 The River Coln also joins the Thames at the canal junction, where there is sufficient room to wind a 70 ft narrowboat with care.There are no more locks upstream on the River Thames, with Lechlade normally considered to be the end of the navigable river, but there is a right of navigation as far as Cricklade, and small craft may be able to travel for a further three miles beyond Lechlade when there is plenty of water in the river.The Thames Path follows the remaining towpath along the southern bank past Lechlade to Inglesham.
