Our HikesDonate


PasstoPass provides multi-day supported backpacking trips for people with Parkinson’s Disease (PD).  Trips are planned and led by people with Parkinson’s or close connections to PD so that routes, trails, and distances are selected with the physical challenges of participants in mind. The key is support. Support hikers help on the trails and in camp. Pack llamas carry gear so that Parkinson’s hikers only have to carry a light day pack. The support helps people with PD have a positive hiking experience.

As a nonprofit, all volunteer organization, PasstoPass does it all on a shoestring led by people with Parkinson’s. PasstoPass pays for the llamas, shared community gear, emergency satellite communications, wilderness First Aid training, insurance and operating expenses. 100% of PasstoPass’ income comes from donations.

The benefits of PasstoPass hikes are both mental and physical. Studies have proven that vigorous exercise improves Parkinson’s symptoms and may slow progression of the disease.  Support provided on PasstoPass trips helps hikers overcome the challenges of PD, boosting their morale and confidence. The shared experiences create deep bonds and lasting friendship between hikers.

Although Parkinson’s is a progressive disease, PasstoPass trips allow people with PD to  live in the moment, to experience exhilarating physical activity, to challenge themselves, to celebrate success, to hope and to experience the joy of being outdoors.

2023 Completed PASStoPASS HIKES

Our trips are planned and led by experienced hikers who have Parkinson’s or are close to someone who does. Most PasstoPass trips are up to six days long and take place along sections of the Pacific Crest Trail in the Cascade Mountains of Oregon and Washington State, as well as the John Muir Trail in California. Support hikers provide assistance on the trail and pack llamas carry gear so PD hikers only need to carry a light day pack on most hikes. Please read our 2023 hike details and the FAQs about what to expect on the hikes.

We completed our 2023 hikes. A total of 9 hikes with 46 PD hikers and 59 support hikers. We used 16 llamas and hiked 2,629 cumulative miles. Hikers came from 12 different states and 1 Canadian province. 



Seeing people overcome and exceed physical challenges is inspirational. To watch people work together to accomplish what they could not do alone is awesome. And to witness it all in the breathtaking beauty of the Sierra and Cascade Mountains is truly extraordinary!








PasstoPass was founded by Bill Meyer, whose love affair with the wilderness spans half a century. Diagnosed with Parkinson’s Disease in 2009, Bill was determined to keep hiking. As the disease progressed, his tremors and balance got worse. Hiking became increasingly difficult, especially carrying a heavy backpack over his Deep Brain Stimulation (DBS) batteries. Bill had seen pack mules on the Pacific Crest Trail and thought they could be the answer. But if he used mules, he needed people to help. So Bill reached out the NW Parkinson’s Foundation looking for other hikers he could enlist. He found Ken Kisch, a fellow hiker with Parkinson’s and PasstoPass was born.

The first PasstoPass trip set off on August 20, 2016. Four hikers with Parkinson’s, a support team of seven and six pack mules hiked nearly 75 miles on the Pacific Crest Trail in 9 days. Their goal was to raise money for Parkinson’s research, increase awareness of the disease and to prove that physical activity can relieve Parkinson’s symptoms. The trip was a success so planning began for another PassToPass hike in 2017.

PasstoPass has grown and adapted based on lessons learned. Pack llamas replaced mules, trips were shortened, more hikers signed up and PasstoPass became a non-profit. In 2022, PasstoPass offered 8 hikes with varying levels of difficulty. 40 hikers with Parkinson’s, 45 support hikers and 9 llamas completed the trips,  a cumulative total of 2188 miles.


PasstoPass needs your help. We are the only organization that provides supported multi-day backcountry hikes for people with Parkinson’s. 100% of our funds come from donations, and we are completely supported by volunteers. Please consider making a tax deductible contribution so that we can add more trips and expand geographically to meet the increasing demand. Your donation WILL change the lives of people living with Parkinson’s Disease.
