I rented a bike from Inverness Bike Hire and followed a map that they gave me from Inverness to Loch Ness. It was a rainy and windy morning but I charged on. Once I got away from the city and onto the small quiet farm roads it was a very nice ride.
The first village upon arriving at Loch Ness is Dores and I stopped for a coffee at the Dores Inn. At Dores I turned around and followed an off road trail that is right next to the lake and river. The trail goes through an estate and near a castle but there was a big detour due to construction. At Scaniport the trail rejoins the main road and there is a turnoff to get on to the back road. The back roads are marked with the Bike Route 78 signs so it was easy to follow.
Once I crossed the big bridge over the Ness River on the edge of Inverness I turned south and went all the way back down the Caledonia Canal to the end. At the Dochgarroch Locks I crossed the canal and then returned on the other side. The trail goes all the way to Inverness.
In all the ride was about 40 km and took about six hours. It had a little of everything and was an excellent day trip from Inverness.
