The Home Valley Circular Walk is listed on the Long Distance Walkers Association website as follows:
"A walk along the heights around the Holme Valley, it takes in Castle Hill, the villages of Farnley Tyas, Thurstonland, Hepworth, Netherthong and Honley. There is a variety of scenery including many viewpoints." In particular the views of and from Castle Hill are spectacular. For much of the route you can see Emley Moor Transmitting Station (known locally as Emley mast), which is one of the tallest free-standing structures in Europe.
The Holme Valley is famous in the UK as the setting for the long running sitcom series Last of the Summer Wine. The route is almost all off-road, including a mixture of trails, field crossings and woodland paths. The occasional road sections are mostly on quiet country lanes with only one major road crossing near the finish. You'll pass four beautiful reservoirs on the high sections of the route.
The northern end of the route (start/finish) passes between a cluster of villages, whereas the southern section is more exposed on the high hills. Don't be fooled by the OS map which would give the impression the northern part is quite urban. In practice, even this section feels pretty rural as it takes paths through quiet woods and lanes.
Although there is a lot of climbing, there are also long sections that are relatively flat and runnable. However, even in summer there will be sections that are muddy so come prepared.
Walkers will be able to collect provisions in various pubs, cafes and shops along (or just off the route). It is also possible to run the route in a self-supported way.
