It sounds like a fun day with very diverse surroundings and sites to see ! Nice report Tim made me chuckle.
Rich, there are a few in the Peak District, The Goyt being one and is supposed to be interesting on the right level but due to the terrain a lot of the water runs away quickly or if very wet they become risky. The river Noe in the Edale valley is another one which sounds a reasonable little paddle with some interesting features.
