In reply to Lee E:
Lots of easy to moderates in the Grasmere area - get there early though as it's a honeypot.
Easedale Tarn - nice on a fine day for a picnic beside the tarn. Likewise Alcock Tarn. Or Helm Crag, nice little summit with a small scramble to reach the true summit, often not visited by walkers but fun if the rock is dry.
Grisedale Tarn from Dunmail Raise. In Langdale Stickle Tarn, nice but rather busy.
Also popular the tearoom up at Watendlath reached from various spots in Borrowdale (Great wood car park or Rosthwaite (shorter but steeper up/down though always a straightforward path.) Up there the birds flit around on to the table quite entertainingly.
