Generations of families in Austin have ridden the Zilker Zephyr, a 25-minute miniature train ride that that takes younger children through bucolic Zilker Park. It will whet your appetite for the Bertram Flyer, a three-hour, round-trip ride through glorious Texas Hill Country. Operating on weekends, you’ll view the rolling farmland, fields of bluebonnets, and visit the historic Bertram Train Depot, founded in 1912.
