Just east of Springfield, the Thurston Hills Natural Area offers eight trails, which can be combined for more than 9 miles (14.5 km) of riding. The main trailhead is located off Main Street and 75th Street in Springfield. The 660-acre (267 ha) natural area is a gem of green space near the urban center. The trailhead provides restrooms, picnic tables, an information kiosk and a bicycle cleaning and repair station.
These predominately green-rated routes are perfect for new mountain bikers and kids. Two of the trails offer a separate downhill trail dedicated to mountain bikers. In addition to mountain biking trails, there is also the Mossy Maple Trail which offers 6 miles (9.7km) of round trip of hiking trails.
