Malcolm Webster, of Guildford, Surrey, denies murdering first wife Claire Morris by drugging her, crashing their car and setting it on fire in 1994.
He also denies attempting to murder his second wife in New Zealand in 1999.
The judge, jury, accused and legal teams travelled from the High Court in Glasgow for Tuesday's visit.
Jurors were given permission to leave the road and take a closer look down an embankment, at the exact spot where Ms Morris died.
They were at the scene of the crash - a section of the Auchenhuive to Tarves road at Kingoodie - for 12 minutes before leaving to allow a replica car to be placed there.
It was a silent visit and the jury were not addressed.
Mr Webster stands accused of fraudulently obtaining more than £200,000 after cashing in insurance policies following the death of his first wife Ms Morris, who was from Oldmeldrum.Malcolm Webster is charged with murdering his wife Claire Morris
The 51-year-old is further charged with deliberately crashing his car in Auckland in February 1999 in a bid to kill his second wife, Felicity Drumm, who was a passenger.
It is also alleged he intended to bigamously marry Simone Banarjee, from Oban, Argyll, to gain access to her estate.
It is claimed he told her he was terminally ill with leukaemia when he was actually in good health.
The trial, before Lord Bannatyne, began on 1 February.
It is expected to last several more weeks.
