About Our Xtreme Hike


We can’t wait to bring the CF community together for Xtreme Hike!! Our 2022 Xtreme Hike event will feature in-person and virtual experiences to help make a difference for people living with cystic fibrosis.

This year, we will be reaching for the clouds and summiting one of Yosemite’s most impressive peaks, Clouds Rest. Hikers will embark on the Mist Trail from Yosemite Valley (4000 ft) and hike 4 miles until they reach Nevada Falls. On the journey up to Nevada Falls, hikers will see views of Vernal Fall and will hike behind the famous Half Dome. From Nevada Falls, hikers will travel through Little Yosemite Valley, to the John Muir Trail and then all the way up to Clouds Rest at an impressive 9927 ft. At Cloud’s Rest, hikers will be able to see a full panorama view of the breathtaking Yosemite National Park and will even be able to look down on Half Dome! This is an out and back trail, so hikers will return the same way they came up. The hike is about 22 miles round trip with approximately 6000 ft of elevation gain.

For our shorter trail option, hikers will embark on the Mist Trail from Yosemite Valley (4000 ft) and hike about 4 miles until they reach Nevada Falls. From Nevada Falls. On the journey up to Nevada Falls, hikers will see views of Vernal Fall and will hike behind the famous Half Dome. From Nevada Falls, hikers will continue to Little Yosemite Valley Camp where they will enjoy the beautiful views of the lake and wilderness. Hikers will loop around the lake and then head back to the valley floor. This hike is about 10 miles with approximately 2300 ft in elevation gain.

What makes the Xtreme Hike Unique?

Since 2012, the Northern California Xtreme Hike has hiked over 195 miles in iconic locations including Yosemite National Park & Lake Tahoe and raised over $1,180,000 in support of finding a cure to cystic fibrosis. For our 11th year, we will be hiking in the beautiful Yosemite National Forest. 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 $2500 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!
