Edale is a small village located in the Peak District.
The easiest and quickest way is by train. Edale Station is located on the Hope Valley Line from Sheffield to Manchester Piccadilly, with direct trains every hour in each direction. There is usually one train an hour in each direction (although be sure of this before setting off), the journey time from Sheffield is 33 minutes and from Manchester, 43 minutes.
There is a small cafe next to the train station that sells snacks, sandwiches and drinks. The post office in the village also sells a variety of snacks and drinks, as well as all the other items you'd expect to find in a small convenience store.
