I assume you mean Arkengarthdale. Car park is S of Langthwaite on E side of road. Space for a dozen or more cars IIRC. Also seem to recall they wanted cash to use it but that may be a figment of an aging memory. The CB Inn up the hill N of the village on the right did good food and ale. You can park on the opposite side of the road to the CB for free. The Red Lion in the village itself, just across the beck is a character pub but the CB is better for food. Appropriately, the next hamlet up the lane is Booze.
