I presume you have a guide?
If so, check out Caseg Fraith and the undescribed easier area just above it. Plenty of easier stuff to go at, some classics on the lower tier and no unexploded weaponery lying around in the grass.
Otherwise, the ever popular RAC boulders has all of the above and may not be quite so ludicrously hot if there is a breeze. Or you could try the Caseg Boulders but they aren't quite so child friendly, neither is there so much to do.
