Just a quick and useful post. We recently purchased a joint pass to all the sites under the British Heritage Trust. All the information can be found here. It includes many places you can visit for free or half price. Stonehenge is one of them too. So far we visited two places in the "neighborhood":
Kenilworth Castle & Elizabethan Garden and Rushton Triangular Lodge. Kenilworth Castle is one of the premium sights. And indeed it looks premium and grandiose.
