Get across to Caernarfon and do a tour of the big mountains of Wales, maybe get down a wee bit lower at a weekend (preferably).
Or
Get up to Dundee/Glenrothes/Perth, even the west side of the fine land and see some truly epic scenery. If scenery is what floats your boat.
No hassle with airspace either, mostly f or g up there. Might be a bit of a treck in a 152 or similar though without tanker support!
