NB: You will need food for lunch as there are no convenient pubs or cafes. There's a Sainsbury’s at the start for a toilet break and to buy food. After a mile we pass Merton Abbey Mill where there are also toilets and a coffee shop. It’s all parks then, with no towns, until we reach Carshalton at the end of the walk. The train station is away from High Street.
