The Clay Way is an excellent 11.5 mile linear walk which stretches the length of the Forest of Marston Vale taking in spectacular views of the Vale, Greensand Ridge and other parts of Bedfordshire. The route mainly follows public bridleways and passes through the villages of Bromharn and Cranfield. The walk is situated on the clay soil of the West Bedfordshire Ridge. Paths can become very boggy during winter months.
