More than 1000 witches are expected to turn out to try and break an official world record for the most witches in one place.
It's all part of the 400th anniversary of the Pendle Witch Trials which began on August 18th.
Organisers are also hoping to raise in excess of £50,000 for Pendleside Hospice.
The walkers will set off at 11:15 and head for the summit of Pendle Hill, which for generations have been symbolic of witchcraft as well as being a site of reverence for Pagans and Quakers.
Simon Tattersall, one of the organisers of the event, said: “It’s great news that Pendle Witch Walk has been recognised by Guinness World Records as a World Record attempt.
“We’re hoping for a great event and a truly memorable day. The world record attempt for the greatest gathering of “witches” will give everybody’s efforts an undisputable measure of achievement. It will bring huge attention to the Burnley and Pendle area and our tumultuous history, but more to the point we hope that via their sponsors, walkers will raise in excess of £50,000 for Pendleside Hospice.”
