He recently learned he would not need to report for military training until next month (Apr11), allowing the Prince to tag along for the gruelling journey.
Harry will spend five days trekking in freezing temperatures with a number of servicemen who were wounded in Afghanistan - and he can't wait to tackle the feat.
In a statement Prince Harry says, "What the Walking With The Wounded North Pole Team is undertaking is an enormous adventure of the most challenging order."
The soldiers are expected to reach the landmark by 26 April (11) and hope to raise $3.2 million for charity through donations and sponsorships for the expedition.
The entire trek will take about four weeks, but the Prince will bow out early in order to honor his Army commitments and serve as the best man at his brother William's upcoming nuptials to Kate Middleton on 29 April (11).
Prince Harry is patron of the Walking With the Wounded charity.
