The AA estimates 17 million cars will take to the roads over the holiday period, with the busiest periods expected to be this afternoon and Good Friday morning.
But they added that the roads may not be as busy as usual as the cold weather was likely to make this more of a "stay-at-home Easter".
Visit England said around 6% of the adult population were planning a break in the UK involving at least one overnight stay this Easter.
These trips were likely to generate around £600 million for the UK economy.
