Plan Your Trip

Offering a coast-to-coast link through spectacular scenery in the heart of the Scottish Highlands, the Caledonian Canal is approximately 60 miles (96.5km) in length. 22 miles (35.4km) of this is man-made, with the remainder being formed by natural fresh water lochs.

Details of the various works can be found on our here

Dinghies and unpowered craft

If your boat is unpowered but too large or heavy to portage around the lock chambers then it will need to have a canal licence. For safety  occupants of small unpowered craft using the lock chambers are will be asked to disembark and pull the craft through on ropes. Boaters should note that for safety reasons, vessels must be rowed or under power at all times in the manmade reaches of the canal.

Speed Limit

The Bye Laws of the Caledonian Canal, which have been in force since 1966, require that vessels comply with the speed limits of 6 m.p.h. (5.2 knots) in any part of the canal where ‘the waterway has been raised artificially’ and Skippers are required to pass moored craft at ‘Dead Slow’. Please download our Large Craft Operating Protocol for full details.

Swing Bridges

Please be advised that other than for reasons of safety, the canal ROAD swing bridges will NOT be opened to boat traffic at specific times. Download the Swing Bridge Peak Time Restriction for details.


Vessels wishing to enter Clachnaharry Sea Lock should radio the Sea Lock Keeper on VHF Channel 74 or 16 as they pass under the Kessock Bridge. Radio Corpach Sea Lock as the Sea Lock comes in to sight. This allows the Lock Keepers to advise of any boat movements and prepare for your arrival.

Single Handed Passage

Vessels are required to have a crew member ashore to handle lines at lock flights. Passage by single handed boaters may be subject to delay as lock keepers may not always be available to assist. We therefore recommend single handed skippers make their own arrangements to ‘buddy’ with another vessel on transit to share rope handling, or arrange for crew to join the vessel for the duration of their canal trip.
