Extent of the park area

Clyde Muirshiel Regional Park is the collective name for areas of countryside set aside for conservation and recreation on the South Clyde estuary in Scotland.

The park covers an area of 280 km2 (110 sq mi) of Inverclyde, North Ayrshire and Renfrewshire, stretching from Greenock in the north, down the coast to Largs and West Kilbride and inland to Dalry and Lochwinnoch.

It consists of Castle Semple Loch and Collegiate Church, The Greenock Cut Centre (formerly Cornalees Bridge), Muirshiel Country Park, Barnbrock Farm, Lunderston Bay, Locherwood, Haylie Brae and Knockendon.

Muirshiel, a Scots language name, translates to "moorhut" in English.[2]


Originally a grouse shooting estate, a Regional Park designation for the area was first proposed in 1947. However it was 20 years later that Renfrewshire County Council proposed the Renfrewshire Regional Park and implemented a programme to manage an area of 30,000 acres (12,000 ha) including the creation of Muirshiel Country Park in June 1970. Castle Semple Water Park followed in 1971 and the Cornalees Bridge Visitor Centre opened in 1973. Responsibility for the parks was taken over by Strathclyde Regional Council in 1975 before the Clyde Muirshiel Park Authority came into existence in 1990. Today the Authority's committee comprises councillors from the three local authorities as well as Scottish Natural Heritage.

Facilities within the park[edit]

Lunderston Bay Beach and picnic area.

Two Country Parks with visitors centres are located within the regional park at Castle Semple Loch and Muirshiel, together with a separate visitors centre, the Cut Centre, at Cornalees Bridge, Loch Thom, to explain the Greenock Cut. An outdoor activity centre and boat and bike hire facilities are based at Castle Semple. Barnbrock hosts a campsite, and community woodlands are to be found at Locherwoods and Outerwards. The sandy beach at Lunderston Bay is connected by a shore walk along the coast to Inverkip. Loch Thom and the Greenock cut provide easy walks in a context of industrial history, and the Collegiate church and Castle Semple are of interest to historians of an earlier era. There are numerous other sites, such as the Haylie Brae, with car parking for visitors to enjoy picnics, good views, wildlife, walks and cycles, and wide opportunities for hillwalking.


Clyde Muirshiel offers year-round instructor led activities include sailing, kayaking, canoeing and raft building on the shallow inland Castle Semple Loch as well as land activities such as archery, mountain biking, hill walking, orienteering, navigation and first aid. Among the most popular hikes in the park can be remembered the Lochshore Loop, a 2 km (1.2 mi) walk from the visitor centre of Castle Semple, a trail leading to Windy Hill from the visitor centre of Muirshiel and a 10.5 km (6.5 mi) circular path from the Greenock Cut visitor centre.[3]

The Sustrans Cycle track[edit]

The Sustrans Lochwinnoch Loop Line cycle track runs through the Castle Semple Loch visitors centre. It is 14 miles (23 km) long and is part of the Lochs and Glens Route. It follows the National Cycle Route 75 from Paisley Canal Railway Station to Johnstone and then heads southwest to Kilbarchan, Lochwinnoch and Kilbirnie passing Castle Semple, Barr and Kilbirnie Lochs. Being mainly built on an old railway line it has easy gradients and is mostly traffic free.

Sports Clubs at the Loch[edit]

The Loch is the home of the following clubs; Castle Semple Sailing Club (founded 1966), Castle Semple Rowing Club and Clyde Windsurfing Club.

Historic sites[edit]

The Castle Semple Collegiate church[edit]

Castle Semple from the 'Temple' hill.

This Church was founded and endowed ; it stands near where the original Castle Semple once stood. Castle Semple was a Collegiate church, which means that it was administered and served by a college of canons or prebendaries, presided over by a dean or provost. Collegiate churches were often supported by lands held by the church, endowed here in 1504 by John, 1st Lord Sempill. The church is built in a late Gothic style with a rectangular body and square tower at the west end and a three sided apse at the east end. The Church is in the care of Historic Scotland.

