The Fellows Lake Trails are one portion of the Dirt 66 Master Plan, a part of our region’s trail system, that will span from Fellows Lake on the east to Sac River Mtn. Bike Trails on the west. Future plans include integration with the Fulbright Spring Greenway trail and several Springfield-Greene County Parks. This project is being funded by nonprofit TrailSpring in partnership with Ozark Greenways and City Utilities. These soft surface (aka natural surface/unpaved) trails are open to hiking, running, and optimized for mountain biking. The trails are open from sunrise to sunset.
