Course
The source of the river is on Warren Moor, part of Kildale Moor, just south of the village of Kildale. The river flows east until it reaches the Whitby to Middlesbrough railway line where it turns around to flow west to Kildale. It then flows south-south-west through woodland to its confluence with Dundale Beck where it turns north-west through Low Easby and Little Ayton, before turning west and then south-west at Great Ayton. It runs parallel to the A173 to Stokesley. The river becomes increasingly meandering as it continues south-west past Skutterskelfe to Hutton Rudby and Rudby, where it turns north-west and then west again over Slape Stones waterfall. At Crathorne it turns north and then north-east as far as Middleton-on-Leven before passing under the A19 in a north-west direction. The final couple of miles are north and north-west between Ingleby Barwick and Yarm, before the river joins the River Tees.

Geology
The river drains from the Cleveland Hills across a mixed geology of mostly Permian and Jurassic age bedrock of low permeability. Most of the deposits on top of the bedrock are boulder clay. There is mixed agriculture, with some moorland and forestry near the source.
Natural history
Since a weir on the lower river was built during the Industrial Revolution, migratory and territorial fish and mammals had been missing from the river. In 2007, the Environment Agency built a fish bypass at the weir. In 2011, they announced the return of spawning salmon for the first time in 150 years.
In 2020, it was confirmed that crayfish plague had infected the river after 40 dead white-clawed crayfish were found along a 700-metre (2,300 ft) stretch of river.
History
In Stokesley, the river is crossed by Taylorson's Bridge, a 17th-century packhorse bridge, which was once the only crossing in the town. The Domesday Book records a water mill on the banks of the river in the town. In Hutton Rudby, a plaque on a bridge marks the spot of a water mill that, amongst several uses, once made sailcloth.
