MammothMarch is back in Upstate NY!
We are beyond excited to bring MammothMarch back to Letchworth State Park, renowned as the “Grand Canyon of the East”. After two sold-out editions, MammothMarch Upstate New York takes place on August 9, 2025. Along our 20-mile hiking route, you will conquer one of the most scenic areas in the Eastern US.
Our single-circuit loop leads along the Genesee River, through lush forests, features spectacular waterfall and gorge views, and has quickly become a fan favorite among our nationwide hiking community.
Several times voted as “Best Park in the United States”, Letchworth is located just an hour east of Buffalo/south of Rochester and will once again be one of the most scenically magnificent MammothMarches in our 2025 calendar.

Please note that the route will be made available for download approximately 2 weeks prior to the event. Please note that the route is preliminary and may be adjusted due to weather issues, official directives and/or organizational matters. The route will be marked 1-2 days prior to event day. Should we notice parts of the route being inaccessible, extremely wet/muddy we will of course adapt it to local conditions at short notice.
