For setting the alarm for 4.45am on a Sunday morning! No really, there better had be.
Fortunately, there was. It was an exclusive tour to Stonehenge, Bath, Lacock and the Cotswolds courtesy of my friends over at Viator.
So here's Stonehenge. You need to be up early (or after closing hours) and book beforehand to get access to the stones (see English Heritage website for details). But it's worth it.
