Recreational use

The river is occasionally used for recreational purposes, such as

kayak A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word ''qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each se ...

ing. This is usually limited to periods after heavy rainfall when the river is in spate, because in times of normal flows the river is too shallow to use. When the river is in spate it becomes very technical, with many weirs and holes. The river is quite narrow and relatively shallow, making the rocky bed hazardous for kayakers who capsize. By far the most challenging part is in the higher-volume upper section of the river, where a small tributary of the Ashop flows swiftly through a steep tunnel under the road. The river has many obstacles such as fallen trees, and fences which lie across the channel and must be negotiated. This makes it dangerous at times of high water if the river is flowing rapidly.
