Garelochhead is a small village at the north end of the Gare Loch in Argyll and Bute, Scotland, 7 miles (11 km) northwest of Helensburgh. Loch Lomond is a few miles to the east, and Loch Long to the west. Garelochhead's 1,265 residents (2001 census figure) are served by Garelochhead railway station on the West Highland Line and a local bus service running between Coulport and Helensburgh.
It is the nearest village to the HMNB Clyde naval base which houses the United Kingdom submarine fleet.
Garelochhead, originally in Dunbartonshire, developed from the 1820s with the advent of steamer cruising during the Glasgow Fair holiday. Tourism was boosted with the opening of the West Highland Railway line to Fort William in 1894, and in the late 20th century its prosperity was linked to the deepwater oil tanker terminal at Finnart on Loch Long and the Faslane naval base. Garelochhead Forest lies to the south.
In 1854 there was a great dispute that became known as the Battle of Garelochhead fought between the locals, led by Sir James Colquhoun, and the passengers of the steamer Ship "Emperor". The trouble started when Colquhoun did not want trippers on the sabbath day. The battle was eventually won by the passengers, but undeterred Colquhoun took his case to the courts who subsequently banned sailings on Sundays.
Before Faslane naval base was constructed during World War II, Garelochhead was a summer destination for people from Glasgow who would arrive from the Gare Loch and spend time in one of the Garelochhead hotels. Following transport advancements, holiday makers stopped coming to Garelochhead. Faslane was built after this, and extended the town as workers settled in the area.
During the 1990s, two of the villages hotels, The Dahlandui and Garelochhead Hotel, burnt down in fires allegedly started by their owners due to the falling tourist attraction of Garelochhead but mainly due to the loss of trade due to the winding up of the construction of Faslane Naval Base.
In the last ten years, due to lack of attendance the local Roman Catholic Chapel has closed down with the Church of Scotland Kirk in the village holding a combined congregation of both Protestant and Catholic
Garelochhead Training Camp is a military training facility located nearby.
