The River Walk is a 2.5-mile (4 km) long footpath that follows the River Witham through the town of Grantham, Lincolnshire, England. It is a popular spot for walking, running, and cycling, and it offers stunning views of the river and the surrounding countryside.
The River Walk starts at the Grantham Marina and follows the river upstream to the town centre. It passes through a variety of different habitats, including woodland, meadows, and open fields. Along the way, there are a number of interesting features to see, such as the Grantham Watermill, the Rotunda Pumping Station, and the remains of the Roman town of Lindum Colonia.
The River Walk is open all year round, but it is best to avoid it during the winter months when the river can be flooded. The path is also not suitable for prams or wheelchairs.
