Join HCF on Sunday, October 12, 2025,  in Yosemite Valley, CA, for a special reunion of Hike for a Cure families and friends as we take on two mighty challenges:

• Hike from Yosemite valley to “Histio Lookout” overlooking Half Dome
• Support and encourage Histio families and researchers fighting histiocytosis

Hiking 18 miles and 4,800 ft in elevation is hard. But fighting Histiocytosis is much harder. Together we can do it!  Learn more.
