Trails Challenge

Grass River Natural Area
6500 Alden Highway,
Bellaire, MI 49615
Take the Trails Challenge and discover the beauty and serenity that Grass River Natural Area has to offer by hiking all seven trails between June 1 and September 30. The Trails Challenge is free and is designed for all ages and fitness abilities. There is no need to register for this program, just go out and enjoy a hike with your friends, family, co-workers or enjoy the solace of being in the forest by yourself. Once you have hiked all of the trails, fill out and submit a brief online trail log with basic information about your experience on these hikes. You may also download a printable trail log to fill out along the way and hand in at the Grass River Center.

After you complete the trail log, visit the GRNA Center to receive a Rent One, Get One coupon for Paddles and Pedals in Bellaire and get entered to win a sweet GRNA swag pack. Kids under 12 will receive a Trail Challenge Trekker certificate. Be sure to check the nature center hours as we are only open on the weekends after Labor Day.
