I've been through Arnold several times, either on the Calverton Connection or whenever I've gone up there while exploring bus routes. Today, however, I spent some time there walking.
Not particularly far, mind you; I mostly walked along the route the Calverton Connection takes. What surprised me about Arnold is how hilly it really is; I suppose I shouldn't have been, given that Calverton and nearby Gedling village are also mountainous by Nottingham standards. Clifton is flat by comparison!
Arnold is a part of Nottingham that is worth exploring some more.
