The Hiker’s Journey

Welcome to Xtreme Hike Yosemite 2019.  Xtreme Hike is about reaching new heights – physically and philanthropically.  It’s a journey of passion, determination and personal triumph, as much as it’s an opportunity to make a difference in the lives of people with Cystic Fibrosis.

Since 2012, the Northern California Xtreme Hike has hiked over 144 miles in iconic locations including Yosemite National Park & Lake Tahoe and raised over $670,000 in support of finding a cure to cystic fibrosis. For our 8th year, we will be return to Yosemite. Join us on this amazing journey to view new sights and climb higher heights.

In just one day, a dedicated team of Xtreme Hikers will hike to the top of El Capitan at 7,500 ft in elevation. This is a total of 22 miles roundtrip with ~4,500 feet elevation gain. The hike starts by traveling on the Yosemite Falls Trail to the top of Upper Yosemite Falls.  We will then take a side trip to Yosemite Peak.  After Yosemite Peak, we continue on to Eagle Peak before reaching El Capitan.


“Xtreme” means something different to everyone—our guides have crafted an additional, a route for those who do not want to be hiking on the mountain as long. We will turn around after Yosemite Peak, offering a 10 mile hike with 3,000 feet elevation gain (in 5 miles up).  Both routes will include vistas of Yosemite Falls, Half Dome, Yosemite Valley and other iconic landscapes. Select your challenge and join us on Xtreme Hike 2019 where the views are incredible and the passion is tangible.  

As the name states, this is a challenge of xtreme proportions. For many, you are committing to hiking further and raising more money than you have ever done before. As participants prepare for the physical challenge, hikers are encouraged to raise $2500 through their personal and social media campaigns. Not to worry, we are here to support you every step of the way!
