Dumbarton is the second largest town in West Dunbartonshire and was formerly the centre of the Ancient Kingdom of Strathclyde. It lies on the north bank of the River Clyde and beside the powerful River Leven. Its outstanding attraction is Dumbarton Castle which sits on top of volcanic rock overlooking the Clyde Estuary and is one of the oldest fortified sites in Britain with a history dating back 1500 years. This 4* visitor attraction has at one time served as a Roman outpost, dark age citadel, medieval castle, garrison fortress and more recently as a military base during World War 2.

Dumbarton also offers you the chance to visit the Scottish Maritime Museum's Denny Tank which displays the fully restored Denny experimental water tank. This Victorian masterpiece is as long as a football pitch and was built in 1882 for testing ship designs. The 3* visitor attraction looks back on the glorious early days of the Clyde Shipbuilding industry.
