Join families affected by histiocytosis for our 21st annual hike in Yosemite as we take on two mighty challenges:
  • Raising $200,000 to help fund a cure for histiocytosis, and
  • Hike to the Half Dome cables!
Together we will fund a cure!
About the Hike

Please join us for our 21st annual Hike For A Cure in Yosemite. As we did for our first ten years, we will be hiking together to the cables at the base of Half Dome. You'll be part of a very special group of family and friends working together to raise funds to find a cure for histiocytosis.

Saturday night, due to COVID protocols in Yosemite, we'll distribute a boxed dinner and have an informal opening event at the Curry Village amphitheater.  Sunday morning we leave before dawn. With each step on the 17 mile hike we are reminded of the exhausting, seemingly never-ending journey faced by those fighting histiocytosis. The hike is hard - no doubt. Fighting histiocytosis is so much harder.

Sunday night over pizza in front of our tent cabins we will celebrate success and then say our goodbyes to our histio friends at Monday morning. Back at home, school or work you will have many stories to share with your sponsors - not just about the hike itself, but also about the "Histio Heroes" and families that you met.

In partnership with the Histio Cure Foundation (HCF) our goal has always been to have a cure for histiocytosis in place by 2021. Since not all of us will be able to join together in Yosemite we will have a H4AC Celebration over Zoom on Saturday October 23. There you will hear from the doctors that have been funded by HCF on their success in finding a cure for this rare disease. 

We look forward to seeing you in Yosemite for this celebration of success!
And we invite you to join us in Yosemite in October 2022 for our rescheduled final H4AC in Yosemite.

About Us

When our son Anton (center) was diagnosed with Langerhans Cell Histiocytosis (LCH) three months after his birth our world was in turned upside down. In those days the survival rate for infants with the disease was less than 50%.​ It was a very hard time for us.

We were incredibly grateful that he survived this battle, and came away determined to help those that would have to follow us down this difficult path. With the support of our family and friends we created Hike For A Cure in 2001 to raise money to fund the research that would lead to a cure for histiocytosis. In the 20 years since that first hike the participants on Hike For A Cure have raised $2.2M!

Our goal has always been clear: to have a cure for histiocytosis in place by 2021. 
Though is the big year, due to COVID we'll postpone hold our big celebration in Yosemite in 2022. Your support is the key to curing this disease. All donations go to the Histio Cure Foundation, which sends 100% of those funds directly to researchers focused on histicytosis. Together we will fund a cure!

Hike Weekend Detail

Departing before dawn and hiking 17 miles and 4800 vertical feet in one day is an intense physical challenge. Yet in the company of enthusiastic friends, family and kids you will be surprised by what you can accomplish. Along the way the way are remarkable vistas and lunch spots that can make for a great personal summit for the day.

Our goal is to come together as a community to accomplish something bigger than any one of us: an daunting physical challenge and an equally tough financial goal. In joining us and achieving your own physical and fundraising goal you will be making a difference in your own life and the lives of those fighting histiocytosis.

Note that for 2021 we will need to follow federal COVID protocols in Yosemite National Park.  This will require that we wear a mask indoors (other than our tent cabins) or outdoors near others not in our pod. Curry Village Dining Pavillion will be closed, so we will be having our group dinner Saturday and Sunday outdoors, in our pods safely separated.
