A very low Derwent Reservoir... but a great walk!  We went straight up Win Hill from Heatherdene CP and then completed a circular of Ladybower with three very steep ascents.

This was with Peak District Walkers, a Meetup group, but there's quite a membership crossover between them and my Ramblers' group so I knew half a dozen or so.
