Day trip by rail to Matlock or Matlock Bath from Derby is also worth considering. Lovely scenery en route and when you arrive at destination, along with seaside resort type attractions, riverside locations/boat hire options and cable car trip across the stunning Derwent gorge at Matlock Bath that takes you up to Gullivers Land theme park, some or all of which may appeal to a 12 year old. There is also the Peak Rail heritage railway at Matlock that runs north in the direction of Rowsley.
