Gallatin Regional Park, located 3 miles northwest of town, is a very pleasant spot for a shorter off-road run. The 87-acre park features ~2 miles of gravel trails that make a figure eight loop around two small ponds. The terrain is flat and fairly open, with great mountain views. There are benches along the trail, and the park features a playground, swimming area, climbing boulders, and porta-potties.
Longer Run: There are new-ish residential subdivisions both north and south of the park, which, while not overly scenic, feature quieter roads that are good for running.
