The river Eachaig flows from Lock Eck to the Holy Loch passing the Cot House, Kilmun. Built in 1885, the Eachaig bridge is a listed building. This wetland is a habitat for many sea birds. You may spot kingfishers, sand martins, dippers, waders, geese, wading birds and mallards along the sand banks. There have even been sightings of osprey, sea eagles and otters. Sea trout, salmon and grey mullet are among the fish species in the river.
