Melissa Street, 38, of Darton, who is currently training to be a paragliding pilot, is taking part in an ‘Awesome Foursome’ series.
It will include the world’s highest indoor bungee jump, a 150ft freefall experience, a zipwire and an abseil into free air.
The activities will be taking place on Saturday, January 28 at the Magna Centre in Rotherham.
She will also be taking on Mount Everest next November to raise money for the same cause.
Melissa told the Chronicle: “I’ve always loved all things adventure, since being young.
“I have personal links to the hospice as my grandma unfortunately suffers with dementia - they do a really amazing job at looking after people and it only feels right to do something nice and be able to give back to a charity that is particularly close to my heart.
“Doing this will help make a difference for elderly patients and those living with dementia.”
