not good weather up here tomorrow, but Penrith towards ullswater follow that to kirkstone pass, over top of that turn right towards ambleside via struggle, to bottom turn right towards, rydal grasmere then thirlmere on towards derwent keswick and back towards Penrith.
that should cover from 06.30 to dusk at around 19.00, plenty to piccy following that route
hope that helps
