About Day Passes Mountain biking on the Millstone Trails requires the purchase of a Day Pass if you are not a Member. Members do not have to purchase Day Passes Walking, running and hiking on the trails is always free
If you like our trails, whether it be for walking, biking, skiing, snowshoeing, photography, history, or just enjoying the scenery, we encourage you to make a tax-deductible donation. Donations and mountain bike day passes are the source of funding that keep the Millstone Trails open. 100% of these funds go directly to trail maintenance, primarily materials and tools, parking maintenance and grooming trails in the winter, and the administrative expenses of operating a public recreation area. Thank you for enjoying and supporting the Millstone Trails.
