Are they free to visit without a stonehenge ticket?
We are planning to do the walk the free public path north of stonehenge and will either park near Larkhill (free parking, shorter walk) or at the Visitor Centre (paid, slightly longer walk). If we can visit the neolithic houses outside the visitors centre for free, that would sway me toward the latter.
I'm fairly sure the exhibition rooms at the visitor centre and not free and the shuttle bus from the visitor centre is not free. I assume you can walk for free from the visitor centre to the public path for free as well (i.e. they check the tickets near where you get off the bus, not near the visitor centre)?
