Ross Island

Ross Island is a wooded peninsula that extends into Lough Leane, at the heart of Killarney National Park in County Kerry. Once a copper mining zone, it now shelters the ruins of Ross Castle and nineteenth-century industrial remains, all wrapped in a forest of oak and strawberry trees. It's one of the most accessible and historically richest entry points to the park.

What you'll see

The peninsula concentrates several distinct attractions. The ruins of Ross Castle (15th century), a fortified tower of the O'Donoghue clan, overlook the lakeshore. The old copper mines, worked as far back as the Bronze Age and reopened on a large scale in the 19th century, leave behind galleries and stone buildings visible along the trail. The forest blends sessile oaks, ash trees, and strawberry trees—that rare Irish arbutus growing here near the northern edge of its natural range.

History and context

Copper from Ross Island has been extracted since at least 2,400 BC, making it one of western Europe's oldest mining sites. Archaeological research has established that this copper contributed to Early Bronze Age bronze production in Ireland. Mining resumed on a large scale in the early 19th century before stopping definitively. The castle, meanwhile, was the last Gaelic stronghold to resist Cromwell in Munster, falling in 1652.

Highlights of the visit

Ross Castle

The lakeshore tower offers a striking photographic backdrop, with Lough Leane in the background and the MacGillycuddy's Reeks mountains in the distance. Interior access is not always available; the exterior and moat remain freely accessible.

The copper mines

The mine trail runs past old shafts and ore-processing buildings. Interpretive panels trace the industrial and prehistoric history of the site. It's a short but enlightening detour from the main path.

The strawberry tree forest

Arbutus unedo, or strawberry tree, grows naturally here—a rare phenomenon in Ireland, linked to Kerry's mild microclimate. In autumn, its red fruits and white flowers coexist on the same shrub.

Lake views

Several clearings and rocky promontories open onto Lough Leane and its islands. On clear days, the park's peaks frame the horizon to the south and west.

Photography tips

Low morning light raking across the lake and castle is most favorable. In autumn, forest colors are particularly striking. From rocks along the water's edge, a low angle captures the castle's reflection in the lake. No known photography restrictions on site.

Location and access

Ross Island lies within Killarney National Park, approximately 2 km southwest of Killarney's town center. The walking path from Knockreer Gardens is the most direct route. Traditional horse-drawn carts (jaunting cars) also offer service from town. There is no parking on the island itself; the main park car park is located near Knockreer House. Accessibility for visitors with limited mobility is restricted on unpaved forest trails.
