The River North Esk is a productive Scottish river flowing through Midlothian, known for its salmon, sea-trout, and brown trout fishing. The river offers excellent access throughout its length, though permits are required as the water is owned by various estates. A notable section flows through Dalkeith Country Park, providing a managed fly fishing environment. The river's character varies, with accessible beats divided by private access roads and sections suitable for both walking and vehicle access along the banks.
