The River Eden is a picturesque river in Cumbria, northwest England, flowing through the scenic Eden Valley. It rises in the Pennines near the border with North Yorkshire and flows northwest for approximately 90 miles (145 km) before emptying into the Solway Firth, an inlet of the Irish Sea. The river passes through the towns of Penrith and Carlisle, the county town of Cumbria, and its tranquil surroundings offer opportunities for walking, fishing, and boating.
