The River Stinchar runs through the valley and the Colmonell area boasts three ruined castles: Craigneil Castle (thirteenth century), Kirkhill Castle (sixteenth century) and Knockdolian Castle (sixteenth century).
With a small population, Colmonell is a close community. The village has an annual Church Fete in August and an agricultural show the same month. In June there is the annual gala day, or "Fun Day", which is run by the Community Association. This has been extended in recent years to become a "Fun Week" during which a range of activities are arranged for the local community.
