Mystic is one of the quieter trailheads on the Mickelson Trail, making it a good spot to start if you’re looking to avoid crowds. You’re surrounded by forest and old railroad history here. The trail used to be a railroad line, and you’ll see signs of that along the way, including tunnels and trestles.
It’s a solid access point whether you’re biking or hiking. From here, you can head north toward Rochford or south toward Hill City, both sections are scenic and not too steep.
