The biggest hill:
The Wrekin is a hunk of volcanic material that jutts out of the North Shropshire plain. It isn't and wasn't a volcano, it's volcanic rock moved here by the mystery of time.
It is a very pronounced geological feature, so much so that it spun a number of legends. The main one involves an unhappy giant. The giant was on his way to Shrewsbury with a huge shovel of earth to block the River Severn. He met a cobbler and asked how much further it was. The cobbler cottened on the the giant's evil intent and said he'd worn out a whole bag of shoes walking from Shewsbury. The giant gave up and dumped the shovelfull of earth, creating the Wrekin. He scraped the mud off his boots and created the smaller Ercall. He then took the shovel and stuck it in the Wrekin, creating the Neddle's Eye, a huge cleft in the Rock.
The giant gave up, went home and Shewsbury was saved.
The other legend involves a small natural bowl in a large rock outcrop. It's known as the Raven's Bowl, legend has it that if the bowl is dry the Wrekin will fall down. Given the English climate you might think the Wrekin is safe, but I've seen it dry a few times.
The Wrekin is a splendid walk, about an hour for spectacular views, legends, geology and even ice cream on the way down at the Half Way House.
The Wrekin is the biggest hill you can climb in England, it is about 1,400 feet high, anything over 1,500 feet is a mountain, so this is pretty much the biggest hill there is.
