The 77-year-old was transferred by ambulance to the sheep ranch his family owns in southern Israel, accompanied by a full medical team.
A war hero and politician who was for decades one of Israel's most controversial figures, Mr Sharon found popularity as prime minister between 2001 and 2006, engineering Israel's Gaza pull-out in 2005.
He was kept in the long-term care unit at Tel Hashomer Hospital after suffering the strokes in January 2006.
There has been no improvement reported in his condition.
