Overview
Cavan Burren Park packs more than eighty archaeological monuments – Neolithic dolmens, Bronze Age wedge tombs, stone circles, rock art and stone walls that predate the bog now covering them – onto a single limestone plateau above Blacklion, and it costs nothing to walk. Coillte, which manages the forest, rates it one of the finest prehistoric relict landscapes in Ireland, in the same breath as the Burren in Clare it takes its name from.
If you only have an hour, walk to the Calf House Dolmen and the Giant’s Grave – two of the site’s headline tombs, reachable on the shorter loops from the visitor centre. Give it half a day and you can take in the rock art, the sinkholes where streams vanish underground, and the ‘Giant’s Leap’ gorge as well.
The interpretive centre, opened in May 2014, sets up the landscape with exhibitions on the geology, archaeology, mythology and folklore before you head out. It sits within the Cuilcagh Lakelands UNESCO Global Geopark, part of the wider Marble Arch Caves cross-border geopark.
A landscape carved by time
The bedrock formed around 340 million years ago, when a shallow tropical sea lay south of the equator over what is now west Cavan. Later uplift and the grinding of the last Ice Age, which retreated roughly 13,000 years ago, cut the karst you see today – limestone pavement, dolines and the huge glacial erratics dumped where the ice left them.
Neolithic people followed the retreating ice. About 5,000 years ago they raised the Calf House Dolmen, hauling massive stones into place as a communal burial monument. Later, between 2500 and 2000 BC, Bronze Age builders added the Tullygobbin Wedge Tomb, its trapezoidal chamber still showing two upright orthostats and broken capstones – a clear contrast with the earlier portal dolmen. Folklore layers over the archaeology: the ‘Giant’s Leap’ gorge takes its name from a tale of giants leaping the ravine.
Walking the trails
Five marked trails cover more than 10km between them, ranging from a short accessible loop near the centre to longer routes out across the open plateau. One is a multi-access trail suitable for wheelchairs and buggies; the rest cross uneven karst and moderate climbs and need proper footwear.
Whichever you pick, you pass glacial erratics and sinkholes that show what the ice did here, and short detours lead to viewpoints looking out over the Cuilcagh Mountains, Lough MacNean and the drumlin country beyond. The interpretive panels along the way are genuinely detailed – worth the extra few minutes at the dolmen, where they explain how the tomb was built.
Getting there
The park is just off the N16 Sligo–Enniskillen route, about 4km south of Blacklion on the Cavan–Fermanagh border. From Blacklion, take the N16 Sligo road and turn left just before you leave the village at the sign for Cavan Burren Park, then follow the signs for roughly 4km. It’s about 40 minutes from Cavan town, 40 minutes from Sligo and 20 minutes from Enniskillen. There’s no public transport to the gate, so you’ll need a car.

Nearby
- Shannon Pot – The mythical source of the River Shannon, a short drive off along the Cavan Way.
- Cuilcagh Boardwalk Trail – The ‘Stairway to Heaven’, the geopark’s best-known climb, north across the border in Fermanagh.
- Blacklion – The nearest village, home to the MacNean restaurant and a base for the surrounding walks.
Arrive early if you want parking near the centre, and set aside time at the Calf House Dolmen – the panels there explain the construction techniques better than almost anything else on the plateau.
