Overview
Castle Caldwell Forest Park covers 200 hectares of mixed broadleaf and coniferous woodland on a peninsula jutting into Lower Lough Erne. The site is defined by two main features: the striking ruins of a 17th-century Plantation castle and a network of well-marked forest trails that wind along the lakeshore. It’s a straightforward, free-entry destination that appeals to walkers, birdwatchers, and anyone interested in the layered history of County Fermanagh.
The forest management team is gradually replacing non-native conifers with native broadleaf species, slowly restoring the area to its ancient woodland character. This ongoing work, combined with the RSPB’s monitoring of the site as a bird sanctuary, makes it a quiet spot to observe nature without the crowds found at more commercial attractions.
History and the Belleek Connection
The castle itself was built between 1612 and 1619 by Sir Francis Blennerhasset. Designed as a fortified Plantation house, it featured a defensive bawn wall and two semi-circular flanker towers. By 1662, Enniskillen merchant James Caldwell had purchased the estate, renamed it, and began developing extensive gardens and fish ponds. The Caldwell family received a hereditary baronetcy in 1683, and the castle underwent Gothic-style renovations in the late 18th century.
The estate’s most unexpected legacy emerged in the 19th century. John Caldwell Bloomfield, an amateur mineralogist, commissioned a geological survey of the land in 1849. The survey uncovered rich deposits of feldspar, kaolin, flint, and shale. Bloomfield recognised their commercial value, partnered with industrialists Robert Williams Armstrong and David McBirney, and helped secure a railway spur to the nearby village of Belleek. Those raw materials directly enabled the founding of the Belleek Pottery factory in 1853, producing the fine white porcelain that would later gain international recognition.
The castle remained a private residence until the early 1900s, after which it was abandoned and left to decay. Today, the Northern Ireland Environment Agency and the Forest Service manage the ruins and surrounding woodland.
What to See
The estate is compact enough to explore on foot in a few hours, with several distinct points of interest scattered along the paths.
- Castle ruins – The main structure features crumbling battlements and the distinctive Gothic façade added in 1792. The stonework offers clear views of the lake and makes for straightforward photography.
- Caldwell Chapel & Graveyard – Located a short walk west of the castle, this rectangular stone chapel dates to around 1690. It retains a rounded-arch doorway and a buttressed east window. The surrounding low stone wall encloses a modest graveyard containing the remains of the Caldwell family and estate servants. The headstones are heavily weathered, and visitors are asked to walk carefully around the site.
- Railway Gate Lodge – Standing at the southern edge of the demesne, this castellated lodge was built around 1866 to control access along the railway embankment that served the pottery industry. The arched gateway and stone mullioned windows remain intact.
- Lime kiln & garden temple – Near the eastern tip of the peninsula, you’ll find an early-19th-century lime kiln used to process materials for the pottery. Further along, the ruins of an octagonal garden temple overlook the water.
- Fiddler’s Stone – Positioned at the main entrance, this local monument features a carved warning verse aimed at the travelling musicians of the past.
- Rossergole Point fort – The remains of a defensive fortification sit at the peninsula’s highest point, providing a clear vantage point over Lower Lough Erne.
Walking Trails
The forest offers three clearly marked loops, each graded as easy and colour-coded for navigation. All routes are detailed on OSNI Sheet 17 and marked with red, blue, and yellow arrows.
| Trail | Distance | Time | Grade | Wheelchair accessible | Dogs |
|---|---|---|---|---|---|
| Castle Scenic Walk | 0.5 mi / 1 km | 20 min | Easy | No | Must be kept under control |
| Beech Wood Walk | 1 mi / 1.5 km | 45 min | Easy | No | Must be kept under control |
| Rossergole Point Walk | 2.5 mi / 4 km | 1 h 20 min | Easy | No | Must be kept under control |
The paths traverse ash, beech, oak, and holly woodlands, passing through sections where the shoreline was lowered by roughly three metres in the 1880s. Spring brings bluebells, buttercups, and red clover to the forest floor, while autumn turns the canopy gold. The longer Rossergole Point route is particularly rewarding during these seasons.
Wildlife and Water Access
As part of the Lower Lough Erne Nature Reserve, the forest supports a steady population of waterbirds. Great crested grebes, tufted ducks, and reed buntings are common sightings, with the Common Scooter occasionally spotted near the reed beds. Pine martens and red squirrels have also been recorded in the deeper woodland sections.
A small jetty near the main car park provides a launch point for kayaks and paddleboards, and the designated picnic tables nearby make it easy to pause and watch the lake traffic. Fishing is permitted from the shore and jetty, subject to standard licensing rules.
Practical Information
Castle Caldwell Forest is open year-round with free entry. The main car park is located on Boa Island Road, Leggs, BT93 2AH. Facilities include public toilets, picnic tables, interpretation panels, and the jetty. Note that toilet access may be limited during winter months.
Getting there – The site is approximately five miles west of Belleek. From the A47, follow directional signs for the Castle Caldwell Forest car park. GPS coordinates: 54.4926358, -7.9736388.
Safety & Access – The trails are graded easy, but none are wheelchair accessible. Expect uneven forest tracks, roots, and occasional steps. The Rossergole Point walk occasionally passes through active forestry zones; temporary closures may occur for maintenance, so check for posted signage.
