hag’s Leap rises 330 metres above the Glenade valley in County Leitrim, an isolated limestone stack split off the northern face of the Dartry Mountains and known locally as Tumpaunmore. Beneath its cliffs sits Poll na mBear – “the hole of the bears” – where excavators found the bones of brown bears that denned here thousands of years ago. It stands beside the adjoining Eagle’s Rock.
Set your expectations before you go: this is a roadside viewing point, not a destination you walk into. There’s a free car-park, a level platform and an interpretive board, and that is the whole visit – the cave is sealed and the land beyond the platform is private. What you’re here for is the view and the photograph, so come when the light is good rather than making a special detour in flat midday glare.
A glacier-carved limestone pillar
The rock that forms Hag’s Leap belongs to a Carboniferous limestone belt laid down around 300 million years ago, when this region was a shallow tropical sea. The massive pillar was carved out during the last Ice Age. As glaciers advanced and retreated, they gouged out the Glenade valley, while meltwater poured into fissures in the rock. The repeated freeze-thaw cycles widened these cracks until the structural support failed. A massive chunk of the north face of Tievebawn collapsed along a fault line, leaving the isolated, cone-shaped stack we see today.
Over millennia, slightly acidic rainwater has continued to dissolve the limestone, carving a network of inaccessible caves and fissures into the hilltop. This ongoing geological process has shaped not just the stack itself, but the rugged, serrated rock formations that guard the surrounding slopes.
Poll na mBear: the cave of bears
The most famous of the hilltop’s dissolved voids is Poll na mBear. Early excavations in the 2000s uncovered the skeletal remains of several brown bears and their cubs, dated to approximately 2000 BC. The discovery provided concrete evidence that Ireland’s uplands once supported thriving bear populations.
Humans first arrived in Ireland around 8000 BC, meaning early settlers would have shared this landscape with brown bears for thousands of years. The cave’s location high in the limestone karst suggests it served as a natural shelter or hibernation den, preserving the remains in the cool, dry conditions typical of Irish cave systems. Today, Poll na mBear is sealed off for conservation and safety, but its dark mouth remains clearly visible from the viewing platform, offering a tangible link to Ireland’s prehistoric wildlife.
Eagle’s Rock and the Cailleach’s garden
Just beyond Hag’s Leap lies Eagle’s Rock, an adjoining cliff face that historically provided nesting grounds for birds of prey. Golden eagles were once a common sight across the Irish uplands until they were hunted to extinction roughly a century ago. Today, visitors can spot buzzards and occasional raptors circling the thermal drafts, particularly in the early morning or late afternoon.
Local folklore offers a different explanation for the landscape’s dramatic features. According to legend, the Cailleach (the ancient winter goddess) shaped the area as the ice melted. She is said to have leapt from peak to peak, hurling massive boulders and carving valleys with storm-force winds. The isolated pillar of Hag’s Leap was fashioned as a perch where she could survey her domain. Some tales even mention her twin sister, Brigid, who helped design the lush green plains of the Glenade valley as winter receded into spring.
Practical Information
- Access & Parking: Free car-park located off the R280, just south of Glenade. The viewing platform is a short, level walk from the parking area, making it easily accessible for most visitors.
- Site Restrictions: This is a viewing point only. There is no public access for walking or hiking beyond the platform due to private land boundaries and steep, unstable terrain.
- Facilities: A bench and interpretive signage are provided on site. There are no toilet facilities, so plan accordingly.
- Best Times to Visit: Early morning or late afternoon offers the best lighting for photography and bird-watching. Summer provides clearer skies, while winter mist can add a dramatic, atmospheric backdrop to the limestone stack.
- Safety & Etiquette: Stay on marked paths and keep a safe distance from cliff edges. The surrounding slopes are private land; respect all signage and do not attempt to access the cave or upper trails.
- What to Bring: Windproof layers are essential, as the exposed hilltop can be cold and breezy year-round. Binoculars enhance the bird-watching experience, and mobile reception is limited, so download offline maps beforehand.
Nearby stops in north Leitrim
Because the stop itself is short, most people pair it with other sites along the R280:
- Glencar Waterfall – A dramatic cascade set within a forested valley, reachable via a short, well-maintained walk.
- Acres Lake – Boardwalk and Visitor Centre – A peaceful lakeside destination featuring a floating boardwalk and excellent wildlife spotting.
- Battlebridge – A riverside hub known for its historic stone bridge, camping facilities, and outdoor adventure activities.
- Cavan & Leitrim Railway – A heritage narrow-gauge railway offering scenic journeys through rolling countryside and historic stations.
- Scenic Drive Loop – Combine the R280, R282, and R281 for a leisurely circular drive with multiple pull-outs, passing through quiet townlands and ancient megalithic sites.
Plan your visit for a quiet weekday morning to secure the best parking spots and enjoy the valley without crowds. The interpretive board near the car park provides a helpful starting point for understanding the geology and bear discoveries before you step onto the platform.
