MammothMarch is back in Oregon!
After three sold out events in a row, MammothMarch will be back at Silver Falls State Park on March 20, 2027!
Nestled in the foothills of Oregon’s Cascade Mountains, the Beaver State’s biggest State Park is a standout scenic treasure that features 10 impressive waterfalls and a dense forested landscape. Our 20-mile hiking route will put everything on display that the “crown jewel” of the Oregon Park system has to offer.
Located just 90 minutes south of Portland and 30 minutes east of Salem, MammothMarch Oregon makes for the picture-perfect hiking getaway.
Master the challenge and spend a beautiful day hiking 20 miles at a stretch. Getting your finisher medal, you will be exhausted, but proud and happy... as well as part of our amazing community of nature-lovers, hikers and MammothMarch addicts!
