When I was growing up in Wembley, days out to places such as Kew Gardens, Hampton Court or Hampstead Heath were always by bus. It is a habit I have never lost and Nottingham is a great place to explore and discover the past by bus.
I plan to add published walks to my list as and when I find them. I have some of my own, but this is for another day. In the meantime, be amazed by just how much heritage you can reach by bus.
