As Midlifecrisis said – decent short outing
Or if you really want to go into Wasdale, then you can climb/push up through Miterdale, drop from Irton Fell to Nether Wasdale, head up and around the lake then climb south to Burnmoor Tarn. Then descend into Boot. The climb to the tarn is a bit wet and horrible, or it was last time I did it!
