Navigating the Royal Canal

The Royal Canal main line is 146 km with 46 sets of locks. The Longford Branch (presently dry) runs from the main line at Killashee to the town of Longford and is 8 km long. All the locks on the Royal Canal are manually operated. Passage through the locks is only permitted during daylight hours. Contact the waterway controllers for lock operations.

Speed Limit:  the max speed limit is 6km/h. Please ensure your wash and wake does not cause nuisance to other waterway users, especially in confined waters or channels. Reduce speed where necessary to prevent bank erosion, damage to reed beds and destruction of birds’ nests among reed and bank habitats. Slow down where boats are moored, when approaching quays, jetties or locks or where water activities are taking place.

Mooring Time Limits: No boat shall be moored at the same place on the canal or within 500 metres of the same place, for more than 5 days without the appropriate permit.

Fuel Points: Fuel is available from garages adjacent to the canal

Maintenance works: Maintenance work on the system is whenever possible carried out during the winter months. However, it is always advisable to contact Waterways Ireland before making any journey, to confirm that the section of waterway that you wish to navigate is open.
