Overview
The white clay that made Belleek china world-famous was first spotted on this estate, on the walls of tenant cottages, and that discovery is the most interesting thing about a place that today reads as a quiet forest walk. Castle Caldwell Forest covers 200 hectares of mixed broadleaf and conifer on a peninsula reaching into Lower Lough Erne, built around two things: the ruins of a 17th-century Plantation castle and three waymarked trails along the lakeshore. Entry is free.
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 was built between 1612 and 1619 by Sir Francis Blennerhasset as a fortified Plantation house, with a defensive bawn wall and two semi-circular flanker towers. By 1662, Enniskillen merchant James Caldwell had bought the estate, renamed it, and set about developing gardens and fish ponds. The family received a hereditary baronetcy in 1683 and held the estate for roughly two centuries.
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 stayed a private residence until the early 1900s, after which it was abandoned. Today the Forest Service manages the ruins and the surrounding woodland.
What to See
The estate is compact enough to see on foot in a few hours, with several points of interest along the paths.
- Castle ruins – Dark, overgrown and unsafe to enter, so this is a look-from-outside affair. The stonework and lakeshore setting are the reason to walk out here.
- Caldwell Chapel and graveyard – A short walk west of the castle, a ruined rectangular stone chapel with a low wall enclosing a modest graveyard holding the Caldwell family and estate servants. The headstones are heavily weathered; walk carefully around the site.
- Lime kiln – An industrial-scale lime kiln survives on the peninsula, a reminder that this was a working estate, not just a big house.
- Fiddler’s Stone – At the main entrance, a copy of a gravestone carrying its warning inscription to travelling musicians.
- Rossergole Point fort – A defensive wall at the peninsula’s highest point, with a clear view 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 run through ash, beech, oak and holly, past stretches of shoreline that only exist because Lower Lough Erne was lowered by about three metres in the 1880s, exposing new ground now colonised by alder and willow. Spring brings buttercups to the forest floor and autumn turns the canopy gold; the longer Rossergole Point route is the one to pick in either season. If you only have twenty minutes, take the short Castle Scenic loop, which passes directly below the ruins.
Wildlife and Water Access
The forest is a bird sanctuary managed by the RSPB, and the Lower Lough Erne Nature Reserve borders its southern shore. The birds you’re likely to see are waders and terns of the lough – Sandwich tern, curlew, lapwing, redshank and common snipe – and red deer are reported in the woods.
A small jetty beside the main car park is a handy launch point for kayaks and paddleboards, or a spot for cruising visitors to tie up, with picnic tables nearby to watch the lake traffic.
Practical Information
Castle Caldwell Forest is open year-round with free entry. The main car park is on Boa Island Road, Leggs, BT93 2AH. Facilities are limited to car parking, a picnic area, interpretation panels and the jetty; there are no confirmed public toilets on site, so use Belleek before you come.
Getting there – The site is about five miles (8 km) west of Belleek, though some sources put it nearer four. From the A47 Belleek–Kesh road, follow 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.
Further reading – Detailed trail maps and geological background are available on the Cuilcagh Lakelands Geopark website. If you have time to explore the wider area, Castle Archdale Country Park, Tully Castle, and Lough Navar Forest are all within a six-mile radius.
