Overview
Two stone ringforts sit about 400 metres apart in a field above Cahersiveen, both free to walk into and both far quieter than anything on the main Ring of Kerry loop. Cahergall and Leacanabuaile were the fortified homes of early-medieval Kerry, a short stroll from the ruins of Ballycarbery Castle across the estuary. They give an uncluttered look at how Ireland’s landowners lived, farmed and defended their ground more than a thousand years ago.
Both are state-owned National Monuments managed by the Office of Public Works, free to enter and open year-round. There are no fences, ticket booths or guided tours, just drystone engineering against the backdrop of the estuary and the Skellig Coast. If you only have time for one, make it Cahergall for the walls, but the two stand so close together it makes little sense to skip either.
Cahergall: the chieftain’s stronghold
The larger of the two, Cahergall (from the Irish An Chathair Gheal, ‘the bright stone fort’), was built around the 7th century AD as a defended farmstead for a local chieftain. The site sits on a slight ridge backed by a low rock face, a natural advantage amplified by human engineering.
The rampart is a piece of dry-stone masonry that has largely held its shape. In places it rises up to about 6 metres high and stands roughly 5 metres thick at the base. Inside, the enclosure is ringed by concentric terraces and stepped sections, likely used for storage, livestock or workshops. At the centre lies the footprint of a large drystone hut with an internal diameter of over 6 metres, complete with a substantial hearth-pit. A rectangular annex built against the north inner wall hints at later changes as the settlement adapted over the centuries. From the top of the wall you get a clear view across to Ballycarbery Castle.
Leacanabuaile: the stone village
A few minutes’ walk away lies Leacanabuaile, a name that translates as ‘hillside of the summer pasturage’. Built later, around the 9th century AD, it served a slightly different purpose: still a defended homestead, but tied to seasonal farming. Its walls stand over 2 metres high and 3.3 metres thick, enclosing a space roughly 30 metres across, with the entrance facing east.
Inside, the domestic scale of early-medieval life is immediately clear. Three stone beehive houses (clochán) with corbelled roofs still stand, giving a tangible sense of the compact, insulated dwellings families and herders used. An underground passage, or souterrain, is visible at the entrance. These earth-sheltered tunnels stored grain, cheese or valuables, or served as a refuge during raids. The entrance can be inspected, but the passage itself is closed to the public for safety and preservation.
What the excavations revealed
Leacanabuaile was excavated in 1939–40, and the dig turned up the everyday clutter of a working farmstead: iron knives, bone combs and pins, millstones and lead items. Objects like these are what bring the bare stone circles to life, the tools of people who ground their own grain and defended their own gate.
Getting there & practical tips
By car: The forts are reached off the N70 at Cahersiveen. In the town, turn onto Bridge Street, cross the bridge, turn left at the crossroads and follow the signs along a narrow road. A small, free car park sits between the two forts, about 150 metres from Cahergall. It fills quickly in peak summer, so arrive early or come on a weekday.
By public transport or bike: The nearest bus stop is in Cahersiveen, about 3 km away. Services are limited, so most visitors drive, take a local taxi, or cycle the quiet country road. The walk from the town centre takes 30–40 minutes on a narrow but manageable road.
On-site facilities: There are none. No toilets, no café, no shop. The nearest amenities are in Cahersiveen. There is also no shelter on the exposed hillside, so bring a rain jacket even in summer; it can be windy up here in July.
Access & safety: The ground is uneven grass and stone, with some steps and slopes, so it is manageable for visitors with reasonable mobility but awkward for wheelchairs or strollers. Climbing the walls is prohibited for preservation reasons. Stay on the paths and keep clear of the outer edges when the wind picks up.
Ballycarbery Castle: The 15th-century tower house sits across the estuary, about 400 metres off. It stands on private land and is not open to the public, but the view of it from the forts is one of the best photographs on this stretch of the Ring of Kerry.

Time your visit for late afternoon: the low light picks out the terraces inside Cahergall and lights up Ballycarbery Castle across the water.
