About Our Xtreme Hike

Grand Canyon Xtreme Hike is one of the most challenging in the country. Where else can you conquer one of the seven natural wonders of the world?! The Arizona Chapter of the CF Foundation hosts this extraordinary endurance event to raise awareness and funds to help those with CF live long, fulfilling lives and to one day find a cure. 

The CF Foundation Grand Canyon Xtreme Hike requires sacrifice and determination, and challenges each hiker to reach personal and philanthropic milestones which celebrate and support those living with CF. In addition to the physical commitment, each hiker takes on the challenge to reach a fundraising goal of $4,000 or more!

  2. The 2023 Grand Canyon Fall Xtreme Hike is September 29-October. Hikers will descend on the Bright Angel Trail and ascend on the North Kaibab Trail. This is a 23.9-mile South Rim to North Rim hike.

The Hiker's Journey

2023 Grand Canyon FALL Xtreme Hike – September 29-October 1
