About the Arizona Xtreme Hike

The Xtreme Hike at the Grand Canyon 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 longer, healthier lives and to one day find a cure.

The CF Foundation Xtreme Hike requires sacrifice and determination and challenges each hiker to reach personal and philanthropic milestones which celebrate and support those living with CF. Xtreme Hike Grand Canyon is limited to 25 hikers per hike. Each hiker strives to reach a fundraising goal of $3,500 or more.

The Arizona Fall Xtreme Hike at the Grand Canyon is September 27-29, 2019. Hikers will descend the Bright Angel Trail and ascend the North Kaibab Trail. This is a 23.5-mile South Rim to North Rim hike and is completed in one day.

With only 25 spots available, this is an exclusive opportunity to conquer one of the most challenging hikes in the United States. Due to the difficulty of this hike and the dangers inherent to Xtreme Hiking, we reserve the right to restrict hikers from entering the Grand Canyon and/or completing the challenge if not sufficiently prepared.

THIS EVENT FILLS UP QUICKLY. Registration will be accepted on a first-come first-served basis.

Xtreme Hike Weekend

Hikers check-in at the CFF Arizona Chapter office (2777 E. Camelback Rd.) in Phoenix, AZ on Friday, September 27th. All Xtreme Hikers travel together on a comfortable motor coach to the South Rim where lodging is provided (double occupancy) at the Yavapai Lodge. The group enjoys a pre-hike dinner on Friday evening.

Hikers are transported to the Bright Angel Trailhead early Saturday morning, September 28th. Hikers will be on the trail at 5:00am. Most Hikers will complete the Rim to Rim hike in 12-14 hours. Upon completion of the hike on Saturday, we will revel and recover at a ‘Top of the Rim’ celebration. Hikers will be shuttled to the North Rim Lodge (double occupancy) for dinner on their own.

The post-hike celebration on Sunday, September 29th, caps the Xtreme Hike experience before our return to Phoenix.
