Might go for a family walk around Grasmere, Rydal and up Loughrigg if the weather improves as forecast.
I still have memories of walking around Rydal from (ahem) 51 years ago - bracken covered slopes of Loughrigg above Rydal, tadpoles in a slate cavern, and an ascent of mighty Helm Crag, my first Lakeland fell (certainly seemed mighty to a 7 year old).
