Overview
The Cavan Way is a 21.7 km (13.5 mi) linear walking trail that cuts through the heart of County Cavan’s lakelands. Recognised as a National Waymarked Trail, this moderate-grade route connects the riverside village of Dowra with the border settlement of Blacklion. Walkers follow a distinctive yellow arrow on a black background along a mix of quiet country roads, riverside paths, forest tracks, and open moorland. The trail is typically completed in a single day, though it can easily be split into two half-day walks. Please note that dogs are not permitted anywhere along the route to protect the local wildlife and livestock.
Route Sections & Navigation
The trail is commonly divided into two roughly equal sections, each around 13 km long. You can walk the entire route in one direction or tackle each half separately:
- Blacklion to Shannon Pot: Starting from the border village, the path climbs steadily into the hills, offering early views over Upper and Lower Lough MacNean. This section passes through the limestone karst of the Cavan Burren and culminates at the trail’s highest point, the Giant’s Grave passage tomb.
- Shannon Pot to Dowra: From the source of the river, the route descends gently through woodland and open bogland. It follows the banks of the young River Shannon for several kilometres before finishing at the historic village of Dowra.
Both sections share the same waymarking and are maintained under the Irish Government’s National Walks Scheme, which funds local landowners to keep the path clear, safe, and well-signposted.
Key Highlights
One of the trail’s primary draws is the Shannon Pot, a small, mystical spring traditionally regarded as the source of the River Shannon, Ireland’s longest river. Located roughly halfway along the route, the pot sits in a sheltered valley that feels worlds away from the surrounding open moorland.
As the path climbs into the northern Cuilcagh Mountains, the terrain shifts dramatically into the limestone landscape of the Cavan Burren. Here, walkers encounter exposed limestone pavements, sinkholes, and underground streams. The trail reaches its highest point at the Giant’s Grave, an ancient passage tomb perched at 260 metres (850 ft). From this vantage point, the views sweep across the lake system and the Cuilcagh range, making the steady ascent well worth the effort.
Further along the route, near the Moneygashel crossroads, you can spot the remains of a traditional stone sweat house, offering a tangible link to historic Irish rural life. The descent towards Blacklion passes through mixed woodland and heathland before finishing in the village, where the MacNean Resource Centre provides excellent context on the region’s geology and archaeology.
History & Heritage
Known in Irish as Slí an Cabhán, the trail was devised in the mid-1980s by local enthusiast Harold Johnston. It was officially established between 1984 and 1985 by the Blacklion Community Council and the Cavan County Development Team. Today, it is managed by Cavan County Council and serves as a crucial link in Ireland’s long-distance walking network.
The Cavan Way connects the Leitrim Way at Dowra with the Ulster Way at Blacklion. It also forms a key segment of the ambitious Beara-Breifne Way, a long-distance route under development that traces the historic 1602 march of Donal Cam O’Sullivan Beare from the Beara Peninsula in County Cork to the Kingdom of Breifne.
Geology & Wildlife
The trail lies within two protected designations: the Cuilcagh Lakelands UNESCO Global Geopark and the Marble Arch Caves Global Geopark. This dual status highlights the area’s exceptional karst geology. The Cavan Burren section is a relict landscape, hosting ancient flora that has survived since the last ice age.
Spring and early summer are particularly rewarding for nature lovers. The limestone pavement is often carpeted with wild thyme and heather, while sheltered hollows shelter wild orchids and bluebells. The upland heath supports a variety of wildlife, including Irish hares, badgers, and birds of prey such as buzzards. Grasshopper warblers and goldfinches are also common sightings along the wooded sections.

The Cavan Way is best tackled between late spring and early autumn when daylight hours are longer and the moorland is less likely to be waterlogged. The ground can be soft and muddy, especially near the Shannon Pot and on the open bogs, so sturdy waterproof hiking boots are essential. A small windproof layer is also advisable, as the exposed limestone uplands can be breezy even on mild days. Before setting out, download the official route maps to your phone, as mobile signal can be patchy in the valley sections near the Shannon Pot.
