A great boats trip service called Boyne Boats operatesd trips along the Oldbridge section of the Boyne Navigation. As of last summer, they extended their trips up on the River Boyne, near to Lock 3 (Lower Newgrange Lock).
They didn’t just offer a simply boat trip but step their passengers through 5,000 years of history from the area. Stories told would include the local legend of the Salmon of Knowledge.
Dates of available trip dates could be found on their website.
