Gairlochy lies at the southern end of Loch Lochy. An overflow from Loch Lochy was created here during the building of the locks on the Caledonian Canal. It was the diverted water plunging into the River Spean over artificial waterfalls that gave the hamlet its name – Gairlochy (the roar of the Lochy). The Mucomuir hydro-electric power station located beside the falls was built in 1960.

Gairlochy is a picturesque section of the canal where you will negotiate through 2 sets of lock gates on either end a wide basin where boats can tie up and berth. The lower lock gates are quite frequently left open, so you may only have to pass through one lock. The area has great views of Ben Nevis and an extensive beech forest provides delightful walking and cycling paths. 

Some of the smaller vessels, such as Eriskay and Mull of Kintyre, may be able to pass under the swing bridge, depending on the water level. However, DO NOT attempt to pass under the bridge without instruction from the lock keepers who also operate the bridge. Depending on traffic, this swing bridge is sometimes also left open and the lock keepers will advise accordingly.

Although Gairlochy itself consists of little more than a cluster of houses, it is situated approximately 3 miles from the village of Achnacarry in one direction, and 3 miles from the larger village of Spean Bridge in the other. Mooring, toilets, showers, laundry, litter/recycling and electrical hook up (Scottish Canals) are all available here.

After leaving Gairlochy you will travel along the final 5 miles canal section, passing through Moy Bridge and heading for the limit of cruising at Banavie.