The Castle Semple Temple[edit]

Memorial to the MacDowalls of Garthland, latter day owners of the Castle Semple estate.
The Castle Semple temple.

The small temple building or folly on the Kenmure Hill knoll to the northern end of Castle Semple loch is one of the few remains of the Castle Semple estate. Col. William MacDowell was responsible for the 'Temple' and also for building of Castle Semple House, which was destroyed by fire in 1935. All that remains of this 900-acre (360 ha) estate is the folly, a walled garden and a pair of gate arches.

Loch Thom and the Greenock cut[edit]

Looking back along The Cut from Overton.

A freshwater loch known as Shaws Water used to exist at a level high above Greenock until the civil engineer Robert Thom prepared a scheme to turn this into a reservoir, subsequently named after him as Loch Thom. He also created the aqueduct which became known as "The Cut", the whole scheme officially opening on 16 April 1827. The aqueduct supplied both a dependable flow and a good quality of water to the town for both domestic and business purposes.

Leaving Loch Thom at Cornalees, The Cut, with its footpath, runs westward and then turns northward as it follows the contour of Dunrod Hill which it follows round until running directly above the town of Greenock at Overton, having come a distance of 5 12 miles (9 km). It collects some of the water from streams that cross its path, and a series of sluice gates incorporate an ingenious automatic way of releasing surplus water.[4]

Muirshiel Barytes Mine[edit]

Seams of Baryte minerals were found in three gullies about 2 kilometres (1.2 mi) north of Hill of Stake, cut into the slope by tributaries of the River Calder, Renfrewshire. Small-scale open cast mining of the baryte began around the mid 18th century, with horizontal tunnels or adits cut to follow the seams of the mineral. Between 1859 and 1920, production was 17,678 long tons (17,962 t). A track was formed running around 4 kilometres (2.5 mi) downhill to a grinding mill sited on the River Calder, where the mineral was dressed or processed. Stables and houses for the workers were built adjacent to the mill, and a bridge crossing the river connected by a lane down to Lochwinnoch. By about 1918 the mine was run by the Muirshiels Mineral Co. of Lochwinnoch, but production ceased in 1920.[5]

Keir and Cawder Ltd. and James Millar Son and Co. Ltd. reopened the mine in 1942. They formed the Muirshiel Barytes Co. in 1947, and constructed new shafts to depths between 64 metres (210 ft) and 64 metres (210 ft). This gave access to veins of baryte of a finer quality, which was taken directly to a dressing plant in Glasgow. Production was 1,580 long tons (1,610 t) in 1944, rising to 16,987 long tons (17,260 t) in 1949. Up to this stage there was no electricity at the mine, and minerals were transported in wagons on rails, moved to the surface by human or horse power. The workforce came from Lochwinnoch and Kilbirnie. In 1960 the mine was taken over by Anglo Austral Mines Ltd., and electrical power was introduced to power winding gear for the wagons and lift them to the surface, where the barytes was loaded into lorries. In 1962 Rio Tinto Zinc became the operator. A new dressing plant was constructed just downhill from the mine, to process output from a lower quality vein. At this time up to 48 people from Lochwinnoch and Kilbirnie worked at the mine, including 11 skilled miners, each with an assistant, as well as maintenance and surface workers. Annual production reached a peak of 16,987 long tons (17,260 t) in 1964. Production ended on 5 September 1969.[5]

When the country park was formed, the Muirshiel Visitor Centre was built a short distance downhill from the pre-1920 site of the mine. The original workings and bridge over the river have fallen into ruin, the track over a new bridge constructed nearby in the 1960s gives access for walkers. Part of the site is used for off-road vehicle driving instruction. At the mine itself, a seismometer transmits measurements by radio to the British Geological Survey [5]
