The church is a good place to park for your boogie round Bell Hill, except on a Sunday when other places in the village should be used. One advantage of starting at Underbarrow is that on your return you could sample the delights of the Punchbowl!
A short way north of the church, past some houses, and Chapel Lane runs off to the NE. It is a narrow and stony lane with high banks but is easily traversed, except with a pushchair! Reaching the open fields and livestock may be encountered. The GPS will lead you to an obvious object. From the shell of the old, the new springs forth. Beware sometimes the track is not mainained and can be overgrown.
Or park in the north and follow the easy to find footpaths south
