Important Note: To protect the health and well-being of the cystic fibrosis community and CF Foundation staff during the COVID-19 outbreak, we will no longer be hiking in Yosemite, CA. Instead, we will be hosting a local one-day Xtreme Hike at Northstar California Resort in Truckee, CA. While this opportunity is open to everyone, we are not providing or encouraging overnight accommodations. In addition, we are not encouraging air travel or lengthy drive times to attend the event. For those unable to attend in person, we will be providing a virtual option to participate.

What makes the Xtreme Hike Unique?
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 9th year, we will be hiking in the beautiful Northstar California Resort. Join us on this amazing journey to view new sights and climb higher heights.

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 $650 through their personal and social media campaigns. Not to worry, we are here to support you every step of the way!

You will not want to miss this opportunity to meet like-minded individuals and challenge each other to help cure cystic fibrosis one step at a time!
