For toilets, a good café, leaflets, booklets, post cards, farm shop garden centre - we recommend Wyatts (c. 1 mile east of the Rollright Stones towards Great Rollright). The nearest pubs and restaurants are the Greedy Goose at Chastleton and the Red Lion at Long Compton which also does bed and breakfast.
