Overview

Lough Erne
Tourism Ireland

Lough Erne, straddling County Fermanagh, is dotted with islands that each tell a different chapter of Irish history. Boa Island (home to Dreenan), Lustymore Island, White Island and Inishmacsaint lie within the lake’s tranquil waters, offering a blend of striking stone monuments, ruined castles, early‑medieval monastic sites and unspoilt natural scenery. Whether arriving by ferry from Castle Archdale Country Park or by private boat from Enniskillen, visitors find quiet woodlands, panoramic lake views and a palpable sense of the past.

History & Background

  • Boa Island – Dreenan (Janus Figure): The twin‑faced stone, first recorded in 1841, stands 1.2 m tall and is carved from local sandstone. Early scholars linked it to the Roman god Janus, but most archaeologists now view it as a pre‑Christian Iron Age idol, possibly representing the war goddess Badhbh (the island’s namesake, Inis Badhbha). Its two faces may have symbolised dual aspects of a deity or a ritual mask.
  • Lustymore Man: A companion figure of similar style, discovered in a disused Christian graveyard on Lustymore Island and now displayed in Caldragh Cemetery. Both statues suggest a regional sculptural tradition that predates Christianity.
  • Ulster Plantation Era: The 17th‑century Castle Caldwell, built by Francis Blennerhasett of Norfolk, stands in a forest park on the banks of Lower Lough Erne. Though now a ruin, it marks the plantation’s imprint on the landscape.
  • Inishmacsaint: This small island hosts the remains of an early monastic settlement founded around 530 AD by St Ninnidh, grandson of High King Laoghaire. A 12th‑century stone church and an impressive high cross survive; the cross is richly carved with interlace, a bishop’s mitre and a possible depiction of the crucifixion, indicating its importance as a pilgrimage site.
  • White Island: Situated in Upper Lough Erne, White Island has no permanent buildings but gained a visitor profile after World II when the nearby Castle Archdale estate, once a flying‑boat base, was converted into a country park. A short ferry ride now brings guests to the island’s scenic walking trail.

Walking Routes & Activities

  • Boa Island Loop – A 3 km marked trail circles the island, passing the Janus stone, the Lustymore Man (via a short footbridge to Caldragh Cemetery), and several small lakeside viewpoints. The path is mostly level and suitable for families and casual walkers.
  • White Island Perimeter Walk – A well‑maintained 2 km loop offers uninterrupted lake vistas, with interpretive panels describing the island’s post‑war history. The route is flat and wheelchair‑friendly where the surface is compacted gravel.
  • Inishmacsaint Exploration – A short, self‑guided walk leads from the landing point to the stone church, high cross and a modest graveyard. The terrain is uneven in places; sturdy shoes are recommended.
  • Cycling – The forest park surrounding Castle Caldwell provides gentle, traffic‑free cycling routes that connect to the Boa Island ferry slip‑way.
  • Wildlife Watching – The islands support a variety of birds, including mute swans, whooper swans, ospreys and occasional kingfishers. Reed beds around the islands are prime for quiet bird‑watching, especially in early morning.

Practical Information

  • Getting There:
    • Boa & Lustymore Islands: Accessible by private boat from Enniskillen or by arranging a water‑taxi from the mainland. Local operators such as Erne Water Taxi provide on‑demand service; check their website for current rates and booking details.

    • Inishmacsaint: Reachable via a short private boat ride from the A46 car‑park or by water‑taxi arranged in Enniskillen.
  • Facilities:
    • No permanent amenities exist on the islands themselves; bring water, snacks and sturdy footwear.
    • Castle Archdale Country Park offers ample parking, a visitor centre, museum, restrooms and a café. The park’s car‑park is the main launch point for the White Island ferry.
    • Caldragh Cemetery provides a sheltered area and benches near the Lustymore Man.
  • Accessibility:
    • The White Island loop is largely wheelchair‑friendly; Boa Island’s trail includes some uneven sections but is manageable for confident walkers with mobility aids.

    • Early mornings are ideal for bird‑watching and avoiding the occasional summer crowds.
  • Safety Tips:
    • Weather on Lough Erne can change quickly; carry a waterproof jacket and check forecasts before setting out.
    • Tides are modest but still affect landing points; plan arrivals and departures with local boat operators.
  • Entry:
    • All islands are free to access; Inishmacsaint is a State Care Monument, and the other sites are on public or privately‑managed land.
  • Dog Friendly:
    • Dogs are permitted on the islands and on most walking routes, but keep them on a leash during the bird‑watching season to protect nesting wildlife.

Enjoy a day – or a leisurely weekend – hopping between Lough Erne’s historic islands, where ancient stone faces, monastic silence and serene lake scenery await.
